Amino acids are the molecules needed to form protein molecules. Proteins are made up of long chains of amino acids.
Amino acids!
There are exactly twenty amino acids that are the molecules that make up (comprise) the biologically active proteins found in and around The Cell.
Smaller molecules called amino acids make protein molecules.

Yes, an aquaporin is a type of channel protein that allows the passage of water molecules across cell membranes.
Active transport is the type of molecular movement when molecules move against the concentration gradient from low to high through protein pumps. This process requires energy input, typically in the form of ATP, to pump molecules across the cell membrane.
Two cysteine residues can form a covalent bond called a disulfide bond by oxidation of their thiol groups. This bond contributes to protein structure and stability, forming bridges between different regions of a protein or between different protein molecules.
