Using a series of arrows, draw the branched metabolic reaction pathway described by the following statements, and then answer the question at the end. Use red arrows and minus signs to indicate inhibition.
L can form either M or N.
M can form O.
O can form either P or R.
P can form Q.
R can form S.
O inhibits the reaction of L to form M.
Q inhibits the reaction of Oto form P.
S inhibits the reaction of O to form R.
Which reaction would prevail if both Q and S were present in the cell in high concentrations?
a. L → M
b. M → O
c. L → N
d. O → P
Answers
Answer:
1) The branched metabolic reaction pathway is attached.
2) The most prevalent reaction is L-->N
Explanation:
The reaction that eventually will prevail is the formation of the N molecule.
When Q and S are in high, they will inhibit the formation of P and R which are the molecules that form them. So, Eventually, there will not be P and R molecules, and hence, there will not be any more Q and S molecules.
L can still form equally M and N molecules. But as M forms O, and O inhibits M formation, with time, the higher O concentration is, the less M formation there will be.
On the other hand, N has no molecule that inhibits its production. So L turns to N formation, predominating this reaction.
The reaction that would prevail if both Q and S are present in the cell in high concentrations is L → N (Option c).
In a chemical reaction, a substrate is a molecule that reacts with a given enzyme to generate one or more products.In this case, L is the first substrate whose reaction produces N and M, while Q and S are the last products observed in this series of reactions.In turn, M acts as a substrate to form O as an intermediate, which subsequently serves as a substrate to form P and R.Finally, P serves as a substrate to form Q, while R serves as a substrate to form S.The series of chemical reactions are as follow:
L → N + M → O → P + R → Q + SIn this case, it is also important to remark that a given product of a chemical reaction can also inhibit the enzyme's activity (e.g., O is an intermediate that inhibits the formation of M).In consequence, the reaction that would prevail if both Q and S are present in the cell in high concentrations is L → N (Option c).

Explain what the impact of mutations in myosin that disrupt ATP binding would have on the power stroke during muscle contraction. and hydrolysis Skeletal muscle arrangement, ATP binding and correct muscle contractions
Answers
Answer:
These cells will be atrophied because muscle contractions can't occur.
Explanation:
In muscle cells, ATP binding causes a conformational change in the structure of myosin, thereby these filaments move to a high-energy configuration. The muscle contraction is caused when this high energy state is amplified in the actin filaments that bind to myosin, in a process dependent on the ATP hydrolysis. The myosin-actin cycle is repeated by binding another ATP molecule on the myosin head, producing the contraction of muscle cells.

A. Solar energy changes ADP into ATP.
B. NADPH turns into NADP+.
C. Glucose forms from carbon dioxide molecules.
O D. Electrons in the third protein gain new energy from light.
Answers
Answer:
A. Solar energy changes ADP into ATP.
Explanation:
The phase of the photosynthesis is based on the light that reacts as the pigment molecule absorbs energy from the sunlight and the photons strike the photosystem to initiate the photosynthesis. Energy transports through the electron that pumps hydrogen ions and forms an electrochemical gradient. The ADP is a combination of phosphate to form the ATP in the reaction i.e ADP +energy to ATP plus water. This usually takes place by the storage of high energy to ATP as sugar molecules that are sent phase of photosynthesis.Answer:
A. Solar energy changes ADP into ATP
Explanation:
Photosynthesis is the process in which plants make there own food by utilizing sunlight that converts water and oxygen into carbon dioxide and energy.
There are two systems in photosynthesis: Photosystem II and Photosystem I.
In photosystem II ADP + P is converted into ATP driven by electron gradients formed in the thylakoid membrane.

When making choices for food, I tend to take several factors into consideration. Some of these factors include;
1. The taste of the food: If the food tastes good and is not too spicy I am more inclined to choose such food.
2. Length of time for preparation: Especially on stressful days, I tend to consider the length of time required to prepare a healthy meal. If it takes so much time I am more inclined to eat fast food which is not a good choice.
To change this negative outcome, I hope to plan my affairs for the day and prepare healthy meals beforehand, which could be stored in the refrigerator and reheated when I need it.3. Method of Preparation: Some foods require paying attention to details. For example, food that uses up, a lot of vegetables would require thorough washing to prevent particles in the food. Busy days also get me exhausted with no strength to pay attention to these protocols.

Why do you think these groups have a high risk of osteoporosis
Answers
Answer:
lack or low calcium level
Explanation:
when a person has a low calcium intake, these people are susceptible to having osteoporosis as their bodies would be lacking of much needed calcium.
Low calcium intake increases osteoporosis risk. Lifelong calcium deficiency causes osteoporosis. Low calcium consumption causes bone loss, early bone loss, and fractures.
What is osteoporosis?Osteoporosis is a disorder that causes bones to become brittle and more prone to breaking, which increases the risk of fractures. It manifests itself gradually over the course of several years, but the condition is typically not recognized as a problem until a bone breaks as a result of a fall or a sudden impact. A broken wrist is the type of injury that occurs most frequently in people who have osteoporosis.
People who consume inadequate amounts of calcium are at increased risk for developing osteoporosis. The deficiency of calcium over a lifetime is one of the factors that can contribute to the development of osteoporosis. A diet deficient in calcium has been linked to decreased bone density, an accelerated rate of bone loss, and an increased risk of fractures.

the “good genes hypothesis” proposes that people with physical qualities like averageness, symmetry, sex prototypicality, and youthfulness are more attractive because they are better-quality mates. the “good genes hypothesis” is from which approach to psychology?: 1) evolutionary 2) psychodynamic 3) cognitive 4) biological
Answers
The correct answer is 1) Evolutionary
Explanation:
The "good genes hypothesis" argues traits of the opposite sex that are considered as positive or attractive reflect evolutionary traits and therefore are indicators of a better-quality mate. Indeed, this theory argues attraction is connected to better chances of survival or better chances to reproduce. This belongs to the evolutionary approach in psychology because these "attractive" traits are the result of evolution because only the "fittest" individuals reproduce and their genes prevail over time.

g A variable trait in corn is the presence or absence of knobs at particular sites on some chromosomes. The allele present on each chromosome determines whether or not that chromosome has a knob. Suppose that one member of each of two pairs of homologs in a corn plant has a knob. If this plant is crossed with a knobless plant, what percentage of the offspring is expected to have only knobless chromosomes
Answers
Answer:
50%
Explanation:
The allele present on each chromosome determines whether or not that chromosome has a knob. Suppose that one member of each of two pairs of homologs in a corn plant has a knob.
This means that on a chromosome with two chromatids, the allele present on one chromatid causes the chromatid to possess knob while the other does not making the plant an heterozygous...
If this plant is crossed with a knobless plant, one whose Chromebook is without knobs, we have
II x II
II - 50% with a knobbed chromatid
II - 50% with only knobless chromosomes.
The first to the left is knobbed, thus the percentage of offspring expected to have only knobless chromosomes would be 50%.
Assuming a diallelic gene and complete dominance, the percentage of the offspring that is expected to have only knobless chromosomes is 50%
----------------------------
Available data:
Trait presence absence of knobsPlant 1: One member of each of two pairs of homologs in a corn plant has a knobPlant 2: knobless plantWe will assume complete dominance, and that the presence of knobs is the dominant trait.

B) Part of the chromosome breaks away, but reattaches in inverse orientation.
C) An extra chromosome is added, causing mismatching of the chromosome pairs.
D) There is a misreading of the base pairs during translation.
Answers
Answer:
C) An extra chromosome is added, causing mismatching of the chromosome pairs.
Explanation:
Mutation is any change, whether big or small, that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs.
According to the question, frameshift mutation is a mutation that causes the normal reading frame of the nucleotide sequence to be altered. It is caused when an extra chromosome is added (insertion) or when one chromosome is removed (deletion). In either way, there will be a mismatch or alteration in the chromosome pair, hence affecting the reading of the nucleotide sequence.
In frameshift mutation, the insertion or deletion causes the
normal CODONS (triplet nucleotide) to be missing or incomplete, hence, disrupts the manner at which the reading takes place (reading frame). Note, frameshift mutation only occurs as a result of insertion or deletion of chromosomes/bases that are not multiples of three that can maintain the normal reading pattern/frame.
