Which process occurs within the mitochondria?
Answer:
Krebs cycle
Explanation:
The Krebs cycle is a set of chemical events that all aerobic organisms employ to generate energy by converting acetate (which comes from carbs, lipids, and proteins) to carbon dioxide. There are various alternatives to the TCA cycle in theory, but it appears that the TCA cycle is the most efficient.
Answer: Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria. ... In heart muscle cells about 40% of the cytoplasmic space is taken up by mitochondria.
Explanation:
The process is called oxidative phosphorylation and it happens inside mitochondria. In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP).

What role do enzymes play in chemical reactions?
Answer:
Enzymes allow many chemical reactions to occur within the homeostasis constraints of a living system. Enzymes function as organic catalysts. A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy of reactions.

What is the main difference between combustion and respiration?
A. respiration occurs at high temperatures without enzymes to release energy
B. respiration uses enzymes at normal body temperature to release energy
C. combustion uses enzymes at normal body temperature to release energy
D. respiration does not use a catalyst but combustion does use a catalyst
Answer:
A. respiration occurs at high temperatures without enzymes to release energy
Explanation:
The respiration is the transfer of oxygen from the environment to the cells and removal of carbon dioxide from the cells is often referred as cellular respiration by which an organism obtains an energy.
But combustion is the burning of any hydrocarbon fuel in the air resulting the liberation of heat energy and other combustion by products like carbon dioxide, steam and Nitrogen. Practically, in addition to these gases there may also be the presence of sulphur dioxide, nitric oxide and oxygen which depends upon the composition of fuel and the amount of air supplied for combustion.

What type of transport was shown in the second animation?
A. active transport with the help of transport proteins
B. passive transport by simple diffusion across the membrane
C. passive transport by facilitated diffusion with the help of transport proteins
Answer:
C. passive transport by facilitated diffusion with the help of transport proteins
Explanation:
The electron transport chain (shown in the second animation) establishes a proton gradient across the inner mitochondrial membrane. ATP synthase uses the energy stored in the proton gradient to catalyze the synthesis of ATP. The molecular machinery involved in this process converts chemical energy to mechanical energy and provides a great example of the relationship between the structure and function of macromolecules.
Answer:
C. passive by facilitated diffusion with the help of transport proteins
Explanation:
Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes.

The hemoglobin protein of a human and a frog differ by 67 amino acids. How many amino acids are most likely different between a human and a chimp?
A. none
B. fewer than 67
C. 67
D. more than 67
Answer:
B. Fewer than 67
Explanation:
Humans are much more closely related to chimps than frogs, so the genetic information that codes for their proteins will differ much less.
Based on the evolutionary relationship between humans and chimpanzees, it is highly likely that humans and chimpanzees share a large portion of their genetic material, including the amino acid sequence of hemoglobin. Therefore, it is most likely that the answer is B. Fewer than 67 amino acids are different between a human and a chimp.
What is the hemoglobin of different animals?The hemoglobin protein is a vital protein in both humans and chimpanzees that helps transport oxygen in the blood. While there may be some variations in the amino acid sequence of hemoglobin between humans and chimpanzees, it is expected that most of the amino acids will be the same since hemoglobin performs a critical function in both species. Additionally, any differences in the amino acid sequence of hemoglobin between humans and chimpanzees are likely to be fewer than 67, as this is the number of differences between humans and frogs, which are much more distantly related species.
Hence, it is most likely that the answer is B. Fewer than 67 amino acids are different between a human and a chimp.

James needed to have his hernia surgically repaired. This can be done through laparoscopic surgery. The surgeon must cut through to the herniated area and put a Teflon mesh underneath the hernia to close it off and provide more support to the area. Use your knowledge of anatomy to select the correct sequence of structures that would be cut for this procedure. Make sure you select the structures in the order they would be cut by the surgeon.
Answer:
The structures that the surgeon will cut to place the Teflon mesh from external to internal are:
Skin,
hypodermis,
subcutaneous fat,
the external oblique aponeurosis,
the internal oblique,
the transverse abdominal,
the peritoneum.
Explanation:
For the surgeon to put the Teflon mesh underneath the hernia, the professional has to cut the most external organ, which is the skin, with all its layers, epidermis, dermis, and hypodermis. Underneath this tissue is the subcutaneous fat, which protects the muscles, regulates the temperature, and stores energy. Subcutaneous fat is different in every person. Some can have a lot of it and others a thin layer. The next cut will be on aponeurosis, which is a tissue that surrounds muscles. Then we have the internal abdominal oblique, which is in the anterior area of the abdomen. Below it, it is the transverse abdominal, and then the peritoneum, which is the tissue that holds the organs. In a hernia, it has a hole where the organs push through. So, the surgeon has to put a Teflon mesh to close it.

Explain your justification for the changes in trait distribution between years 1 and 10. What do you think will happen to the population by year 15?
Answer:
It will continue to rise.
Explanation:
Genetic variation results in the changes in trait over the period of time. Hence, traits do change over the years, but it is a gradual process. The population will become more stable due to successful traits.
What is genetic variation?Genetic variation refers to the changes in the genotype of an individual. It imparts stability to the population. Genetic variation results from meiotic cell division where recombination of gene produces genetic exchange of heredity material.
Those traits which are successful in nature that means those variations which provide stability to the organism in any environment are favoured. Organisms with such variations adapt, survive and further reproduce to continue their existence. Such traits are transmitted to the progeny as well.
Thus, gradual accumulation of changes in traits contribute to a more stable population over the span of years.
Therefore, changes in traits are important in determining the track of evolution on earth.

Distinguish between gaseous exchange and respiration
Answer:
Respiration is the process in which food is oxidized to release energy. Complex organic compounds are converted into simpler ones, e.g glucose into CO2 water and energy released. Gaseous exchange is the diffusion of gases from a region of higher concentration to a region of lower one.
Explanation:
Breathing is the physical process by which air is passed on a gaseous exchange surface i.e. ventilation of the gaseous exchange surface. It involves Inhalation and Exhalation.
Gas/Gaseous exchange is the process whereby gasses diffuse across a gaseous exchange surface. In humans, oxygen diffuses from the inhaled air into the blood and carbon dioxide diffuses from the blood into the exhaled air. The gaseous exchange surface here being the Alveoli.
Respiration is the metabolic process whereby organic molecules are broken down to release energy in the cells. In humans, this process takes place inside the mitochondria of cells. Aerobic respiration requires oxygen whereas qnqerobic respiration takes place in absence of oxygen.
