Glycolysis & Pyruvate Oxidation

Where does glycolysis take place in cells?

• Cytosol

• Mitochondrion

• Endoplasmic Reticulum

• Ribosomes

The first step of glycolysis formation is

• ATP

• Fructose-6-Phosphate

• Glucose-6-Phosphate

• 1,6 Bis-PhosphoGlycerate

Glycolysis gain net products of:

• 4 ATP

• 4 NADH

• 2 Acetyl CoA

• 2 ATP

In the final step of glycolysis ATP is made through the process of

• Redox Reactions

• Substrate-level Phosphorylation

• Photo-Phosphorylation

• Oxidative Phosphorylation

What is the function of NAD+ ?

• It accepts oxygen during ETC

• It is the oxidized form of an energy carrier

• It is the reduced form of an energy carrier

• It acts as long-term energy storage

Which statement best describes the reaction?

• Pyruvate reacts with CoA, oxidizing NADH

• Pyruvate is decarboxylated; acetyl coA is formed, oxidizing NADH

• Pyruvate is decarboxylated; acetyl COA is formed, reducing NAD+

• Pyruvate is carboxylated; acetyl COA is formed, reducing NAD+

Which of the following does not happen during Pyruvate Oxidation?

• Oxygen is oxidized

• NAD+ is reduced

• A CO2 portion is removed per molecule of pyruvate

• Coenzyme A is attached to the remaining ascetic acid portion (acetyl group)

Which of the following is the correct overall equation of pyruvate oxidation?

• 2 pyruvate + 2 NAD+ + 4 COA ---> 2 acetyl-CoA + 2 NADH + 2H+ + 4 CO2

• 2 pyruvate + 2 NAD+ + 4 COA ---> 4 acetyl-CoA + 2 NADH + 2H+ + 2 CO2

• 2 pyruvate + 2 NAD+ + 2 CoA ---> 2 acetyl-CoA + 2 NADH + 2H+ + 2 CO2
