Answer:
a) Because when we exercise, we hydrolyze more ATP to ADP and Pi, and O2 is necessary for the hydrolysis, so we increase our intake of oxygen.
c) Because when we exercise, we produce more CO2 and increased ventilation is necessary to rid ourselves of CO2.
d) Because when we exercise, we use more ATP, and additional O2 is necessary to generate sufficient ATP.
Explanation:
During exercise , our body needs more energy in the form of ATP. This ATP comes from break down of food materials in the mitochondria of the cell during cellular respiration. With the addition of oxygen, more ATP is produced during respiration and this ATP is used by the body. With ATP, carbon dioxide is produced as a waste material which can be removed by exhaled out during breathing.
It will cause vasodilation of blood vessels in the brain.
CO2 is one of the metabolic end products that can alter the
tone of the blood vessels in the brain. High CO2 levels cause vasodilation,
which may cause headache, whereas low CO2 levels cause vasoconstriction, which
may cause lightheadedness. The statements included in the other options are
incorrect effects.
If oxygen is not present, glycolysis would be followed by fermentation
