The two molecules that carry energized electrons to the second stage of the cellular respiration process are; NADH and FADH2.
Cellular respiration is a chemical process which involves the use of oxygen and glucose to produce carbon dioxide, water and energy in the form of ATP. Cellular respiration involves many chemical reactions and can be grouped into three stages: glycolysis, the Krebs cycle, and electron transport. The energy-carrying compounds; NADH and FADH2 are the molecules that carry energized electrons to the second stage (the Krebs cycle) of the cellular respiration process.
The 2 molecules that carry energized electrons to the second stage of the cellular respiration process, would be D. NADH and FADH2. These are carrying corresponding electrons via or with hydrogen atoms attached to the molecules.
