Cell Respiration Flashcard

Front

What is the role of ATP synthase in cellular respiration?

Back

ATP synthase is an enzyme in the electron transport chain (ETC) responsible for generating ATP molecules from ADP and inorganic phosphate during oxidative phosphorylation.

Front

Which molecule is considered a fully charged battery in cellular respiration?

Back

ATP is considered a fully charged battery because it has three phosphate groups, and breaking the bonds among them releases energy.

Front

How is energy released from ATP?

Back

Energy is released from ATP by removing the third phosphate group, which converts ATP to ADP.

Front

What is lactic acid fermentation and when does it occur?

Back

Lactic acid fermentation occurs in muscles during intense exercise when oxygen levels are low, leading to the production of lactic acid.

Front

What are the main products of cellular respiration?

Back

The main products of cellular respiration are energy (ATP), water, and carbon dioxide.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the function of glucose in cellular respiration?

Back

Glucose serves as the primary fuel source for cellular respiration, providing the energy needed for ATP production.

Front

What is the significance of the electron transport chain (ETC)?

Back

The electron transport chain is crucial for ATP production, as it transfers electrons and pumps protons to create a gradient used by ATP synthase.

Front

What is fermentation and why is it important?

Back

Fermentation is a metabolic process that allows cells to generate energy without oxygen, important for survival in anaerobic conditions.

Front

What is the chemical equation for cellular respiration?

Back

The chemical equation for cellular respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.
