unit 3 test

1. the bindig of a regulatory molecules to a protein at one site that affects the function of the protein at a different site
4. organic molecules serving as a cofactor
5. an energy-coupling mechanism that uses energy stored in the form of a hydrogen ion gradient across a membrane to drive cellular work
6. a catabolic process that makes a limited amounf of ATP
8. a metabolic pathway that consumes energy to synthesuze a complex molecule from simpler molecules
12. a metabolic pathway that releases energy by breaking down complex molecules to simpler molecules
14. a series of reactions that splits glucose into pyruvate

2. a nonspontaneous chemical reaction in which free energy is absorbed from the surroundings
3. a spontaneous chemical reaction in which there is a net release of free energy
7. the entry compund for the citric acid cycle in cellular respiration, formed from a two-carbon fragment of pyruvate attached to a coenzyme
9. a process by which a chemical agent called a catalyst selectively increases the rate of reaction without being consumed by the reaction
10. reduced form of nicotinamide adenine dinucleotide that stores electrons
11. an adenine-containing nucleotide triphosphate that releases free energy when its phosphate bonds are hydrolyzed.
13. a catabolic pathway for organic molecules using oxygen as the final electron acceptor & producing ATP
