How many NET ATPs would theoretically need to be used to store excess glucose as laurate...
How many NET ATPs would theoretically need to be used to store excess glucose as laurate (C12:0) (i.e., catabolize the glucose to acetyl-CoA and then anabolize to laurate)? Since there are 12 carbons in laurate and each glucose can be converted to two acetyl-CoAs, assume that you'll begin with 3 glucoses. Also, assume you already have sufficient oxaloacetate in the mitochondria to pair with the acetyl-CoA. Show the basic outline of the process. Indicate where each ATP, NADH, etc. is made or used. (For simplicity,...

A fatty acid composed of 20 carbon atoms undergoes β‑oxidation. How many acetyl CoA, FADH2, and NADH does β‑oxidation of this fatty acid generate? (answer is 10 acetyl CoA, 9 FADH2, 9 NADH) Calculate the net ATP generated by the β‑oxidation of the 20‑carbon fatty acid. Assume that each FADH2 generates 1.5 ATP and each NADH generates 2.5 ATP. number of ATP molecules: ??????
