respiration

• Aerobic Respiration


  Oxidation of glucose complete, produces carbon dioxide and water, releases a relatively large amount of energy.
• Anaerobic Respiration

  Oxidation of glucose incomplete, produces varied products, releases a small amount of energy quickly, occurs in absence or shortage of oxygen.
• C6H12O6


  Glucose, a type of sugar that serves as the primary source of energy for most living organisms
• ATP

  Full Name: Adenosine Triphosphate What it Does: Stores and releases energy for cellular processes
• C2H5OH

  An ethanol molecule, a product of anaerobic respiration
• What is hemoglobin?

  A protein in red blood cells
• What role does hemoglobin play in the body?

  It transports oxygen throughout the body
• What is the structure of hemoglobin?

  • Composed of four protein subunits
  • Each subunit contains a heme group
  • Heme group has an iron atom at its center
  • Iron atom binds to oxygen
• How does hemoglobin function in oxygen transport?

  It binds oxygen in the lungs and carries it to tissues
• Where does oxygen bind to hemoglobin?

  In the lungs
• What is formed when oxygen binds to hemoglobin?

  Oxyhemoglobin
• What happens to hemoglobin in the tissues?

  It releases oxygen and picks up carbon dioxide
• What waste product does hemoglobin help transport back to the lungs?

  Carbon dioxide
• Why is hemoglobin important for red blood cells?

  • Carries large amounts of oxygen efficiently
  • Prevents poor oxygen dissolution in blood
  • Maintains blood pH by regulating carbon dioxide levels
• How does hemoglobin help maintain blood pH?

  By regulating carbon dioxide levels
