Cellular Respiration: Kreb's & ETC

Front

What is the starting molecule of the Kreb's Cycle?

Back

Pyruvate

Front

Where does the Kreb's Cycle take place in the cell?

Back

Matrix of mitochondria

Front

What is the primary function of ATP synthase?

Back

To produce ATP from ADP and inorganic phosphate.

Front

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

Back

Twice

Front

What is a waste product produced during the Kreb's Cycle?

Back

Carbon dioxide (CO2)

Front

What is the main purpose of cellular respiration?

Back

To convert biochemical energy from nutrients into ATP.

Front

What are the three main stages of cellular respiration?

Back

Glycolysis, Kreb's Cycle, and Electron Transport Chain (ETC).

Front

What is produced during glycolysis?

Back

2 ATP, 2 NADH, and 2 pyruvate molecules.

Front

What role do NADH and FADH2 play in cellular respiration?

Back

They act as electron carriers to the electron transport chain.

Front

What is the final electron acceptor in the electron transport chain?

Back

Oxygen (O2)
