Medial is the answer as far as i know
Electrons are brought to the electron transport system by the oxidation of NADH and FADH2.
The electron transport chain is a group of proteins located within the inner membrane of the mitochondria which transport electrons. Electrons are passed from one member of the transport chain to another in a series of redox reactions, forming a proton gradient which is then used for ATP production.
NADH and FADH2 are reduced electron carriers which are oxidized into NAD+ and FAD near the beginning of the electron transport chain.
Isn’t it 37.2 trillion cells if that is wrong sorry
The carbon cycle is basically the bigeochemical cycle in which carbon is exchanged between the four main cycles.<span>They are the biosphere, hydrosphere, atmosphere and geosphere. This is a small summary of what it is. Hoped this helps :D</span>
Experiment are special test that are conducted under certain circumstance and can be replicable.
if we cannot replicate it then it is just a test.
experiment should be replicable so it can be done by other people too
