Understand the following enzymatic terms: substrate, enzyme, active site, induced fit, enzyme specificity, product, enzyme / substrate complex, cofactors and coenzymes

Expert Solution

Enzyme is a protein which involves in various reactions , enhancing the rate of the reaction but after the reaction it remains unchanged. The molecule on which enzyme works is called substrate. And by these work a new molecule is produced which is called product.

The active site of an enzyme is a small portion of the enzyme molecule What is the function of the rest of the huge molecule? Check all that apply. To pass through cell membranes. To provide sites for enzyme control and regulation. To hold the substrate in place. To stabilize the three-dimensional structure of the enzyme. To align the active-site functional groups that catalyze the reaction.

1. The active site of an enzyme usually consists of a pocket on the enzyme surface lined with the amino acid side chains necessary to bind the substrate and catalyze its chemical transformation. Carboxypeptidase, which sequentially removes the carboxyl-terminal amino acid residues from its peptide substrates, consists of a single chain of 307 amino acids. The two essential catalytic groups in the active site are furnished by Arg145 and Glu270 . a. How many amino acid residues apart are these...

3a. The catalytic mechanism of an enzyme involves nucleophilic attack on the substrate by an active site cysteine. Normally, this cysteine has a pKa of 8.2. If the cytoplasm of the cell is pH 7.2 and the pH of the mitochondrial matrix is 8.2, predict whether this enzyme is a better catalyst in the cytoplasm or mitochondria. Explain

1.When the substrates bind to the active of an enzyme, the active site changes shape. This is an example of: a) lock & key model; b) inhibitor model; c) allosteric model; d) induced fit model; e) none. 2. The change in free energy at equilibrium is: a) increased; b) decreased; c) no net change 3. You have a gram of each of the following: bacon grease, lean ground turkey and bread. Which on has more potential energy and why? a)...
