Question text WORKSHOP QUESTION a) Fill in the blanks using only the following terms.Note: You can enter the terms as plurals if desired, but the singular version will work even if not grammatically correct. Some terms may be used multiple times and some not at all. All terms must be spelled correctly to be marked correctCH3, ionic bond, outside, hydrogen bond, amino, primary, hydrophilic, covalent bond, OH, carboxyl, peptide bond, secondary, CH3OH, hydrophobic, tertiary, R-group, inside, hydrogen bond, quaternary1. The bond connecting the Answer 1 Question 21[input] group to the COOH group between adjacent amino acids is called a Answer 2 Question 21[input].2. The formation of local coils and sheets, which constitute a protein's Answer 3 Question 21[input] structure is determined by formation of a/an Answer 4 Question 21[input] between the backbones of amino acids.3. The complex tertiary structure could be formed by hydrophobic amino acids orienting towards the Answer 5 Question 21[input] of the protein. Electrically charged residues are also likely to interact via a/an Answer 6 Question 21[input].b) You are testing the properties of a new enzyme. In order for the particular enzyme to be cost effective you require a minimum rate of enzyme activity to be greater than 30 mg/ml of product per hour, within the first 2 hours of the reaction (this can be calculated by subtracting the lower product concentration from the higher product concentration divided by the time elapsed over the first 2 hours).After carefully examining the graphs above, which settings of the following conditions in isolation would allow you to meet your requirement (if no tested condition can meet the threshold, enter NA below):1. Adjustment of the pH to Answer 7 Question 21[input].2. Temperature at Answer 8 Question 21[input]°C (do not include the units of measurement).3. Inclusion of Answer 9 Question 21[input] metal ions.4. Presence of Answer 10 Question 21[input] activator.
