Question 0

What is the committed step in glycolysis?

Answer 0

PFK

Question 1

Glycolysis

Answer 1

In the cytosol. Makes 2 ATP and 2 NADH and from that we have 2 pyruvates

Question 2

A decrease in NAD+ does what

Answer 2

inhibits glycolysis. That’s why fermentation occurs

Question 3

Pyruvate dehydrogenase complex (PDC)

Answer 3

Located in the mitochondrial matrix. Each pyruvate becomes a 2 carbon molecule

Releases 1 co2 and 1 NADH per pyruvate. Remember there are two

Question 4

Krebs cycle

Answer 4

You make 2 co2, 3 NADH, 1 FADH, and 1 GTP per glucose.

This all occurs in the mitochondrial matrix.

Question 5

Electron transport chain occurs where?

Answer 5

Inner me membrane space the most impermeable place. Also protons are pumped out of the matrix into the intermembrane space, which is continuous with the outer membrane which is also porous

Question 6

Glycogenolysis

Answer 6

Glycogen breakdown. Where glycogen is a polymer of glucose found in muscle and liver cells. It’s also the main form of carbohydrate storage in cells. When we have low blood sugar we have high glycogenolysis

Question 7

Gluconcogenesis

Answer 7

Low glucose from diet and liver and low glucose occurs in the liver.

Question 8

What is the backbone of a protein?

Answer 8

The peptide bonds within the primary structure. The r group is the variable portion.
