Metabolism

• Why is Acetyl-CoA important in cellular respiration?

  It carries two carbon atoms to the Krebs cycle.
• What is the active site of an enzyme?

  It is the part of the enzyme where the substrate binds.
• What does ATP stand for?

  Adenosine Triphosphate
• What is aerobic respiration?

  It is respiration that occurs in the presence of oxygen.
• What is anabolism?

  It is the process of building up complex substances from simpler ones.
• What does anaerobic mean?

  It refers to growing or metabolizing only in the absence of molecular oxygen.
• What is an apoenzyme?

  It is the protein portion of an enzyme that requires a co-factor to function.
• What are the main differences between aerobic and anaerobic respiration?


  • Aerobic: Requires oxygen, produces more energy
  • Anaerobic: Occurs without oxygen, produces less energy
• What is the significance of anaerobic respiration in certain organisms?

  • Allows survival in low-oxygen environments
  • Produces energy without oxygen
  • Important for certain metabolic processes
• What is the significance of aerobic respiration in living organisms?

  • Produces more energy than anaerobic respiration
  • Essential for cellular metabolism
  • Supports growth and development
• What is the significance of studying anaerobic respiration?

  • Important for understanding energy production without oxygen
  • Relevant for certain organisms in low-oxygen environments
  • Provides insights into metabolic processes
