Afox chases a rabbit. which process causes the production of most of the energy the fox uses to run?

a. the calvin cycle
b. electron transport
c. the krebs cycle
d. glycolysis

Answer;

B. Electron Transport

Explanation;

-The electron transport chain is the final stage of aerobic respiration leading to the forming of ATP in the inner membrane of the mitochondrion. The emergent picture is that of coupled reactions through five protein structures associated with that inner membrane.

-Electron carriers are reduced during glycolysis and the citric acid cycle to NADH + H+ and FADH2. These carriers then donate electrons and protons to the electron carrier proteins of the electron transport chain. The final electron acceptor is oxygen. Together with oxygen, electrons and protons form molecules of water.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
