Question

look at the levels of lactic acid on the screen. why are they increasing?
a) the players are running out of glucose
b) the players are exercising so hard that anaerobic respiration produces a lot of lactic acid
c) the players are producing a lot of lactic acid through aerobic respiration
d) using energy from atp produces lactic acid during exercise

Explanation:

During intense exercise, the body cannot supply enough oxygen to muscle cells to meet energy demands. This triggers anaerobic respiration, a process that breaks down glucose without oxygen and produces lactic acid as a byproduct, causing lactic acid levels to rise. Aerobic respiration does not produce lactic acid, ATP use does not generate lactic acid, and running out of glucose would not directly cause lactic acid increase.

Answer:

b) The players are exercising so hard that anaerobic respiration produces a lot of lactic acid
