6. what adsorbs last to a biomaterial surface? a. stable/hard proteins with a low concentration b. unstable/soft proteins (that rapidly unfold) with a high concentration c. stable/hard proteins with a high concentration d. ions (if material is electrostatically charged) e. they all adsorb at the same rate

Option E, They all adsorb at the same rate

Explanation:

The following properties of bio-material surface influence the  intake of proteins, ions, and other metallic and non-metallic ion or molecule.

a) geometric - the surface area of substrate makes an impact while interacting with proteins. Those surface areas that have  grooves or pores provide greater surface area for interaction

b) chemical - chemical composition of functional species determine whether they will interact with with biomolecules or not

c) electrical - Like wise ionized surface of bio material prefer charged  substrate for interaction

Thus, bio-material will absorb all the bio- material at the same based on the type of bio-material and the substrate.

Hence, option E is correct

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
