Question

how many atp molecules (net total) are produced from glycolysis alone?
2
4
32
36
which waste product is exhaled from the body as a result of cellular respiration?
your answer
how would cellular respiration be affected if a person holds their breath too long?
your answer
athletes sometimes train at high altitudes where there is less oxygen. how might this affect their cellular respiration and performance?

Explanation:

1. Glycolysis produces 2 net ATP molecules. Glucose is broken - down in a series of steps, consuming 2 ATP initially and producing 4 ATP, resulting in a net gain of 2 ATP.
2. The waste product exhaled as a result of cellular respiration is carbon - dioxide. During cellular respiration, glucose is oxidized and carbon - containing compounds are broken down, releasing carbon - dioxide.
3. If a person holds their breath too long, oxygen supply is cut off. Cellular respiration will shift from aerobic to anaerobic. Anaerobic respiration is less efficient and produces lactic acid in humans, leading to fatigue and discomfort.
4. At high altitudes with less oxygen, aerobic cellular respiration is affected. The body may switch to more anaerobic respiration, which is less efficient in ATP production. This can lead to decreased performance as the body has less energy available.

Answer:

1. A. 2
2. Carbon - dioxide
3. It will shift from aerobic to anaerobic respiration, producing lactic acid and leading to fatigue.
4. Aerobic respiration is reduced, the body may rely more on anaerobic respiration, decreasing performance.
