25 Questions

1. The putting together of living things

2. Organic compounds that contain carbon - hydrogen and oxygen; provide structure and store energy

3. Gives off heat; exo - outside

4. Homogenous(alike) mixture of one or more substances in another substance

5. When a cell needs a monosaccharide - enzymes cause disaccharides to undergo hydrolysis - which means the breaking down of a disaccharide by adding a water molecule

6. Matter is composed of ______

7. Proteins only one that are...

8. Group of organic substances slightly soluble in water; very soluble in other organic liquids; mostly structural but also store energy; humans and animals store their excess energy as lipids

9. Most abundant form of lipids; building blocks for other lipids; have hydrophilic and hydrophobic ends; in water - will align themselves; good source of energy; found in dairy and animal tissues

10. Single sugars; glucose(C6H12O6) is a monosaccharide that is manufactured by plants in photosynthesis

11. The ability to do work

12. Composed of long chains of glucose; is a polysaccharide; found in plant cell walls; nondigestible by most animals; part of our diet called bulk or rubbage(fiber)

13. Polysaccharide; strong and flexible; makes up shells of crabs - lobsters - shrimp - insects; found in cell walls of fungi

14. Mixture of fine particles that do not settle out quickly (ex. protoplasm)

15. Cannot change between gel and sol (ex. egg whites)

16. Another nucleic acid; single strand; sometime replaces thymine

17. Many sugars; complex carbs

18. Dissolver (water: universal solvent)

19. Process of making two DNA molecules from one strand

20. Stored energy

21. Polysaccharide; animal starch (animals and humans eat starches abd break them down to monosaccharides; the liver converts them to glycogen for storage)

22. What is chief ingredient in living things?

23. Absorbs heat; endo - within

24. Made of nucleotides; sugar - phosphate - base; adenine - thyOOmine; guani`ne - cytosine

25. The diffusion of water(!!) through a semipermiable membrane; equilibrium is never reached.
