Citric Acid Cycle questions a) Since carbons arrive from glucose via acetyl CoA, what carbons from glucose are in Acetyl CoA? Number them in Acetyl CoA using the original number from glucose. b) Are any carbons from acetyl CoA removed as CO2 during the first "turn" of the citric acid cycle? c) What glucose carbon(s) is (are) the first to be removed as CO2 in the citric acid cycle?

A) Acetyl coA is made from pyruvate in the [ Select ] ["mitochondrial matrix", "cytoplasm", "", ""] by [ Select ] ["pyruvate dehydrogenase", "succinate dehydrogenase"] complex. In this process, the acetyl group is moved between enzymes within the complex by the [ Select ] ["lipoamide", "TPP"] . The [ Select ] ["dihydrolipoyl transacetylase", "pyruvate dehydrogenase component"] is the enzyme in which acetyl coA is actually formed. The [ Select ] ["FADH2", "lipoamide"] in the dihydrolipoyl dehydrogenase donates two electrons to...

Starting with Acetyl-CoA in the mitochondrial matrix, show how a molecule of acetyl-CoA may get incorporated into a molecule of phosphatyidylserine in the plasma membrane. You should summarize the pathways involved into the critical steps involved. You do NOT need to show every reaction and/or enzyme. You can present your summarizing note in any form like a table, diagram, or outline, do NOT describe it in just words. Your pathway should have a minimum of six steps. Label at least...

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,...
