Understanding Glycolysis

What is the primary role of glycolysis in cellular respiration?

• To produce oxygen

• To split glucose and begin energy production

• To create carbon dioxide

• To synthesize proteins

During the Preparatory phase of glycolysis, how many ATP molecules are used?

• Three

• Four

• Two

• One

What happens to the glucose molecule at the end of the Preparatory phase?

• It is converted into pyruvate

• It is split into two smaller sugar molecules

• It remains unchanged

• It is used to produce oxygen

How many ATP molecules are produced during the Payoff phase of glycolysis?

• Six

• Eight

• Four

• Two

What are the end products of glycolysis?

• Glucose and oxygen

• Pyruvate, ATP, and NADH

• Carbon dioxide and water

• Lactic acid and ATP
