Q. 18.21 - An Introduction to General, Organic, and Biological Chemistry

Question

How is $ATP$ used in initial steps of glycolysis.

Step-by-Step Solution

Answer

$ATP$ molecules used to prepare the six carbon ring for cleavage. 

Step 1: Given Information

We need to find how $ATP$ molecules used in glycolysis.

Step 2: Explanation

We know that Glycolysis starts with glucose and ends with two pyruvate molecules, a total of four $ATP$molecules and two molecules of $NADH$. Two  molecules were used in the first half of the Pathway to prepare the six carbon ring for cleavage, so the cell has a net gain of two $ATP$ molecules and two $NADH$molecules for its use.
