What is the function of some cofactors in relation to enzymes?

• Cofactors are only involved in the transport of enzymes.
• Cofactors enhance enzyme activity and stability, and may participate in the reaction.
• Cofactors are unnecessary for enzyme function and stability.
• Cofactors inhibit enzyme activity and reduce stability.

What is formed when oxygen acts as the final electron carrier?

• Oxygen acts as the final electron carrier in cellular respiration, leading to the formation of water (H2O) as a byproduct.

• Oxygen acts as the final electron carrier in cellular respiration, leading to the formation of carbon dioxide (CO2) as a byproduct.

• Oxygen acts as the final electron carrier in cellular respiration, leading to the formation of glucose (C6H12O6) as a byproduct.

• Oxygen acts as the final electron carrier in cellular respiration, leading to the formation of oxygen gas (O2) as a byproduct.
