Photosynthesis

3. a biochemical process in which cells break down glucose and oxygen to make carbon dioxide, water, and ATP for energy.
4. an individual living thing
5. organic compound that supplies energy to the body, such as sugar and starch.
9. process in which cells use carbon dioxide, water, and light energy to make oxygen and glucose, an energy-storing sugar.
11. first stage of photosynthesis
14. flattened sac of membrane inside a chloroplast where the first stage of photosynthesis occurs.
15. organelle in the cells of plants and algae, that contains chlorophyll and is the site of photosynthesis.
17. splitting water by light
18. sugar
20. a protein molecule that is attached to, or associated with, the membrane of a cell or an organelle.

1. green pigment in a chloroplast that absorbs light
2. second stage of photosynthesis in which carbon atoms from carbon dioxide are combined, using the energy in ATP and NADPH, to make glucose.
6. exchange of oxygen and carbon dioxide between the body and the outside air
7. organism that makes its own food.
8. organelle in the cell of plants and algae that contains chlorophyll and is the site of photosynthesis.
10. short-term energy carrier,temporarily stores energy during photosynthesis.
12. large, complex carbohydrate found in foods such as grains and vegetables that the body uses for energy.
13. organelle in eukaryotic cells that uses energy stored in glucose to make ATP.
16. energy-carrying molecule that cells use to power their metabolic processes
19. a protein that acts as a biological catalyst
