Many of the redox center that comprise the electron transport system (ETS) are integral components of larger protein complexes. whereas others, such as , freely diffuse within the membrane as they ferry electrons between other ETS components.

Monomers are the building blocks of larger molecules, called polymers. for example, proteins are composed of chains of amino acids that are linked together. cellulose is a polymer that makes up plant cell walls. cellulose is made from a chain of c6h10o5 molecules. which monomers are most likely used to produce cellulose? why?
