Justify that glycolysis evolved prior to the mitochondria

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

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

• Glycolysis has instructions in the nuclear DNA

• Glycolysis takes place in the cytosol

What is the main function of glycolysis?

• To rearrange the glucose molecule to be broken down

• To recreated acetyl CoA for the Krebs cycle

• To absorb and store energy in the ATP molecules

• To split the glucose molecule to release energy

How does glycolysis lead to ATP synthesis?

• Glucose provides the phosphate to ADP to synthesize ATP

• Acetyl CoA is synthesized for the Krebs cycle

• Glycolysis splits the glucose molecule to create G3P

• High energy electrons are stored in NADH for the ETC

What is the starting material for glycolysis?

• Pyruvate

• Glucose

• Acetyl CoA

• G3P

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

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

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

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

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