1) why would temperature affect respiration rates? what is goingon at the cellular level that could be impacted by either anincrease or a decrease in the temperature in which an organism isfound?


2) other than temperature, what other environmental conditionscould affect the rate of respiration? describe how each would havean impact?

Question 6

Select one answer.

10 points

One way to explain how cellular respiration and photosynthesis relate to each other is to say that:

Plant cells use the oxygen produced by respiration for photosynthesis.

The oxygen produced by photosynthesis, once released to the environment, is the oxygen able to be used as the electron acceptors for cellular respiration.

Cellular respiration is a series of reduction reactions while photosynthesis is a series of oxidation reactions.

The two processes are not related.

The use of oxygen by plants contributes to the greenhouse effect.
