1. A, because organisms need carbohydrate, vitamins, and minerals and other nutrients to gain energy and proteins to live and to continue metabolism. B, The amount of energy stored in macromolecules varies because their chemicals structures, and there for the energy contain in their chemical differ. 2. 6O2 + 62H1206 -> 6O2 + 6H2O + Energy

B The process of cellular respiration provides the energy a cell needs to carry processes, which in turn control the cell’s internal conditions.

3. Photosynthesis “deposits” energy, used carbon dioxide and water, and produces oxygen and glucose. By cellular contrast, cellular respiration “withdraws” energy, uses oxygen and glucose and produces carbon dioxide and water. b. The chemical energy of glucose is stored in the body as (ATP), whenever this energy is needed. It can directly be taken and consumed by the body.

In savings account the same idea, u save your money there, and anytime u need money; u can take it from your account directly without waiting and spent it. 4. An ATP-generating metabolic process that occurs in nearly all living cells in which glucose is converted in a series of steps to pyruvic acid. Pg. 260

1. At the end of glycolysis, each molecule of glucose has yielded 2 molecules of pyruvate, 2 molecules of NADH, and a net of 2 molecules of ATP.

Energy in the form of ATP (adenosine tri-phosphate). Glycolysis takes molecule of glucose and turns it into energy the body can use.

Output
Glycolysis converts one molecule of glucose into two molecules of pyruvate, along with "reducing equivalents" in the form of the coenzyme NADH.

The global reaction of glycolysis is:
Glucose + 2 NAD+ + 2 ADP + 2 Pi → 2 NADH + 2 pyruvate + 2 ATP + 2 H2O + 2 H+ Therefore, for simple fermentations, the metabolism of 1 molecule of glucose has a net yield of 2 molecules of ATP. Cells performing respiration synthesize much more ATP but this is not considered part of glycolysis. Eukaryotic aerobic...
