Question

In eukaryotes, most of the high-energy electrons released from glucose by cellular respiration __________. a. are bound to FAD to be sent through the process of oxidative phosphorylationb. are used for synthesizing lactic acidc. are used to form ATP by the citric acid cycled. reduce NAD+ to NADH, which then delivers them to the electron transport chain

Answer 1

The correct answer is "reduce NAD+ to NADH, which then delivers them to the electron transport chain".

Step-by-step explanation:

During cellular respiration, high-energy electrons are released from glucose and they move gradually through the electron transport chain towards oxygen. Most of these high-energy electrons are used to reduce NAD+ to NADH, which then delivers them to the electron transport chain. The reduction of NAD+ is the first step of the electron transport chain, which is transported from NADH and FADH2 to molecular oxygen.
