Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - 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 develop...

Discuss the following forces that are involved in the binding of substrates to enzyme: 1. electrostatic interactions 2. hydrogen bonds 3. van der Waals forces 4. hydrophobic forces Correct Answer-All of these interactions contribute to binding energy, increasing specificity of the substrate to enzyme binding. Each of these interactions need to be close in order to get significant binding (especially van der Waals, upon which this relies on). These reactions do not need to be as precise, just...

Catalyst - ANSWER-a substance that increases the rate of a chemical reaction without being consumed Enzyme - ANSWER-a molecule that increases the rate of a chemical reaction without being consumed (ex: protein) Activation energy - ANSWER-amount of energy required to convert a substrate into a product Active site - ANSWER-location on an enzyme that physically interacts with the substrate How do enzymes catalyze reactions? - ANSWER-1. substrate attaches to active site 2. activation en...
