Enzyme Regulation

Question 1

Explain the effects of pH on protein function

Give an example

Answer 1

1. Amino acids make up proteins
2. These amino acid have side chains which become protonated or deprotonated
3. This influences the interactions within a protein i.e. tertiary structure
4. This leads to changes in protein shape, rigidity and therefore function

Protein called talin links actin cytoskeleton to integrin adhesions on a plasma membrane. The lower pH upregulates the function of talin and thus moves cells faster along a cell EHHHH better expl please

Question 2

How does temperature influence enzyme activity

Answer 2

1. Trend increases activity until denaturing occurs
2. But not all enzymes since some exist and adapted in either hot or very cold environments
