Glucose?

Question 16

GLycolysis is the pathway for metabolizing the preferred macronutrient fuel of most cells. TF

Answer 16

True

Question 17

Glycolysis involves of the following reactions: An oxidation releasing carbon dioxide. TF

Answer 17

False: releases lactate or ethanol

Question 18

The enzyme that accomplishes pyruvate oxidation is allosterically regulated. TF

Answer 18

True: PFK enzyme

Question 19

In cells that can do fermentation, why would they do fermentation?

Answer 19

Anaerobic (conditions)

Question 20

Which of of the following compounds is an allosteric regulator of both a kinase and a phosphorylase?

Answer 20

Fructose-2,6-biphosphate: «&laquo_space;quantity in the cell decides if the cell is going to perform glycolysis or gluconeogenesis. This is acheived by binding FBP-1 (a phosphorylase) and PFK-1(a kinase).
