AP Biology - Cellular Respiration

Front

What is the primary difference in energy yield between fermentation and aerobic respiration?

Back

Aerobic respiration results in more energy than fermentation.

Front

What is the reactant molecule in the process of Glycolysis?

Back

Glucose is the reactant of Glycolysis.

Front

Write the correct equation for cellular respiration.

Back

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

Front

Where does the Electron Transport Chain (ETC) occur in the cell?

Back

The Electron Transport Chain occurs across the inner mitochondrial membrane.

Front

What are the folds in the inner mitochondrial membrane called that increase the surface area for the ETC?

Back

The folds are called cristae.

Front

Define oxidation in the context of cellular respiration.

Back

Oxidation is the loss of electrons.

Front

What is the role of oxygen in aerobic respiration?

Back

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

Front

What are the end products of glycolysis?

Back

The end products of glycolysis are 2 pyruvate, 2 ATP, and 2 NADH.

Front

What is the function of ATP in cellular respiration?

Back

ATP serves as the primary energy currency of the cell, providing energy for various cellular processes.

Front

What is the significance of the Krebs cycle in cellular respiration?

Back

The Krebs cycle produces electron carriers (NADH and FADH2) that are used in the electron transport chain.
