Grade 12 Macromolecules
An ATP molecule is made up of
  1. matrix, inner membrane, and outer membrane.
  2. NADH, NADPH, and FADH.
  3. adenine, phosphate groups, and ribose.
  4. proteins, carbohydrates, and nucleic acids.
Grade 12 Macromolecules
Are enzymes reusable?
  1. yes
  2. no
  3. sometimes
Grade 12 Macromolecules
What property makes phospholipids the ideal organic molecule to make up the cell membrane?
  1. Phospholipids dissolve easily in water, so materials can pass through them without the need for energy.
  2. Phospholipids contain many mitochondria, so the cell membrane has all the energy it needs to undergo mitosis.
  3. Phospholipids maintain their shape all the time, so organisms made from these cells can grow very large.
  4. Phospholipids have hydrophobic and hydrophilic ends, so cells can live in an aqueous environment and still carry out all their functions.
