4. the process by which carbohydrates are broken down in many steps to maximize energy release
6. the regulating enzyme at the beginning of the citric acid cycle
7. two of these three-carbon molecules are produced by the end of glycolysis
8. when a substrate binds to an enzyme somewhere other than the active site, changing the enzyme's conformation to either deactivate or further enhance activation of the enzyme
10. an enzyme works by stabilizing the ____________ state of a reaction
11. to catalyze a reaction, an enzyme lowers __________ ____________ of a reaction
14. These proteins have optimal temperatures and pHs to perform their function
15. the oxidized form of electron carrier FADH2

1. when a substrate binds to an enzyme's active site, preventing binding for the substrate that is supposed to attach
2. reactions are _________ when an exergonic reaction gives off the energy that a nearby endergonic reaction can use to lower its G
3. the process by which carbohydrate chains are added on to proteins to mark them, either in the rough ER or the golgi
5. this protein recognizes a signal sequence on a newly synthesizing protein and directs the ribosome making it to the rough ER
9. this part of the mitochindria is where the processes of pyruvate processing and the krebs cycle take place
12. the krebs cycle undergoes one "turn" per each molecule of ________ that enters it
13. the reduced form of electron carrier NAD+
