A+ GRADE. Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - Correct Answer -Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amino acid valine, leads to the...

Which property of enzymes is illustrated in the final step of the enzymatic cycle? Enzymes are specific. Enzymes increase the reaction rate for a reaction. Enzymes lower the activation energy for a reaction. Enzymes are reusable. - CORRECT ANSWERS Enzymes are reusable In the final step of the enzymatic cycle, the product is released and the enzyme is able to bind to a new substrate and begin the cycle again. In the enzyme cycle, which step immediately follows induced fit? Formation of t...

1. Competitive inhibitor - Ans a. Binds to the active site and prevents the substrate from binding b. -Adding more substrate would increase the rate of the reaction (can outcompete the inhibitor) c. -usually transition state analogs 2. Noncompetitive inhibitor - AnsSpecial case of the mixed inhibitor where it can allosterically bind to both the enzyme or enzyme-substrate complex with equal affinity -increasing substrate concentrations will not be able to affect rate 3. Uncompetitive in...
