  1. 3. This is the main pigment that absorbs sunlight in photosynthesis
  2. 7. The abbreviation for an energy-carrying molecule that, when split apart, provides a lot of energy for our cells to do work. Hint: this molecule is created during cellular respiration
  3. 9. A molecule that binds to an enzyme and increases its activity. Examples include vitamins and minerals.
  4. 12. Stored energy is ______energy. For example, the energy stored inside chemical bonds.
  5. 13. During the Calvin cycle or light-independent reactions in photosynthesis, this molecule is converted to glucose using the energy in ATP and NADPH (2 words)
  6. 14. Many anaerobic organisms that do not breathe oxygen undergo ______, a process that breaks down glucose to get some energy, but is not as efficient as cellular respiration.
  7. 16. Enzymes are able to speed up the rate of a chemical reaction because they lower the amount of energy needed to start the reaction, also known as the reaction’s _______ (2 words)
  8. 17. All plasma membranes are comprised of _____(plural), which form a bilayer (one layer on top, one on bottom).
  9. 18. The membrane protein that is used in cellular respiration and photosynthesis to synthesize ATP (2 words)
  10. 20. The abbreviation for the final pathway in cellular respiration that produces the most ATP
Down
  1. 1. Diffusion of water across a selectively permeable membrane is known as ______.
  2. 2. This process breaks down glucose in order to harvest energy from it. The cell uses this energy to do work (2 words).
  3. 4. The _____ binds to the active site on an enzyme (hint: it’s the name given to the reactants in an enzyme-catalyzed reaction)
  4. 5. ______diffusion is a type of diffusion that requires a membrane protein to transport a substance from one side of a plasma membrane to the other side. This type of transport requires no energy.
  5. 6. In an ______ reaction, energy is consumed (ball rolling uphill)
  6. 8. An _______solution is a type of solution where the concentration of solute and water is the same as that within a cell. Placing a cell in this type of solution will not affect the cell’s shape.
  7. 10. The opposite process of endocytosis, where material leaves the cell.
  8. 11. This process takes energy from the sun and makes chemical energy in the form of glucose (hint: only happens in plants)
  9. 15. The light reactions in photosynthesis take place in the thylakoid membranes of a chloroplast, while the light-independent reactions take place in the ______, or fluid, of the chloroplast.
  10. 19. Simple diffusion is a type of _____transport that requires no energy.
