Portage Learning Chem 210 - Module 7 Problem Set.A scientist uses the term flux regarding a biochemical pathway. What does flux mean? Flux is the rate of flow through a biochemical pathway. A particular pathway breaks down proteins into amino acids. Is this an anabolic or a catabolic pathway? Catabolic. This is degradation of a molecule. The acetyl group is connected to CoA to make Acetyl-CoA. A) What specific atom of CoA connects to the carbon atom on the acetyl group? B) What nucleotide base is part of CoA? A) Sulfur B) Adenine Both carbohydrates and lipids are broken down into Acetyl-CoA for further processing. What pathway does Acetyl-CoA go to next? Citric Acid Cycle (CAC) What is the “ETC” and what happens there? Electron transport chain. NADH is converted into ATP at the ETC. What is the sign (+ or -) of ΔG for the breakdown of ATP to ADP? Why is the sign important? (-). A negative means spontaneous, or favorable, and is able to power other processes. What molecule (FADH2, ATP, ADP, or CoA) is shown below?
