if oxygen supplies are depleted during exercise, the body will use anaerobic respiration to produce the energy being demanded. what effects might this have on the athlete? explain your answer.

Intense pain in the muscle is caused due to production of lactic acid (as a result of anaerobic respiration)

Explanation:

When an athlete exercises intensely, the muscles carry out lactic acid fermentation in the absence of oxygen.  

Lactic acid fermentation is a form of anaerobic respiration in which phosphate and glucose with in the muscles is broken down to produce energy and a byproduct, lactic acid.  

Lactic acid causes intense pain and fatigue in the muscles due to which muscles can not rely on anaerobic respiration for a longer period of time.  

the calvin cycle has three stages. in stage 1, the enzyme rubisco incorporates carbon dioxide into an organic molecule. in stage 2, the organic molecule is reduced. in stage 3, rubp, the molecule that starts the cycle, is regenerated so that the cycle can continue
