Question

A mature lysosome has an internal pH of around 4.5. Using Figure 8.17b as a guide, draw a graph showing what you would predict for a lysosomal enzyme's reaction rate. Label its optimal pH, assuming its optimal pH matches its environment.

Short answer

The graph plotted between the rate of energy and pH tends to form a peak around the internal pH of 4.5. The peak formation takes place with the balance of internal pH to the pH of the surroundings.

Step-by-step solution

Description of lysosome

A lysosome is an organelle that digests biological substances. The additional cell parts are digested using the lysosomal enzymes. The major mechanism of lysosomes is to destroy the bacteria and viruses that invade the cell.

Description of enzyme

The biological catalyst present in the biological system that mediates the chemical reaction in the body is known as enzymes. The substrate gets converted into a product by binding to the enzyme at the active site.

Reaction rate of lysosomal enzyme                                  

The enzyme reaction is when the enzyme mediates the response to convert the reactant into products. The reaction rate of the enzyme is maximum at the optimal pH.

The lysosomal enzyme also has the maximum activity at the optimal pH. The pH of the enzyme matches the pH of the environment. The enzyme shows the maximum activity around pH 4.5.
