An athlete is training really hard and becomes dizzy and feels ill and weak. What could be the cause of this weakness, in relation to cellular respiration?

Dehydration.

Explanation:

Dehydration is the cause of this weakness, in relation to cellular respiration because in cellular respiration water is produces when the glucose molecules are broken down for the release of energy. In this process, our body temperature increases so our body removes heat from the body with the use of water which leads to dehydration and the athlete feels hard and becomes dizzy and feels ill and weak.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.

i believe the answer would be b. hope it : )
