Unit 3 - Cellular Energetic

F6P

F6P

________- splits into two 3- carbon- long fragments known as PGAL (glyceraldehyde phosphate); with the formation of PGAL, the energy- producing portion of glycolysis begins.

exergonic reaction

In a(n) ________, the products contain less energy than the reactants, and the excess energy is released.

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.

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.

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.

Glycolysis

________- produces the same result under anaerobic conditions as it does under aerobic conditions- two ATP molecules.
