Instructions Question 1 0.5 out of 0.5 points How many molecules of C 2 acetyl group are produced from six molecules of glucose 6 C 6 H 12 O 6 during aerobic respiration? Answer

Selected Answer: 12 Response Feedback: Each molecule of glucose produces 2 molecules of C 2 acetyl groups. Six molecules of glucose would therefore produce 12 C 2 acetyl groups. Question 2 0.5 out of 0.5 points What molecule most directly provides the energy you need for your muscles to contract? Answer Selected Answer: ATP Response Feedback: ATP molecules proved the energy needed for your muscles to contract. ATP molecules are produced during cellular respiration. Question 3 0 out of 0.5 points A family took their newborn to the doctor. They were worried something was wrong because she seemed to be in constant pain. The baby had large amounts of lactic acid accumulating in his muscles cells. Doctors figured out that the child had a rare disease in which mitochondria are missing from skeletal muscle cells. Which of the following statements explains what they found? Answer Selected Answer: The muscle cells can not split glucose into pyruvic acid. Response Feedback: Lactic acid fermentation occurs in normal animal muscle cells when there is a lack of oxygen. In this case lactic acid fermentation would occur because even if there wasn't a lack of oxygen the organelle in which cellular respiration take place in, mitochondria are absent.

Question 4 0.5 out of 0.5 points The number of ATP produced during cellular respiration from one glucose molecule is ________. Answer Selected Answer: 38 Response Feedback: The electron transport chain produces a maximum of 34 ATP, and the maximum total is 38 ATP. Some cells, however, produce only 36 ATP per glucose or even less. Question 5 0.5 out of 0.5 points The cristae of a mitochondrion are critical ________. Answer Selected Answer: both as a site for the electron transport chain and creating a space for concentration of H + Response Feedback: The cristae of mitochondria contain an ATP synthase complex that allows H1 to return to the matrix. The flow of H1 through the ATP synthase complex brings about a conformational change, which causes the enzyme ATP synthase to synthesize ATP from ADP+ P. ATP leaves the matrix by way of a channel protein.
