Cellular respiration . Group of answer choices releases carbon dioxide and water results in a net consumption of energy involves a net consumption of water represents a decrease in entropy requires the green pigment chlorophyll

Cellular respiration releases C02 and water. This process leads to production of energy as ATPs. The objective is to extract the energy trapped in glucose and other metabolites. It  begins in the cytoplasm and ends in the mitochondrial of cells.  Since it involves liberation of energy as a spontaneous reaction, it has a positive entropy. It does not involves the use of Chlorophyll.

C02 and  water  as byproducts are given out during Kreb'scycle.

Explanation:

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

the correct answer is:

a population changes in response to a change in the environment.
