CEM 311 Lecture Notes - Lecture 32: Acetyl-Coa, Metabolic Pathway, Cellular Compartment
Document Summary
Organisms using organic compounds as a carbon source and oxidation-reduction reactions as an energy source are? (hint: keywords: carbon source and oxidation- reductions reactions) Cells maintain tight and separate regulation of catabolic and anabolic pathways. Completing anabolic and catabolic pathways often are located in different cellular compartment. The enzymes of a metabolic pathway may exist as? a. ) physically separate, soluble entities b. ) weakly bound together in functional complexes (metabolons) c. ) strongly bound together in multienzyme complexes d. ) membrane-bound multienzyme systems. Molecules are degraded to intermediates (metabolites) such as pyruvate and acetyl- Different by at least one enzyme step to allow for independent regulation. The products of stage 2 of catabolism are common products, such as pyruvate and acetyl-coa, which equals atp and nadh. The subtrates for anabolism are atp and nadph. Which vitamin or coenzyme functions in the decarboxylation of alpha-keto acids? thiamin pyrophosphate, vitamin b1. Which vitamin or coenzyme functions in reactions involving amino acids? pyridoxal phosphate, vitamin b6.
