7. In the ketone body pathway, both acetoacetate and B-hydroxy butyrate are produced andbecome additional fuel molecules for the organism.a. Define where these molecules are produced (both tissue type and location in the cell)and what tissue they "feed".b. Of these two molecules, which one is considered slightly better in delivering moreenergy to the target tissue? Why?c. How does acetone, another ketone body, participate in delivering fuel to targettissue?d. If acetoacetate decarboxylase enzyme was mutated and became inactive (zeroenzyme activity), how would this affect the ketone pathway during these conditions:į. immediately after a meal,ii. under starvation conditions,iii. during unchecked (not being treated for) type-1 diabetes.

Since we only answer up to 3 sub-parts, we’ll answer the first 3. If you need help with other sub…

Answered: 7. In the ketone body pathway, both…

7. Why are electron carriers (NAD+/NADH and FAD/FADH2) so important in the process of cellular respiration? a) They deliver electrons to the ETC, which in turn sets up chemiosmosis, where most of the ATP is generated. b) They separate the electrons from the protons so that the protons can be moved out of the mitochondrion. c) NADH and FADH2 are major components of the ETC, so without them, there would be no ETC in the cell. d) The electrons that they carry are able to directly phosphorylate ADP in order to generate the bulk of ATP in the cell. e) They transport protons across the mitochondrial membrane.
