Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In bacterial cells, the electron transport system is located in the
A
cell membrane
B
mitochondria
C
chloroplasts
D
ribosomes
Explanation: 

Detailed explanation-1: -The electron transport chain and eukaryotes is found either in the mitochondria or the thylakoid membrane of chloroplast. In bacteria the electron transport chain is found in the plasma membrane of the organism.

Detailed explanation-2: -The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

Detailed explanation-3: -In eukaryotes, the electron transport chain is located in the inner mitochondrial membrane. In prokaryotes, it is located within the plasma membrane. Electrons move through the electron transport chain from a higher to lower energy state.
