Question

Some students conduct an investigation in a biology lab by setting up four different artificial stomachs, each in a

40 °C water bath. The students place the same amount of boiled egg white, a protein-rich source, in each stomach.
They also add dilute hydrochloric acid, HCl, and pepsin, a digestive enzyme, to each stomach, as shown in the table.
The students observe the mass of egg white in each stomach every 15 minutes.
Which statement describes the most likely result of this investigation?
A. The mass of the Egg white increases as the volume of the enzyme increases.
B. The egg white is unaffected by the differing amount of enzyme.
C. Digestion decreases in each stomach as more of the egg white's surface area becomes exposed.
D. Digestion increases as the volume of the enzyme increases.

Answer 1

Answer: The answer would be D!!

Step-by-step explanation:

Answer 2

Answer: D. Digestion increases as the volume of the enzyme increases.

Step-by-step explanation:

Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster.

Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase.
