Cellular respiration is a series of complicated reactions. some of the enzymes that are necessary for the reactions to take place effectively are not produced by the body and must be eaten in a person’s diet. which answer correctly explains what happens when a person's diet lacks the necessary enzymes for cellular respiration?
a. the production of atp will increase as the enzyme decreases.
b. the cellular respiration reactions will use another available enzyme.
c. the cellular respiration reaction rate that uses the missing enzyme will increase.
d. the cell's energy level will diminish as the enzyme decreases.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
