Answer:
Respiration
Explanation:
Food energy is chemical energy that animals (including humans) derive from food through the process of cellular respiration. Cellular respiration may either involve the chemical reaction of food molecules with molecular oxygen (aerobic respiration) or the process of reorganizing the food molecules without additional oxygen (anaerobic respiration).
I think its B but I'm not sure .. sorry
hi <3
changes in the enzyme's shape would decrease its ability to function as this would change the active site of the enzyme, meaning it is harder for it to carry out its job.
this is why we try to keep enzymes in their optimum environmental conditions so they can function their best
hope this helps :)
