Metabolic Pathways

Chapter 26

Metabolic Pathways – Ch. 261. List three reasons why the hydrolysis of

ATP into ADP and phosphate is so thermodynamically favorable:

Metabolic Pathways – Ch. 262. Why is the rate of nucleophilic attack on

ATP (ex hydrolysis) significantly faster in an enzyme?

Metabolic Pathways – Ch. 263. An enzyme that catalyzes

phosphorylation is called a _______________. Compare and contrast the 3 possible mechanisms for phosphorylation of a fatty acid in order to attach it to coenzyme A.

Metabolic Pathways – Ch. 264. List and describe the four stages of

catabolism:

Metabolic Pathways – Ch. 26

Metabolic Pathways – Ch. 265. For every one molecule of glucose that

undergoes glycolysis__________ molecules of pyruvate, __________ ATP molecules and ____________ NADH.

Metabolic Pathways – Ch. 266. What causes lactic acid build up?

Metabolic Pathways – Ch. 267. Before pyruvate can enter the citric acid

cycle it must be converted to _________________ by 3 enzymes and the 5 coenzymes ___________, ______________,_____________,_____________ and _______________ in the pyruvate dehydrogenase system

Metabolic Pathways – Ch. 268. In the first step of catabolism; fats are

hydrolyzed into ____________ and ______________. Catabolism of 1 molecule of palmitic acid (fatty acid with 16 carbons) produces ___________ acetyl CoA molecules______________ FADH2 molecules and ___________ NADH molecules.

Metabolic Pathways – Ch. 26

Metabolic Pathways – Ch. 269. The overall reaction for the citric acid

cycle is ______________________________________ which produces ______________ molecules of ATP________________molecules of NADH and _________________molecules of FADH2

for every molecule of acetyl CoA.

Metabolic Pathways – Ch. 2610. Stage 4 of catabolism is _________________________

in which 1 molecule of NADH produces ___________ molecules of ATP and 1 molecule of FADH2 produces ____________ molecules of ATP. Therefore for each molecule of acetyl CoA that enters the citric acid cycle ____________ molecules of ATP are produced. For every 1 molecule of glucose that is catabolized ___________ molecules of ATP are produced.For every 1 molecule of palmitic acid that is catabolized_______ molecules of ATP are produced.

Metabolic Pathways – Ch. 2611. What is the majority type of reactions in

the anabolic pathways?
