During Kreb's, the pyruvate enters the mitochondria and loses a molecule of CO2 and becomes

• acetyl CoA
• citric acid
• glucose
• ATP

Citric acid is formed when

• acetyl CoA joins a 4 carbon molecule
• carbon dioxide is formed
• pyruvate joins ATP
• ATP become ADP

How many times does Kreb's Cycle turn for each molecule of glucose?

• twice
• once
• three times<br />
• it does not turn

Inputs of Kreb's Cycle?

• pyruvic acid
• ATP, NADH
• ATP, NADH, FADH
• CO2

Outputs of Kreb's?

• all are correct
• CO2
• NADH
• FADH2
• ATP

How much ATP does the Electron Transport Chain produce?

• 34 average
• 38 average
• 4 average
