Krebs Cycle

Front

Where does the Krebs cycle take place?

Back

Mitochondrial Matrix

Front

What is the waste product produced during the Krebs cycle?

Back

Carbon Dioxide

Front

Acetyl-CoA is joined up to a __________ to form __________.

Back

4 carbon compound; citric acid

Front

What does the initial reaction of the Krebs cycle produce?

Back

CO₂, acetyl-CoA, and NADH

Front

For the two pyruvates that enter from glycolysis, what does the Krebs cycle yield?

Back

2 ATP, 8 NADH, and 2 FADH₂

Front

What is the main purpose of the Krebs cycle?

Back

To produce energy carriers (NADH and FADH₂) and CO₂ from the oxidation of acetyl-CoA.

Front

What are the main products of one turn of the Krebs cycle?

Back

3 NADH, 1 FADH₂, 1 ATP, and 2 CO₂.

Front

What role does NADH play in cellular respiration?

Back

NADH carries electrons to the electron transport chain for ATP production.

Front

What is the significance of the citric acid in the Krebs cycle?

Back

Citric acid is the first product formed in the cycle and is crucial for the continuation of the cycle.

Front

How many times does the Krebs cycle turn for each glucose molecule?

Back

Twice, as each glucose molecule produces two pyruvate molecules.
