Chemical Change and Cellular Respiration

Front

What is the primary function of ATP in living organisms?

Back

ATP provides energy for cells.

Front

What is the balanced chemical equation for cellular respiration?

Back

6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy

Front

Which of the following is a product of cellular respiration?

Back

All of these are products of cellular respiration.

Front

Which molecule is known to store more chemical energy, ATP or glucose?

Back

ATP stores more chemical energy.

Front

Which organelle is primarily responsible for cellular respiration?

Back

Mitochondria.

Front

What are the main stages of cellular respiration?

Back

Glycolysis, Krebs cycle, and Electron Transport Chain.

Front

What is glycolysis and where does it occur?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, occurring in the cytoplasm.

Front

What role do mitochondria play in cellular respiration?

Back

Mitochondria are the sites where the Krebs cycle and Electron Transport Chain occur, producing ATP.

Front

What is the significance of oxygen in cellular respiration?

Back

Oxygen is the final electron acceptor in the Electron Transport Chain, allowing for the production of ATP.

Front

What are the end products of the Krebs cycle?

Back

The end products of the Krebs cycle are CO2, ATP, NADH, and FADH2.
