Glycolytic Pathway

Overview

The glycolytic pathway, also known as glycolysis, is a metabolic pathway that converts glucose into energy in the form of ATP.

Glucose

Glucose is a 6-carbon sugar molecule (C6H12O6) that serves as the primary source of energy for cells.
It is a universal energy currency for cells, providing energy for various cellular processes.

Glucose Phosphorylation

The first step of glycolysis involves the phosphorylation of glucose to form glucose-6-phosphate (G6P).
This reaction is catalyzed by the enzyme hexokinase and requires one ATP molecule.
Glucose phosphorylation traps glucose within the cell and begins the process of energy extraction.

Glycolysis

Glycolysis is a 10-step metabolic pathway that converts glucose-6-phosphate into pyruvate.
The pathway involves a series of enzyme-catalyzed reactions, resulting in the production of:
- 2 ATP molecules (net gain)
- 2 NADH molecules
- 2 pyruvate molecules

ATP Synthesis

The energy generated from glycolysis is used to synthesize ATP through the process of substrate-level phosphorylation.
During glycolysis, 2 ATP molecules are invested, and 4 ATP molecules are generated, resulting in a net gain of 2 ATP molecules.
The ATP molecules produced in glycolysis are used to fuel various cellular processes.
