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?

Isotopes of the same element have differ in their

How do all types of diffusion/passive transport actually ‘work’ without using even the smallest amount of cellular energy?
