Task 2: Concepts to Explore Further

1. Enzyme Regulation Mechanisms: I’d like to understand more about the specific mechanisms by which enzymes are regulated in biological systems, such as allosteric regulation or post-translational modifications.
2. Drug Targeting and Delivery: I’m curious about the methods and technologies used in designing and delivering drugs at the molecular level, especially in the context of personalized medicine.

Task 1: Exam Question

Question: How does a change in pH affect the activity of enzymes in biological systems, and what role does acid-base chemistry play in this process?

Answer: Enzymes are sensitive to changes in pH because they contain specific amino acid residues that can be protonated or deprotonated depending on the pH of their environment. These changes in protonation states can affect the enzyme’s active site, substrate binding, and catalytic activity. Acid-base chemistry is crucial in understanding this phenomenon as it involves the transfer of protons (H+) and their impact on the enzyme’s functionality. When the pH deviates from the enzyme’s optimal pH range, its activity can be significantly reduced or completely inhibited, which has important implications in various biological processes.
