The Working Cell

2. type of reaction where the end products have more energy than than the reactants did
3. type of diffusion where membrane proteins assist the movement of the molecule across the membrane
6. type of solution where the amount of dissolved solute is the same on the inside of the cell, as outside the cell
7. type of transport across plasma membrane that requires no energy
8. type of transport across plasma membrane that requires proteins and ATP
9. rate of a reaction is proportional to enzyme ______________
11. is selectively permeable and regulates transport of molecules in and out of cell
12. type of transport the moves liquids or small particles into a cell
15. sum of all chemical reactions in a cell
16. type of transport that moves macromolecules out of the cell
17. capacity or ability to do work
18. measure of disorder or randomness

1. used to control metabolic pathways, where product competes for the active site of an enzyme earlier in the pathway
4. energy of ____________ is the amount of energy that reactants must absorb in order to start a chemical reaction
5. type of diffusion where molecules move down their concentration gradient until equilibrium is achieved and they are distributed equally. no energy or membrane required
7. likely the first organic molecule to form on Earth
10. a non-protein component that many enzymes require to to be efficient
13. too high or too low __________________ may denature or inactivate an enzyme
14. reactant in an enzymatic reaction
16. globular proteins that are organic catalysts, efficient at their job, and not degraded upon job completion
