Biology 1.6 - Respiration

• Respiration equation?

  glucose + oxygen --> carbon dioxide + water + energy
• What is ATP?

  The high-energy molecule produced during respiration
• What is ATP made of?

  One adenosine molecule, with three inorganic phosphates.
• How does ATP release energy?

  Energy is released when the bond between the 2nd and 3rd phosphate bond is broken.
• What is the energy release in ATP used for?

  Cellular activities such as; muscle contraction, synthesis and other chemical reactions.
• Where would you find ATP?

  The cytoplasm
• What is aerobic respiration?

  Respiration when oxygen is present
• What is stage one of respiration called?

  Glycolysis
• What happens during glycolysis?

  A glucose molecule is broken down into 2 molecules of pyruvate.
• Where does glycolysis occur?

  Cytoplasm
• Does glycolysis need oxygen?

  No
• How many ATP are produced in glycolysis?

  2 ATP
• What is stage two of respiration called?

  The breakdown of pyruvate
• What happens during the breakdown of pyruvate?

  The pyruvate made in glycolysis is broken down using oxygen - into carbon dioxide and water.
• Where does the breakdown of pyruvate happen?

  Mitochondria
• What does anaerobic mean?

  Without oxygen
