Topic 1 Energy and Metabolism

• What is cellular respiration?

  Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP.
• What are the types of cellular respiration?

  Aerobic and anaerobic.
• What is Glycolysis?

  Glycolysis is an anaerobic process that occurs in the cytoplasm. Converts glucose into 2 pyruvate molecules, producing small amounts of ATP and NADH in the process.
• What is aerobic respiration?

  Requires energy and occurs in the mitochondria. Glucose is broken down completely to produce carbon dioxide, water, and energy. Releases large amounts of ATP
• What is the structure of mitochondria?

  Smooth outer membrane. Folded inner membrane. Folds called cristae. Space inside cristae called the matrix which contains a gel-like substance
• How does Acetyl coenzyme A form?

  Pyruvate is converted into acetyl CoA, releasing Co2 and producing NADH for next step
• What is the Krebs cycle?

  Aerobic respiration and takes place in matrix of mitochondria. Acetyl CoA is broken down to produce CO2 and ATP, NADH, and FADHs
• What is electron transport chain?

  Requires energy and takes place in the inner membrane. NADH and FADHs provide energy to produce ATP. The H released combines with oxygen to create water
