  • What is the balanced chemical equation for cellular respiration?
    The balanced chemical equation for cellular respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.
  • Which chemical process generates the ATP produced in glycolysis?
    The ATP produced in glycolysis is generated through substrate-level phosphorylation.
  • How do cells oxidize their glucose?
    Cells oxidize glucose through glycolysis, converting it into pyruvate while producing ATP and NADH.
  • Which is the electron carrier that accepts electrons during glycolysis?
    NAD+ is the electron carrier that accepts electrons during glycolysis, becoming reduced to NADH.
  • What happens to the glucose molecule in the first step of glycolysis?
    In the first step of glycolysis, glucose is phosphorylated to form glucose-6-phosphate.
  • What happens to glucose during glycolysis in terms of its chemical transformation?
    B) Glucose is oxidized to pyruvate in glycolysis.
  • What is the purpose of NADH made during glycolysis?
    The purpose of NADH made during glycolysis is to carry electrons to the electron transport chain for ATP production.
  • Which molecule would you expect to act as an allosteric activator of an enzyme in glycolysis?
    AMP is a molecule that acts as an allosteric activator of enzymes in glycolysis, indicating low energy status in the cell.
  • What is the electron carrier in glycolysis that becomes reduced?
    NAD+ is the electron carrier in glycolysis that becomes reduced to NADH.
  • What molecule acts as an electron acceptor in glycolysis?
    NAD+ acts as an electron acceptor in glycolysis.
  • What does the oxidation of glucose release?
    The oxidation of glucose releases energy in the form of ATP and produces NADH and pyruvate.
