Cellular Respiration

AP Biology· difficulty 2/5

During cellular respiration, glucose is oxidized to CO₂. The electrons from glucose's C-H bonds are

  • A

    Transferred to NAD⁺ and FAD, then ultimately to O₂

  • B

    Transferred to NADPH and FADH, then ultimately to H₂O

  • C

    Transferred to ATP and ADP, then ultimately to CO₂

  • D

    Transferred to coenzyme A and pyruvate, then to lactate

Explanation

NAD⁺ and FAD are reduced to NADH and FADH₂, carrying electrons to the ETC where O₂ is the terminal acceptor.
