Question

You plan to try to escape and try to find more survivors. You need to think ahead to anticipate anything that might happen.

If you are going to escape zombies on the run, why would it be better to use muscle glycogen rather than blood glucose?
A) Because glycogen allows more ATP to be renewed and because it leads to less acetyl-CoA production
None of these answers
B) Because glycogen allows more ATP to be replenished and because it is quickly (near) the site of energy conversion
C) Because glycogen allows more ATP to be replenished and because it results in less lactate production
D) Because glycogen allows more ATP to be renewed and because it leads to less pyruvate production

Answer 1

Using muscle glycogen during high-intensity activity like escaping zombies is beneficial because it allows for the rapid replenishment of ATP and reduces lactate production, delaying muscle fatigue. It's an efficient energy source because it's stored directly in the muscles, allowing for immediate access to energy.

Step-by-step explanation:

If you are going to escape zombies on the run, it would be better to use muscle glycogen rather than blood glucose because muscle glycogen allows more ATP to be replenished and it is quickly available near the site of energy conversion. When you exert a lot of effort and need to tap into energy reserves, muscle glycogen is readily available to produce glucose, which then undergoes glycolysis to generate ATP. As glycogen levels in the muscles begin to decrease, the liver releases glucose, and aerobic processes start utilizing fat metabolism, adjusting to the intensity of the exercise.

Using muscle glycogen for high-intensity activity like escaping is efficient because it reduces the likelihood of significant lactate production that can cause muscle fatigue. Since muscle glycogen is stored locally within the muscles, it is immediately accessible to the muscles for quick energy conversion, which is essential during rapid, high-energy activities, as opposed to relying on the liver to release glucose into the bloodstream.

Therefore, the correct answer to the question is B) Because glycogen allows more ATP to be replenished and because it is quickly (near) the site of energy conversion.
