Question 1

Glycolysis?

Answer 1

series of reactions that metabolizes one molecule of glucose to two molecules of pyruvate with the net production of 2 ATP

Question 2

Is glycolysis anaerobic or aerobic?

Answer 2

anaerobic

Question 3

Pyruvate can be further processed anaerobically to what?

Answer 3

lactate or ethanol

Question 4

Under aerobic conditions pyruvate can be oxidized to what?

Answer 4

CO2

Question 5

Gluconeogenesis?

Answer 5

pyruvate and lactate are salvaged to synthesize glucose

Question 6

What can glycolysis and gluconeogenesis not occur at the same time? How?

Answer 6

the highly exergonic, irreversible steps of glycolysis are bypassed in gluconeogenesis so that they are reciprocally regulated; because if both sets of reactions were highly active at the same time, the net result would be the hydrolysis of four nucleoside triphosphates (2 ATP and 2 GTP) per reaction cycle

Question 7

What is glucose generated from?

Answer 7

dietary carbohydrates
