Glycolysis

How many glucose molecules start glycolysis?

1 glucose molecule.

Easy way to remember: 1 glucose goes in.

How many ATP are used at the beginning of glycolysis?

2 ATP.

Easy way to remember: pay 2 ATP to start.

How many ADP are produced when those ATP are used?

2 ADP.

Easy way to remember: 2 ATP used → 2 ADP.

How many NAD molecules are involved in glycolysis?

2 NAD.

Easy way to remember: 2 NAD enter → 2 NADH leave.

How many NADH + H⁺ are produced in glycolysis?

2 NADH + H⁺.

Easy way to remember: 2 NAD → 2 NADH.

How many ADP are used to make ATP later in glycolysis?

4 ADP.

Easy way to remember: 4 ADP are turned into 4 ATP.

How many total ATP are produced during glycolysis?

4 ATP total.

Easy way to remember: make 4.

If glycolysis makes 4 ATP but uses 2 ATP, what is the net ATP gain?

2 ATP net.

Easy way to remember: 4 made − 2 spent = 2 kept.

How many pyruvate molecules are produced from 1 glucose?

2 pyruvate.

Easy way to remember: 1 glucose → 2 pyruvate.

How many CO₂ molecules are produced during glycolysis?

0 CO₂.

Easy way to remember: glycolysis = zero CO₂.

How many FADH₂ molecules are produced during glycolysis?

0 FADH₂.

Easy way to remember: glycolysis = zero FADH₂.

What is the number sequence for glycolysis from beginning to end?

1 glucose → 2 ATP used → 2 NADH → 4 ATP made → 2 ATP net → 2 pyruvate.

Easy way to remember: “1 → 2 → 2 → 4 → 2 → 2.”
