Glycolysis

• Where does glycolysis occur?


  In the cytoplasm.
• What does glycolysis do?

  Converts one molecule of glucose into two pyruvate molecules.
• How many carbons does a pyruvate molecule have?

  3
• Why is glycolysis an anaerobic process?

  It doesn't require oxygen to take place.
• What does glycolysis also produce as well as pyruvate?

  2 ATP molecules and 2 reduced NAD molecules.
• What is also needed in glycolysis?

  2 ATP molecules.
• What happens during phosphorylation of glycolysis?

  2 ATP molecules donate phosphate groups to glucose, splitting the glucose into 2 molecules of triose phosphate (TP).
• What happens during oxidation in glycolysis?

  A hydrogen atom is removed from each TP molecule , converting them into pyruvate molecules.
• What happens to the hydrogen atoms released in glycolysis?

  They are used to reduce NAD.
• What happens after glycolysis if oxygen is available?

  Pyruvate moves through the mitochondrial membrane by active transport to be used in the link reaction.
• How are the 4 ATP molecules produced during oxidation of TP?

  By substrate-linked phosphorylation.
