1
New cards

Purpose

to obtain the rest of the energy from the pyruvate and to get the electrons

2
New cards

What happens to the pyruvate

It is oxidized as a CO2 molecule and is removed and a coenzyme is added to form Acetly-CoA

3
New cards

Inputs

2 pyruvate

3 NAD+

FAD

4
New cards

Outputs

1 ATP (per turn)

2 CO2 (per turn)

3 NADH (per turn)

1 FADH2 (per turn)

New cards

How many turns is the Krebs cycle

Turns twice for every one glucose molecule

6
New cards

Why it turns twice

Glycolysis breaks down one 6-carbon sugar into two 3-carbon sugar (2 pyruvate)

Each pyruvate in converted into an acetyl-CoA molecule (2-carbon sugar)

One glucose produces 2 acetyl-CoA, so the Krebs cycle must run once for each acetyl-CoA
