Acetate produced in ethanol metabolism can be transformed into acetyl-COA by the acetyl thiokinase reaction: Acetate+ATP+CoASHacetyleCoA+AMP+PPiAcetyle-CoA then can enter the citric acid cycle and undergo oxidation to 2 CO2by this route, assuming oxidative phosphorylation is part of the process? (Assume all reactions prior to acetyl-CoA entering the citric acid cycle occur outside the mitochondrion). Per carbon atom, which is a better metabolic fuel, ethanol or glucose?

TRUE or FALSE?arrow_forwardThe same reactions that were seen in the process of converting pyruvate to acetyl-S-CoA, occur in step ____ of the citric acid cycle as ____________ is converted to _________________.arrow_forwardFatty acid oxidation for energy yield occurs in the mitochondrial matrix, and for palmitate as one example, generates [FADN2, NADH, and Acetyle-CoA or FADH, GTP, and NADPH] , all of which can be converted to ATP (108 of them to be exact) via oxidative phosphorylation. This is a [greater or smaller] yield of ATP per carbon atom compared to glucose. Ketogenesis is a process where acetyl-CoA (including that from breakdown of fatty acids) is converted to ketone bodies under conditions where carbohydrates are [in excess or liminting] . Acetoacetate and D-beta-hydroxybutyrate are delivered from liver to the blood stream where they provide energy for [cardiac and skeletal muscle as well as brain or synthesis of glycogen] . [Insulin or glucagon] promotes ketogenesis by stimulating fatty acid export from adipose tissue.arrow_forward
