BCH 361 CHEN EXAM 3 QUESTIONS WITH VERIFIED
ANSWERS
catabolic pathways - Answers - combust carbon fuels to synthesize ATP
Anabolic pathways - Answers - Use atp, nadph and smaller building blocks to
synthesize large biomolecules
Three stages of catabolism - Answers - 1] Digestion: breakdown of complex molecules
to their component building blocks
2] conversion of building blocks to acetyl- CoA (or other simple intermediates)
3] Metabolism of acetyl-CoA to CO2 and formation of ATP
Phosphoryl-transfer potential - Answers - amount of free energy liberated when a
phosphate group is released through hydrolysis
Creatine phosphate - Answers - Can regenerate ATP from ADP
NADP+ - Answers - Electron carrier during anabolism. Receives 2 electrons and H+
(and becomes reduced)
Coenzyme-A - Answers - carrier of acyl groups
Vitamin B3 (Niacin) - Answers - NAD+
Vitamin B2 (Riboflavin) - Answers - FAD
NAD+ and FAD - Answers - Electron carriers for catabolism
Catabolism - Answers - Energy-yielding metabolism
Anabolism - Answers - Biosynthetic metabolism
Aerobic metabolism creates - Answers - Acetyl CoA
Anaerobic metabolism creates - Answers - Lactate
Three ways of metabolic regulation - Answers - amounts of enzymes, catalytic activity of
enzymes, and accessibility of substrates
Energy status - Answers - energy charge and phosphorylation potential
