Cellular Respiration

What organelle is responsible for producing ATP through cellular respiration?

• Chloroplast

• Endoplasmic Reticulum

• Mitochondrion

• Golgi Apparatus

In which part of the cell does glycolysis occur?

• In the mitochondria.

• In the nucleus.

• In the cytoplasm.

• In the endoplasmic reticulum.

Where is most energy released during respiration produced?

• Cytoplasm

• Nucleus

• Mitochondria

• Ribosomes

What is produced as a byproduct of cellular respiration?

• Oxygen and glucose.

• Carbon dioxide and water.

• Nitrogen and ammonia.

• Lactic acid and ethanol.

What is the process called in which a cell converts glucose into usable energy?

• Photosynthesis

• Cellular respiration

• Fermentation

• Glycolysis

What is the chemical equation for cellular respiration?

• C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

• C6H12O6 + 3O2 → 3CO2 + 3H2O + 2ATP

• C6H12O6 + 6O2 → 6CO + 6H2O + 6ATP

• C6H12O6 + 6O2 → 6C + 6H2O + 6O2

What is the role of oxygen in cellular respiration?

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

• Oxygen is used to produce glucose during photosynthesis.

• Oxygen is a byproduct of cellular respiration.

• Oxygen helps in the breakdown of fatty acids.

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

• It produces electron carriers (NADH and FADH2) for the electron transport chain.

• It generates ATP directly through substrate-level phosphorylation.

• It converts glucose into pyruvate before entering the mitochondria.

• It synthesizes fatty acids for energy storage.

What is anaerobic respiration?

• A type of respiration that occurs with oxygen, producing more ATP.

• A type of respiration that occurs without oxygen, producing less ATP.

• A type of respiration that occurs only in plants, producing glucose.

• A type of respiration that occurs in the presence of carbon dioxide, producing energy.

Do both plant and animal cells use respiration?

• Yes, both plant and animal cells use respiration.

• Only plant cells use respiration.

• Only animal cells use respiration.

• Neither plant nor animal cells use respiration.
