Detailed explanation-1: -These electron transfers occur in the internal part of the cell membrane of prokaryotes cells. ETS takes place in a plasma membrane which is a lipid bilayer that encloses a prokaryotic cell cytoplasm.

Detailed explanation-2: -In prokaryotes, the electron transport chain components are found in the plasma membrane.

Detailed explanation-3: -It occurs in mitochondria in both cellular respiration and photosynthesis. In the former, the electrons come from breaking down organic molecules, and energy is released. In the latter, the electrons enter the chain after being excited by light, and the energy released is used to build carbohydrates.

Detailed explanation-4: -The electron transport chain activity takes place in the inner membrane and the space between the inner and outer membrane, called the intermembrane space.

Detailed explanation-5: -Electron Transport Chain is a series of compounds where it makes use of electrons from electron carrier to develop a chemical gradient. It could be used to power oxidative phosphorylation. The molecules present in the chain comprises enzymes that are protein complex or proteins, peptides and much more.
