Homework Answers
Qn A.
Qn B.
Best pH for highest enzyme activity for this organism is 10.
This is the optimal pH. Optimal pH is the pH at which enzymes shows its highest activity.
Qn C.
If the organism exposed to pH of 6, enzyme activity would decrease.
Because enzymes shows its highest activity at optimal pH. Means it catalyzes the reaction at a particular H+ ion concentration. When the pH changes H+ ion concentration also change. H+ concentration higher or lower than optimal level decreases the enzyme activity. One unit pH change leads to change in hydrogen ion concentration by 10 folds.
At pH 1 hydrogen ion concentration is 1M.
At pH 10 H+ has the concentration of 0.0000000001M. At pH 6 H+ concentration is 0.000001 M.
pH 6 has more hydrogen ion concentration than pH 10. So, at pH 6 (which is lower than optimal pH 10) the enzyme activity decreases.

Nursing Facilities Case: Mary Mary is a resident in a nursing facility—and has been for the past 5 of her 87 years. Most of the time, she is withdrawn into her own little world, although she shows occasional signs of being alert to her surroundings, sometimes appearing to be confused by them. Her physical appearance is generally good. She is neat and clean, more due to the care and effort of the facility staff than to her own efforts. Her...
