What is the main function of glycolysis?

• To rearrange the glucose molecule to be broken down

• To split the glucose molecule to release energy

There are 10 steps in glycolysis, how many enzymes catalyze these steps?

• 8

• 9

• 10

• 11

What are the products of glycolysis?

• 2 ATP, 2 NADPH, 2 pyruvate

• 2 ADP, 2 NADH, 2 pyruvate

• 2 ATP, 2 NADH, 2 pyruvate

• 2 ADP, 2 NADPH, 2 pyruvate

How does glycolysis lead to ATP synthesis?

• Glucose provides the phosphate for ADP to synthesize ATP

• Glycolysis splits the glucose molecule to create G3P

• High energy electrons are stored in NADH for the ETC

• Acetyl CoA is synthesized for the Krebs cycle

Justify that glycolysis evolved before oxygen was present in the atmosphere.

• Glycolysis does not require oxygen which represents that it evolved prior to free oxygen in the atmosphere.

• Glycolysis does not take place in the mitochondria and thus does not require oxygen.

• Glycolysis splits a glucose molecule into 2 pyruvate molecules which does not require oxygen.

• Glycolysis takes place in all living organisms which means it evolved prior to free oxygen in the atmosphere.

Justify that glycolysis evolved prior to the mitochondria.

• Glycolysis takes place in the cytosol.

• Glycolysis does not require a membrane which represents that it evolved prior to membrane bound organelles.

• Glycolysis has instructions in the nuclear DNA.

• Glycolysis does not require mitochondrial DNA which represents that it evolved prior to membrane bound organelles.
