Cellular Respiration

What is the difference between aerobic and anaerobic respiration?

• Aerobic respiration occurs without oxygen and produces less ATP.

• Anaerobic respiration requires oxygen and produces more ATP.

• Aerobic respiration requires oxygen and produces more ATP.

• Anaerobic respiration occurs in the presence of oxygen and produces more ATP.

What is a reactant in cellular respiration?

• A substance that is consumed during the process, such as glucose or oxygen.

• A product that is formed after the process is complete.

• A catalyst that speeds up the reaction without being consumed.

• A waste product that is released after the process.

What is the overall equation for cellular respiration?

• C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

• C6H12O6 + 3O2 → 3CO2 + 3H2O + 2ATP

• C6H12O6 + 6O2 → 6CO + 6H2O + 6ATP

• C6H12O6 + 2O2 → 2CO2 + 2H2O + 4ATP

What is ATP and why is it important?

• ATP is a type of protein that helps in muscle contraction.

• ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

• ATP is a carbohydrate that stores genetic information.

• ATP is a lipid that forms the cell membrane.

What is the relationship between photosynthesis and cellular respiration?

• Photosynthesis produces energy, while cellular respiration converts energy into glucose.

• Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.

• Photosynthesis and cellular respiration are identical processes that occur in plants.

• Photosynthesis occurs in the mitochondria, while cellular respiration occurs in the chloroplasts.

What is the role of oxygen in cellular respiration?

• Oxygen is used to break down glucose into pyruvate.

• Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

• Oxygen is converted into carbon dioxide during glycolysis.

• Oxygen is not involved in cellular respiration.

Where does glycolysis occur?

• In the mitochondria of the cell.

• In the cytoplasm of the cell.

• In the nucleus of the cell.

• In the endoplasmic reticulum of the cell.

What is the electron transport chain?

• A series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to create a proton gradient for ATP synthesis.

• A process that occurs in the cytoplasm to break down glucose into pyruvate.

• A mechanism for DNA replication that involves the unwinding of the double helix.

• A type of cellular respiration that does not require oxygen.
