9. organelle found in plants and photosynthetic protists that converts sunlight to chemical energy
11. substance that increases the hydrogen ion concentration of a solution
12. a metabolic pathway that consumes energy to synthesize molecules
14. the variable whose value is measured to see if it is influenced by another factor
18. monomer of carbohydrates
19. steroid that forms an essential component of animal cell membranes
23. a macromolecule serving as a catalyst without being consumed in the reaction
24. storage polysaccharide in anmials
25. membrane-enclosed sac of hydrolytic enzymes found in animal cells
27. organelle where cellular respiration takes place

1. a substance that reduces the hydrogen ion concentration in a solution
2. structural polysaccharide of plant cells
3. a metabolic pathway that releases energy by breaking down molecules
4. non-membrane-enclosed area in a prokaryote where its chromosomes are located
5. storage polysaccharide in plants
6. monomer of proteins/polypeptides
7. the reactant on which an enzyme works
10. process in which a protein loses its native shape
13. a type of strong bond where two atoms share one or more pairs of electrons
15. these are synthesized by the rough ER
16. having no affinity for water
17. the linking of like molecules, often by hydrogen bonds
20. these are synthesized by the smooth ER
21. chemical reaction that breaks bonds between 2 molecules by adding water
22. the variable that is manipulated or changed to reveal effects on another factor
26. complex of rRNA and protein molecules where protein synthesis takes place
28. the clinging of one substance to another by hydrogen bonds
