B. NADH
C. FADH2
D. NADPH
*Not sure which one it is.

There are a few energy carrier produced during Glycolysis but NADH and ATP are most produced.
The energy in light raises some of the electrons in chlorophyll to higher energy levels. These high-energy electrons are used in photosynthesis. Electron carriers are used to transport the electrons from chlorophyll to other molecules during photosynthesis.
You won't like the answer....but electrons are charge carriers and neither their speed nor their energy has much to do with what happens within an electric circuit.
The immeadiate source of energy used by the mitochondria is ATP (Adenosine Triphosphate) which is cellular energy. First Glycolysis (the breaking down of glucose) becomes pyruvic acid after it's broken down. Then in the Krebs Cycle, the pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions. This later generates a high amount of NADH and FADH2 which are electron carriers. These electron carriers are then sent to the Electron Transport chain where it is used to convert ADP into ATP which the mitochondria then uses.

NADH and ATP
to accept high energy electrons
There are a few energy carrier produced during Glycolysis but NADH and ATP are most produced.
ATP provides energy to break down glucose during glycolysis.
The cells do with all those high-energy electrons in carriers like NADH? in the presence of oxygen, those electrons can be used to generated huge amounts of ATP.
produced and consumed
The energy in light raises some of the electrons in chlorophyll to higher energy levels. These high-energy electrons are used in photosynthesis. Electron carriers are used to transport the electrons from chlorophyll to other molecules during photosynthesis.
The electron transport chain is a series of special molecules in the mitochondrion that receives the high-energy electrons from the carriers.
NADH
they provide energy carriers
NADH and FADH are Coenzymes which act as carriers of electrons, protons, and energy in metabolism.
