Answer Selected Answer: 38 Correct 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 37 0 out of 1 points The products of fermentation of bacteria can be used to produce Answer Selected Answer: lactose used in making wine. Correct Answer: lactose used in making yogurt. Response Feedback: Lactose is a product produced by bacteria and can be used in making yogurt, a fermented milk product. Question 38 1 out of 1 points Susan suffered from a heart attack. When the doctors tested the heart muscle they found that she had an increased ratio of lactic acid to pyruvic acid in her heart. What does this say about the availability of oxygen in her heart muscle cells? Answer
Selected Answer: The heart cells had not received adequate oxygen supply. Correct Answer: The heart cells had not received adequate oxygen supply. Response Feedback: Lactic acid is an indication that lactic acid fermentation is occurring in muscle cells. Lactic acid fermentation occurs only in the absence of oxygen; thus, the heart cells may not have been receiving enough oxygen, a factor that could contribute to the occurrence of a heart attack. The level of lactic acid could be measured in certain parts of the heart as an indication of risk of heart attack. Question 39 0 out of 1 points What type(s) of organisms does cellular respiration occur in? Answer Selected Answer: autotrophs Correct Answer: All answers given are correct. Response Feedback: Autotrophs produce their own food, yet they still need to go through cellular respiration. During cellular respiration food is broken down and the energy released is captured and stored in ATP molecules. Current Location 1. Principles of Biology (BIO102.SP13.ZB) 2. Assignments 3. ... 4.
