Glycolysis Overview

These flashcards cover key concepts related to glycolysis, including definitions of essential terms and the processes involved in glucose metabolism.

Glycolysis

The first step in the breakdown of glucose to extract energy for cellular metabolism.

Anaerobic

A process that does not require oxygen.

GLUT Proteins

Integral proteins that facilitate the diffusion of glucose into cells.

Pyruvate

A three-carbon sugar molecule produced at the end of glycolysis.

ATP (Adenosine Triphosphate)

The energy currency of the cell, produced during glycolysis.

NADH

The reduced form of NAD, a high-energy electron carrier produced in glycolysis.

Hexokinase

An enzyme that catalyzes the phosphorylation of glucose in the first step of glycolysis.

Phosphofructokinase

A rate-limiting enzyme that catalyzes the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate.

Substrate-Level Phosphorylation

The direct transfer of a high-energy phosphate group to ADP to form ATP without the involvement of an electron transport chain.

Isomerase

An enzyme that catalyzes the conversion of a molecule into one of its isomers.

Pyruvate Kinase

The enzyme that catalyzes the last step of glycolysis, producing pyruvate and ATP.
