Q. 16.45 - An Introduction to General, Organic, and Biological Chemistry

Question

The following graph shows the activity versus$pH$ curves for pepsin, sucrase, and trypsin. Estimate the optimum $pH$ for each.

Step-by-Step Solution

Answer

Pepsin: The appropriate $pH$ for enzymatic activity in pepsin is $2$ as can be seen in graph.

Sucrase: The best $pH$for greatest activities in sucrose is $6$, as depicted in the graph.

Trypsin: And according to graph, the appropriate $pH$ for peak function in trypsin is $8$.

Step 1: Introduction.

Enzyme are quite functional at the optimal $pH$, while leaves protein's functional group unharmed. 

Step 2: Given data.

The interactions of the $pH$ groups are interrupted at larger or smaller $R$, resulting in lost of catalysis.

Curves for pepsin, sucrase, and trypsin, as well as their optimal $pH$, are used in the graph following table:

Step 3: Explanation.

Pepsin: The best $pH$ for profound influence in pepsin is $2$, seen in the graph.

Sucrase: The ideal $pH$ for highest activities in sucrose is $6$, as demonstrated in the graph.

Trypsin: Per the graph, the ideal $pH$ for peak activity in trypsin is $8$.
