Answer:
More Carbon dioxide is removed from the blood and exhaled in the breath
Explanation:
During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it. So, when you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.
Answer:
A complete response
Explanation:
This follows the all-or-none principle, which states that the strength of the response of a nerve or muscle fiber does not depend on the strength of the stimulus acted upon it. If the stimulus is more that a certain threshold, the impulse will have a complete response, or otherwise none at all.
Answer: Acetyl-CoA
Explanation:
Acetyl-CoA can be obtained from the pyruvate, the end product of aerobic glycolysis. Also, Acetyl-CoA is the one of the starting materials of citric acid cycle.
For lipid synthesis, biotin carries activated CO2 that is incorporated into acetyl-CoA to form Malonyl-CoA, which is then elongated to yield various lipids of different length.
Thus, Acetyl-CoA is the building block of lipid synthesis
