Question

Write the reactant and product of glycolysis

Answer 1

Glycolysis involves the breakdown of glucose into two molecules of pyruvate, with a net gain of two ATP molecules and production of two NADH molecules. It starts with glucose and ends with pyruvate, ATP, and NADH.

Step-by-step explanation:

The reactant of glycolysis is glucose, and the main products are pyruvate, ATP, and NADH. Glycolysis can be summarized by the following chemical equation:

Glucose + 2ATP + 2NAD+ + 4ADP + 2P₁ → 2 Pyruvate + 4ATP + 2NADH + 2H+

Through this metabolic pathway, one molecule of glucose is broken down into two molecules of pyruvate. Additionally, two molecules of ATP are used in the early stage of glycolysis, but four molecules of ATP are produced, resulting in a net gain of two ATP molecules. Two molecules of NADH, which are used to transport electrons for further ATP generation in the mitochondria, are also produced in glycolysis.

Answer 2

Reactants: glucose and 2 ATP molecules

Products: pyruvate, ATP and NADH
