which of the following is true regarding the electron transport chain? (select all that is/are true) group of answer choices it occurs in the cytoplasm of a cell. it occurs in the mitochondria of a cell protons are actively pumped from the inner membrane space to the matrix via the ets complexes. molecular oxygen (o2) is required for it to operate nadh donates a hydride to complex i, which donates electrons to complex iii then to complex iv with o2 being the final electron acceptor.



Answer :

Option B. it occurs in the mitochondria of a cell protons are actively pumped from the inner membrane space to the matrix via the complexes  is true regarding the electron transport chain.

An electron transport chain is a sequence of protein complexes and different molecules that switch electrons from electron donors to electron acceptors via redox reactions and couples this electron switch with the switch of protons throughout a membrane. An electron transport chain (and so on) is a sequence of protein complexes ; The go with the flow of electrons thru the electron delivery chain is an exergonic manner.

The method of forming ATP from the electron delivery chain is referred to as oxidative phosphorylation. Electrons carried by using NADH + H+ and FADH2 are transferred to oxygen thru a series of electron companies, and ATPs are shaped. three ATPs are shaped from each NADH + H+, and two ATPs are formed for each FADH2 in eukaryotes.
