2. Pyruvate Oxidation

Question 1

What is pyruvate oxidation sometimes nicknamed

Answer 1

“The bridge”

Question 2

If pyruvate oxidation part of glycolisis or the krebs cycle

Answer 2

Neither, it is a bridge between the two pathways

Question 3

Whats the purpose of pyruvate oxidation

Answer 3

Take pyruvate from cytoplasm into mitchondria by shuttling pyruvate down an organelle

Question 4

Whats the organelle pyruvate gets shuttled down called

Answer 4

The mitochondrion

Question 5

How does the pyruvate molecules move through the mitochondrion

Answer 5

A small group of enzymes in the mitochondria help more it

Question 6

Where does glycolisis and the krebs cycle take place

Answer 6

Glycolisis - cytoplasm
Krebs cycle - mitochondria

Question 7

Explain the first step of pyruvate oxidation

Answer 7

Pyruvate releases CO2 to form Acetate

Question 8

Explain the second step of pyruvate oxidation

Answer 8

Acetate is oxidiced and gives elections to H+ ions to make 2 NAD+ — 2NADH

Question 9

Explain the third step of pyruvate oxidation

Answer 9

Acetate is combined with CoA to produce 2 Acetyl CoA molecules
