Question

Several different molecules carry high-energy electrons to the electron transport chain to generate ATP molecules.
Which of these high-energy electron carriers is only generated in the Krebs cycle?

• A. NADPH
• B. FADH${}_2$
• C. NADH
• D. ATP

Answer 1

The correct option is B FADH${}_2$

The high energy electron carriers that are generated only during Kreb's cylce is FADH${}_2$, it also includes NADH and ATP, which are also generated during photosynthesis

So, the correct answer is 'FADH${}_2$'
