Study Notes

Glycolysis

  • Glycolysis takes place in the cytosol of the cell.
  • The main product of glycolysis is pyruvate.
  • Glycolysis involves the breakdown of one glucose molecule into two pyruvate molecules.
  • NADH plays a key role in glycolysis as an electron carrier.

Citric Acid Cycle (Krebs Cycle)

  • The Citric Acid Cycle (Krebs Cycle) takes place in the mitochondrial matrix.
  • The first step of the Krebs Cycle involves the conversion of acetyl-CoA into citrate.
  • FADH2 is an electron carrier in the Krebs Cycle, playing a crucial role in energy production.

Electron Transport Chain

  • The Electron Transport Chain involves Chemiosmosis, which generates ATP through the movement of protons across the mitochondrial membrane.
  • The enzyme responsible for ATP production in the Electron Transport Chain is ATP synthase.
  • NADH and FADH play a crucial role in the Electron Transport Chain as electron carriers, transferring electrons to generate ATP.

This quiz covers the basic features and importance of photosynthesis and respiration, differentiation between aerobic and anaerobic respiration, chemical events and sequences of cellular respiration, and major features of glycolysis, Krebs cycle, electron transport system, and chemiosmosis.
