The Enzyme Pyruvate Kinase Catalyzes the Conversion of Phosphoenolpyruvate to Pyruvate;

question 1

Multiple Choice

The enzyme pyruvate kinase catalyzes the conversion of phosphoenolpyruvate to pyruvate; the phosphate group is transferred to ADP to form ATP. This reaction is an example of

• A) ATP synthesis by substrate-level phosphorylation.
• B) the use of a proton concentration gradient by [H+]-ATPases to synthesize ATP.
• C) ATP coupled to FADH2 oxidation.
• D) a P-Type ATPase activity.
• E) oxidative phosphorylation.
