AP Biology Unit 3 Glycolysis

Front

What is glycolysis?

Back

Glycolysis is a metabolic pathway that converts glucose into pyruvate, producing energy in the form of ATP and NADH.

Front

What is the main function of glycolysis?

Back

To split the glucose molecule to release energy.

Front

What is the starting material for glycolysis?

Back

Glucose.

Front

How many steps are there in glycolysis?

Back

There are 10 steps in glycolysis.

Front

How many enzymes catalyze the steps of glycolysis?

Back

10 enzymes catalyze the steps of glycolysis.

Front

Does glycolysis require oxygen?

Back

No, glycolysis does not require oxygen (it is anaerobic).

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytosol of the cell.

Front

What are the end products of glycolysis?

Back

The end products of glycolysis are 2 pyruvate molecules, 2 ATP, and 2 NADH.

Front

What is the role of NAD+ in glycolysis?

Back

NAD+ acts as an electron carrier, accepting electrons during the oxidation of glucose.

Front

What happens to pyruvate after glycolysis in the presence of oxygen?

Back

In the presence of oxygen, pyruvate is converted into acetyl CoA and enters the Krebs cycle.
