Electrons are removed from Nadh and Fadh2

Explanation:

The electron transport chain (ETC) is the last step of cellular respiration, which occurs in the mitochondria.

During ETC:

Protons are moved across a membrane against their concentration gradient.

Electrons are removed from the carrier molecules NADH and FADH2.

The ETC is a series of redox reactions that involve the transference of electrons from donors to acceptors, which is coupled to the transference of protons across the inner membrane of mitochondria.

The objective of the ETC is to synthesize ATP (the energy coin of the cell) by using the electrochemical proton gradient across the inner mitochondrial membrane.

NADH and FADH2 are the reduced forms of Nicotinamide adenine dinucleotide and Flavin adenine dinucleotide, respectively.

In conclusion, during the electron transport chain, 1-protons are moved across a membrane against their concentration gradient, and 2-electrons are removed from the carrier molecules NADH and FADH2.

The first option, the second option and the last option is what applies during the electron transport chain

Electrons are removed from their carrier molecules as the molecules will lose energy bit by bit

Protons are moved across a membrane

Oxygen is not a waste product since it is very useful, water is the waste product

Carbon Dioxide is released as it is another waste product

when it is at an intermediate population density
