| Question | Answer |
|---|---|
| The measurement of randomness in a system. | entrophy |
| Each time energy is converted from one level to another, some energy is last as what? | heat |
| Is the energy molecule of the cell. | ATP |
| ATP stores its energy in chemical bonds between which groups? | phosphates |
| In this reaction the products have more energy. | endergonic |
| In this reaction the reactants have more energy. | exergonic |
| Which pump in your cells is driven by the energy molecule? | sodium-potassium pump |
| In the body, special proteins lower what of a chemical reaction? | activation energy |
| Proteins that lower the activation energy of a chemical reaction are called what? | enzymes |
| What are the molecules that proteins work on? | substrate |
| Enzymes temporarily shut down when the end product binds to what site? | active site |
| The process by which most processes in the body are carried out. | metabolic |
| Chymotripsin breaks a peptide bond on this site. | amino acid chain |
| Energy in motion is..? | kinetic |
| Reaction that releases energy and tends to occur by itself. | Exergonic |
| Reaction that requires energy from an outside source and can repair damaged tissue. | Endergonic |
| Reaction in which the product must be synthesized. | Endergonic |
| The digestion of food is an example of this reaction. | exergonic |
| In this reaction the products have more energy than the reactants. | endergonic |
| In this reaction the products have less energy than the reactants. | exergonic |
| No mass and does not occupy space. | Energy |
| Stored energy is..? | potential energy |
| potential energy examples | gamma rays, UV rays, x-rays |
| Highly disorganized, low energy | high entrophy |
| Highly organized, high energy | low entrophy |
| Requires energy (walking) | endergonic |
| Produces or generates energy (eating) | exergonic |
| The creating and releasing of energy is what type of reaction? | coupled reaction |
| Biological catalyst that speeds up an exergonic reaction. | enzymes |
| Accepts electrons from oxidation reactions, Niacin, reduces NADH + H+. | NAD+ |
| Accepts hydrogen atoms, reduces to FADH2, riboflavin. | FAD |
| Carry an acetyl group in degradation of food stuff, vitamin B3. | CoA |
| Specific enzyme for a particular reaction. | specifity |
| Site on enzyme for signal molecule to bind. | Allosteric site |
| Site where reactant binds to enzyme. | binding site |
