food molecules; ATP

In fermentation, ______ produced by glycolysis is reduced, and ______ is regenerated, which allows glycolysis to continue to produce a small amount of ATP.

pyruvate; NAD+

What pathway of aerobic cellular respiration generates ATP by chemiosmotic phosphorylation?

electron transport chain

Select the molecules that are products of the Krebs cycle.

- ATP -NADH -Carbon dioxide - FADH2

Select all of the following that cause the difference between the theoretical and actual yields of ATP in aerobic respiration.

- ATP is sent transporting pyruvate and ADP into the mitchondrial matrix. - Protons leak across the inner mitochondrial membrane without using ATP synthase

Select all of the molecules that are reactants of glycolysis

- NAD + - Glucose

Select all of the following that are reactants of pyruvate oxidation during the "transition step" of cellular respiration.

- NAD+ - pyruvate

Select all of the following that are true of ATP synthesis.

- a phosphate group is added to ADP - requires an input of energy ( endergonic reaction)

Select all the food molecules that can be broken down into glucose monomers, which enter aerobic respiration at the beginning of glycolysis.

- glycogen - starch

Select all of the following that are products of the "transition step" in aerobic cellular respiration.

-CO2 - NADH Acetly CoA

Select all of the following that are products in the overall equation for aerobic respiration.

-CO2 (carbon dioxide) - ATP ( adenosine triphosphate)

Select all of the following steps of cellular respiration that generate ATP by substrate-level phosphorylation—that is, without a proton gradient.

-Krebs cycle - glycolysis

The oxidation of glucose during aerobic respiration yields ATP, NADH, and FADH2 molecules. In theory, the ATP yield during the electron transport chain is ______ molecules of ATP per NADH and ______ molecules of ATP per FADH2.

3;2

Match the term with the correct description concerning food and energy.

ATP- supplies power to almost all cellular activities requiring energy Photosynthesis- uses light energy to produce food in the form of glucose Cellular Respiration- converts the energy in food to an energy- carrying molecule

What product of pyruvate oxidation enters the Krebs cycle?

Acetyl CoA

Aerobic cellular respiration requires that ______ diffuses out of cells, and ______ diffuses into cells.

CO2;O2
