Channels and pumps are transmembrane proteins that create hydrophilic tunnels across the membrane. This allows molecules to be diffused through them. The channels and pumps are highly selective and only allow the diffusion of specific molecules. The channel's structure blocks the contact of the molecule with the head and tail of the phospholipids that form the membrane. As we said, the channels and pumps are proteins, so they are formed by amino acids. Therefore, the molecules passing through channels and pumps, only come in contact with the amino acids.
The peer review is the process of the review by the other members involved in the study of the same topic. The peer review increases the validation of the paper and is ready to be published after wards. Hence, after the peer review is completed and the claim present in the paper stand to be true, then the paper is ready to publish and the nest step must be the publishing of paper.
Phospholipids is the fundamental building block of a new cell membrane
