Question

humans are typically fueled by aerobic respiration. in which scenario might anaerobic respiration begin instead?
o after sitting at a desk for 3 hours
o after walking across a basketball court
o after eating a high fat meal
o after running 20 miles

Explanation:

Anaerobic respiration occurs when the body's oxygen - supply is insufficient for the energy demand. Running 20 miles is a strenuous activity that can deplete oxygen supplies quickly, triggering anaerobic respiration. Sitting, walking across a basketball court, and eating a high - fat meal do not typically cause such a significant oxygen shortage.

Answer:

after running 20 miles
