Mitochondria in Glycolysis Quiz

What is the primary role of mitochondria in the process of glycolysis?

• To produce glucose

• To generate ATP

• To store energy

• To break down pyruvate

Which of the following is the first step in the glycolysis pathway?

• Conversion of glucose to glucose-6-phosphate

• Conversion of pyruvate to acetyl-CoA

• Conversion of fructose-6-phosphate to fructose-1,6-bisphosphate

• Conversion of 3-phosphoglycerate to 2-phosphoglycerate

How many ATP molecules are produced during glycolysis?

• 2

• 4

• 6

• 8

What is the net gain of ATP molecules in glycolysis?

• 1

• 2

• 3

• 4

Which enzyme is responsible for the phosphorylation of glucose in the first step of glycolysis?

• Hexokinase

• Phosphofructokinase

• Aldolase

• Enolase

What is the end product of glycolysis?

• Acetyl-CoA
