glycolysis a level

What is the net gain of ATP molecules in glycolysis?

• 4

• 2

• 0

• 6

What is the evolutionary significance of glycolysis?

• Glycolysis is a process that converts glucose into oxygen.

• Glycolysis is a process that converts glucose into carbon dioxide.

• Glycolysis is a process that converts glucose into water.

• Glycolysis allowed early organisms to generate energy from glucose in the absence of oxygen.

What is the role of NAD+ in glycolysis?

• It is reduced to NADH, which is used in the electron transport chain

• It is oxidized to NADH, which is used in the Krebs cycle

• It is reduced to NADH, which is used in the conversion of pyruvate to lactate

• It is oxidized to NADH, which is used in the conversion of glucose to glucose-6-phosphate

What is the significance of the investment phase in glycolysis?

• It generates ATP and NADH

• It consumes ATP to activate glucose for subsequent reactions

• It produces pyruvate as the end product

• It involves the conversion of glucose to fructose-6-phosphate

How many ATP molecules are invested to start glycolysis?

• 2

• 4

• 6

• 1

Finish the phrase: “As the bonds in glucose are _______ and rearranged, energy is __________.”

• broken, released

• built, trapped

• broken, trapped

• built, released

Which of the following is the correct chemical equation for Cellular Respiration?

• C₆H₁₂O₆ + 6O₂ --> 6CO₂ + 6 H₂O + ATP Energy

• C₆H₁₂O₆ + H₂O --> 6CO₂ + 6 6O₂ + ATP Energy
