In the glycolytic pathway, the enzyme triose phosphate isomerase catalyzes the production of glyceraldehyde 3-phosphate (GAP) from dihydroxyacetone phosphate (DHAP). GAP continues through glycolysis via the reaction catalyzed by glyceraldehyde 3-phosphate dehydrogenase. In a muscle (myocyte) cell culture model, anaerobic conditions lead to cell death when triose phosphate isomerase is inhibited. In this same model, cells with inhibited triose phosphate isomerase survive under aerobic conditions. Briefly explain these findings including a discussion of energy production in anaerobic versus aerobic metabolism.
Answer:
In an anaerobic environment, organisms convert glucose into ethanol or lactate. In this condition, glycolysis generates 2 molecules of ATP and one molecule of NADH with the pyruvate. NADH molecule supports glycolysis by oxidized to NAD+ during the fermentation process.
Here one 6-C molecule breaks into two molecules G3P and DHAP, TPI or triose phosphate isomerase interconvert these two isomers and each triose is responsible for the production of two ATP molecules but if TPI is inhibited then there will be one ATP production which is not enough for supporting cellular process under the absence of oxygen and cell do not survive.
But in aerobic conditions pyruvate converted to acetyl CoA which produces 3 NADH, 1 FADH2, and 1 ATP that will get enough ATP by the oxidative phosphorylation hence will survive even if TPI is inhibited.
Two protein kinases, PK1 and PK2, work sequentially in an intracellular signaling pathway.You create cells that contain inactivating mutations in the genes that encode either PK1 or PK2 and find that these cells no longer respond to a particular extracellular signal.You also create cells containing a version of PK1 that is permanently active and find that the cells behave as though they are receiving the signal even when the signal is not present.When you introduce the permanently active version of PK1 into cells that have an inactivating mutation in PK2, you find that these cells also behave as though they are receiving the signal even when no signal is present.
A.From these results, does PK1 activate PK2, or does PK2 activate PK1? Explain your answer.
B.You now create a permanently active version of PK2 and find that cells containing this version behave as though they are receiving the signal even when the signal is not present.What do you predict will happen if you introduce the permanently active version of PK2 into cells that have an inactivating mutation in PK1?
Answer:
a. PK2 activates PK1
b. no response would be produced
Explanation:
Kinases are enzymes known to phosphorylate different substrates, thereby activating/inactivating them. In this case, a mutation that produces a constitutively (permanently) active PK1 kinase is itself able to continue the signaling pathway, independently of whether or not PK2 is present. This constitutive mutation shows that PK1 is recruited to continue signaling events within the cell and, therefore, PK1 activation is downstream in the signaling pathway. Conversely, cells containing active PK2 and inactive PK1 would be unable to continue the signaling pathway since PK2 activation is upstream of the induction of PK1, and thereby these cells cannot respond to the signal (PK2 activation).

By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.
The dwarf phenotype is recessive to the tall phenotype in pea plants. When one tall plant and one dwarf plant are crossed together, 50% of their offspring are tall, and the other 50% displays dwarfism. What is the genotype of each parent in this cross?
Answer:
Tt (heterozygous tall) and homzygous short (tt)
Explanation:
This question involves one gene coding for height in pea plants. The allele for tallness (T) is dominant over the allele for shortness (tt). This means that dwarf phenotype is recessive to the tall phenotype in pea plants.
According to this question, a tall plant and a dwarf plant (tt) are crossed together. 50% of their offspring are tall, and the other 50% displays dwarfism. This is an equal ratio. Since the dwarf plant can only be "tt", the tall plant must be heterozygous "Tt" to be produced.
Hence, a cross between Tt vs tt will produce ½tall plants and ½short plant.

What is a Beaver’s tail used for
Answer:
The tail is used as a rudder in swimming, as a balance prop while working on land and to signal danger when slapped on the water. Beavers will also store fat in their tails, eating more in the fall so they can survive off the fat stored in their tails through winter if food is not available.
Explanation:
What factors caused the correlation between the reduction in skin pigmentation in humans and migration of human populations away from the equator?(1 point)
A) The exposure of human populations to predators only common to the polar regions caused them to adapt by camouflaging better with the environment.
B) The exposure of human populations to less UV light required a reduction in melanin to produce more vitamin D for healthier bones.
C) The exposure of human populations to new sources of food common to the polar regions caused changes in physiology that resulted in the production of less melanin.
D) The exposure of human populations to new diseases common to the polar regions interferred with melanin production causing lighter skin.
The exposure of human populations to new sources of food common to the polar regions caused changes in physiology that resulted in the production of less melanin.
What is relation of skin colur with geography?Skin color is lighter at high latitudes as compared to equator region beacuse of lower sunlight at higher altitudes and at polar regions. So due to less sunlight, less melanin is produced in our skin.
So we can conclude that option C is the right answer.

When the blood glucose level decreases during a fast or between meals, the pancreas releases glucagon. Glucagon signals the liver to stop consuming glucose and to start producing glucose. Select the statements that describe how glucagon activates glucose production in the liver.
Answer:
Glucagon signals the liver to start producing glucose.
Explanation:
Glucagon signals the liver to start producing glucose from the breakdown of amino acids through gluconeogenesis process. When the glucose level decreases in the body due to fasting or starvation, the pancreas release glucagon which provides signals to the liver to produce glucose form non carbohydrates substances present in our body. This production of glucose increases the concentration of glucose in the blood and the body used this glucose for the generation of energy molecules in the form of ATP.

What is the final product of transcription?
A gene
An amino acid
An mRNA molecule
A stop code
here is the paragraph to read from:
Transcription is the process by which an RNA copy of a gene sequence is created. This copy, known as the mRNA, travels from the cell nucleus to
the cytoplasm. There, it directs the synthesis of the protein. The base code in the mRNA controls the order of the amino acids in the protein.
There are 20 amino acids used to make proteins and different codes for each acid. The tRNA reads the code. Then it brings a specific amino acid to
attach to the growing chain of amino acids. Each tRNA carries only one type of amino acid. It only recognizes one specific code. tRNA is released
from the amino acid until it comes to a stop code. Then the protein is set free from the ribosome.
Answer:
An mRNA molecule
Explanation:
Transcription is a process by which the information stored in a specific fragment of DNA called 'gene' is used to produce a complementary RNA molecule, usually a messenger RNA (mRNA). Subsequently, this mRNA is used as template to produce a polypeptide chain (i.e., a sequentially ordered amino acid chain) through the process of translation. A stop codon, also known as termination codon, is a triplet of nucleotide bases within an mRNA that signals the end of the protein when it is synthesized in the ribosome. There are three stop codons (UAG, UAA, and UGA) that are capable of stopping protein synthesis.
While Rebecca at her locker she can hear students coming from around the corner. Which wave interaction explains why she can hear them
Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.
