Where does Glycolysis occur?

• mitochondria

• cytoplasm/cytosol

• nucleus

• membrane

Which is true regarding Pyruvate during cellular respiration?

• Pyruvate is oxidized into Acetyl Coenzyme A and releases CO₂ as a byproduct

• Pyruvate is reduced into NADH

• Pyruvate is oxidized into Acetyl CoA and releases Oxygen as a byproduct

• Pyruvate is oxidized into Acetyl Coenzyme A and FAD+ is reduced into NADH

Which is correct regarding the Cellular respiration stage of Glycolysis?

• It is when Pyruvate is degraded and combined with coenzyme A, forming acetyl CoA and releasing CO₂

• It is a series of reactions in which the acetyl CoA is degraded to CO₂ and ATP is synthesized

• It is a series of reactions where Glucose is degraded to pyruvate and produces 2 net ATPs (It can proceed anaerobically)
