The process by which the glucose (6C compound) is split into two molecules of pyruvic acid (3C compound) is called glycolysis or EMP pathway. It occurs in the cytoplasm. Reactions involved in glycolysis are as follows: (i) The glucose is phosphorylated with ATP to form glucose-6-phosphate. The reaction is catalysed by the enzyme hexokinase. Thus, glycolysis produces both ATP for cellular energy requirements and building blocks for synthesis of other cellular products.This process occurs in all organisms, and is responsible for converting glucose to pyruvate and generating ATP in the process.
