2
exergonic reaction
In a(n) ________, the products contain less energy than the reactants, and the excess energy is released.
New cards
3
phosphoenolpyruvate
After 3PG rearranges to form 2- phosphoglycerate, ________ (PEP) is formed, which donates a phosphate group to molecules of ADP to form another pair of ATP molecules and pyruvate.

4
Catalysts
________ speed up reactions by lowering the energy (activation energy) needed for the reaction to take place, but are not used up in the reaction.
New cards
5
Noncompetitive inhibition an inhibitor molecule
________ binds to a different part of the enzyme, causing a change in the shape of the active site so that it can no longer interact with the substrate.
New cards
6
