Back

Citric Acid Cycle.

Front

Where does the Krebs cycle take place in the cell?

Back

In the mitochondria.

Front

What is the primary function of the Krebs cycle?

Back

To generate energy through the oxidation of acetyl-CoA.

Front

What are the main products of the Krebs cycle?

Back

Carbon dioxide, ATP, NADH, and FADH2.

Front

How many carbon atoms are in the acetyl-CoA that enters the Krebs cycle?

Back

2 carbon atoms.

Front

What is the waste product of the Krebs cycle?

Back

Carbon dioxide.

Front

Is oxygen required for the Krebs cycle to occur?

Back

Yes, indirectly, as it is required for the electron transport chain which follows the Krebs cycle.

Front

How many ATP molecules are produced directly during one turn of the Krebs cycle?

Back

2 ATP molecules.

Front

What role do NADH and FADH2 play in cellular respiration?

Back

They carry electrons to the electron transport chain.

Front

What is the starting molecule for the Krebs cycle?

Back

Acetyl-CoA.
