review chapter 2-4

5. transport that moves against concentration gradient
7. this is a dual pump and is an example of primary active transport
11. control center of the cell
12. has two components the cytosol and organelles
15. play a role recognizing of infected cells
16. the study of energy transformation
18. when a phosphate group is added
20. molecules move down concentration gradient does not use energy neither a protein carrier
21. the only macromolecule that does not have monomer

1. is also known as "Cell drinking"
2. type of bond found in DNA that forms its "backbone"
3. control what substance can cross freely.
4. powerhouse of the cell
6. reaction with an input of energy
8. the only step in cellular respiration that does NOT required oxygen.
9. this process makes ATP
10. is also known as "cell eating"
12. the smallest structural and functional unit of life
13. the universal solvent
14. is a type of the protein that is expose outside of the vesicle that mean is contaminated.
17. compund that lack carbon
18. has amino acid as its monomer
19. a solution becomes acidic when more of these ions are added
