Question

The diagram shows an experiment on the digestion of the protein in egg albumen by protease.

Answer 1

Answer:

C. containing

• egg albumen
• protease
• dilute  hydrochloric  acid

Explanation:

A protease is a kind of peptidase enzyme that breaks down proteins into peptide molecules. As a digestive enzyme it is located in the lining of the stomach where, relative to the hydrochloric acid in digestive juices, the pH is usually low/ acidic.

Enzymes speed up reaction rates by providing alternative pathways. By modifying the enzyme composition, supplying more collision energy, and changing the collisions between and the ratio of reactants, certain variables will increase the reaction rate.

Proteases function well at 37℃, the typical internal temperature of the human body- this temperature provides adequate energy for the reaction. Similarly, proteases require low pH for the correct configuration, and beyond this pH and temperature, they may become denatured or simply not function well as catalysts.
