NADH and FADH2 are necessities in the electron transport chain because they power the chain by moving electrons into it.
NADH and FADH2 are both generated at the initial stages of respiration (the Kreb's cycle), a process during which food materials are broken down to generate energy. NADH is generated from NAD+ as a result of the addition of electrons while FADH2 is generated from FAD also due to the addition of electrons.
Once generated, both compounds get transferred into the innermost membrane of the mitochondrion where they travel down the electron transport chain, donating their electrons in the process and creating an electrochemical gradient to generate ATP.
Without NADH and FADH2, there will not be electrons to power the electron transport chain and the generation of ATP would become impossible.

Peat moss allows a soil a greater ability to not just hold water, but to hold it in a way that it's available to plant roots. If a soil is too clay, it will hold water but not give it up. If a soil is too sandy, water drains away too quickly.
They are examples of Acids
hi there
your answer to this response is
Energy, water, and carbon dioxide are produced. Finally, when is the glucose molecule is broken down, the waste products are six molecules of carbon dioxide. (6CO2) and six molecules of water (6H2O). Photosynthesis The waste product of cellular respiration, carbon dioxide, is just what green plants need for photosynthesis.
Ihope this helps you out i have great afternoon
