Cardiac muscle cells need to generate significant amounts of ATP to allow for constant contractile activity. As a result, they primarily depend upon beta-oxidation of fatty acids, which has a higher energy yield than the catabolism of glucose. What would be the ATP yield for beta-oxidation of a hypothetical 10-carbon fatty acid?
A. 32 ATP B. 35 ATP C. 50 ATP D. 62 ATP E. 65 ATP Clarify Question What is the key concept addressed by the question? What type of thinking is required? Gather Content What do you already know about cellular respiration and beta-oxidation of fatty acids? How do these molecules plug into the process of cellular respiration? What other information is related to the question? Choose Answer Do you have all necessary information to determine the ATP yield from beta-oxidation of a 10-carbon fatty acid? Reflect on Process Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
