AP Biology - Cellular Respiration

Front

What is the main process that contributes to the release of CO₂ during cellular respiration?

Back

The Citric Acid Cycle (Krebs Cycle) is the largest contributor to the release of CO₂.

Front

Why is ATP considered the most significant energy-carrying molecule?

Back

ATP has different bond energy between its phosphate groups, allowing it to store and release energy efficiently.

Front

What does the phosphorylation of ADP indicate?

Back

ADP is being converted into ATP.

Front

How is cellular respiration related to photosynthesis?

Back

Cellular respiration is the reverse reaction of photosynthesis.

Front

What does a negative delta G indicate about a reaction?

Back

The reaction will release more energy than was needed to initiate it.

Front

What are the main stages of cellular respiration?

Back

Glycolysis, the Citric Acid Cycle, and Oxidative Phosphorylation.

Front

What is glycolysis and where does it occur?

Back

Glycolysis is the process of breaking down glucose into pyruvate, occurring in the cytoplasm.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process of ATP production that occurs in the mitochondria, using the energy from electrons transferred through the electron transport chain.

Front

What is the net gain of ATP from glycolysis?

Back

The net gain of ATP from glycolysis is 2 ATP molecules.
