Verified step by step guidance1
Understand the process of glycolysis: Glycolysis is the metabolic pathway that converts glucose into pyruvate, releasing energy and reducing NAD+ to NADH in the process.
Identify the main reactants in glycolysis: The primary reactant is glucose, which is broken down during the process. Additionally, ATP is used in the initial steps to phosphorylate glucose.
Identify the main products of glycolysis: The end products of glycolysis are pyruvate, ATP, and NADH. Pyruvate is the final product of the glucose breakdown, while ATP and NADH are generated as energy carriers.
Evaluate the given options: Compare each option to the identified reactants and products. The correct option should list glucose and ATP as reactants, and pyruvate, ATP, and NADH as products.
Select the correct answer: Based on the evaluation, choose the option that correctly lists glucose and ATP as reactants, and pyruvate, ATP, and NADH as products.
