  1. Question 1

    Q1. According to the PTB text, how many ATP molecules are theoretically produced from the oxidation of one NADH and one FADH2 respectively?

    • A) 3 ATP from NADH; 2 ATP from FADH2
    • B) 2.5 ATP from NADH; 1.5 ATP from FADH2
    • C) 2 ATP from NADH; 3 ATP from FADH2
    • D) 4 ATP from NADH; 2 ATP from FADH2

    Answer: 3 ATP from NADH; 2 ATP from FADH2

    Explanation: PTB states 1 NADH yields 3 ATP and 1 FADH2 yields 2 ATP. Option B reflects modern values not used in PTB.
