3. Energy & Cell Processes

Sports physiologists at an Olympic training center wanted to monitor athletes to determine at what point their muscles were functioning anaerobically. They could do this by checking for a buildup of which of the following compounds?

Which of the following is a distinction between cellular respiration and fermentation?a. the transfer of from intermediate substrates to ADPb. the movement of H+ across a membrane down its concentration gradientc. the splitting of glucose into two molecules of pyruvated. electrons moving through the electron transport chain

In which of the following is the first molecule becoming reduced to the second molecule?a. pyruvate → acetylCoAb. pyruvate → lactatec. glucose → pyruvated. NADH + H+ →NAD+ + 2H

Which of the following correctly describe the fermentation pathway? Select True or False for each statement.T/FIt includes a reaction that oxidizes NADH to NAD+.T/FIt synthesizes ATP by substrate-level phosphorylation.T/FIt includes a reaction that reduces NAD+ to NADH.T/FIt synthesizes electron acceptors, so that cellular respiration can continue.
