  1. Oxygen is consumed.
  2. FADH2 is produced.
  3. ATP is synthesized.
  4. Carbon dioxide is consumed.
Grade 12 Taxonomy

  2. destroy old cell parts.
  3. make ribosomes.
  4. make proteins and lipids.
Grade 12 Macromolecules
How is fermentation related to the production of bread?
  1. The absence of oxygen converts the sugar in the bread dough into oxygen, which is then removed from the bread.
  2. The ATP produced through fermentation is used by the bakers to knead the dough into the proper shapes.
  3. Yeast cells undergo alcoholic fermentation, which creates carbon dioxide that makes bread rise.
  4. Bacterial cells in the dough convert sugars through lactic acid fermentation into oxygen, allowing the dough to increase in height.
Grade 12 Macromolecules
Catalase is an enzyme that speeds up which reaction?
  1. breakdown of hydrogen peroxide into oxygen and water
  2. breakdown of lipids in the gut
  3. synthesis of proteins from amino acids
  4. breakdown of lactose in the digestive system
