Incorrect Question 6 0 0.2 pts In Biology, a is a molecule that binds to a protein but is not changed by the protein enzyme 0.2 0.2 pts Question 7 In Biology, a substrate is a transmembrane protein. a molecule on which a protein acts that will be moved across a membrane, broken down, or otherwise changed by the protein in some way. It may also be the surface or material on which something lives or grows, but this is human physiology, not microbiology.

Solution

Answer:

1) Ligand is a molecule that bind to the protein. The ligand-protein interaction is imporant for the functional protein. On every protein having teritary structure, a binding site is present, where ligand binds with help of noncovalent intercations. Enzymes are made up of the proteins but not all proteins are enzymes, so enzyme is wrong.

2) Substrate can be a protein, carbohydrate and lipid. Every enzyme have a specific active site, where substrate bind to active site and break down of the substrate takes place. The substrate which is in form complex state is broken down into simplest form and energy is liberated. Substrate cannot be broken down into simple units in a single reaction, it involves step-by step process in presence of the enzyme.
