The enzyme ptyalin helps digest carbohydrates, while the enzyme pepsin helps digest proteins.
What prevents ptyalin and pepsin from digesting the same type of food?
Choose 1

(Choice A)
A
They require a different number of molecules to react.

(Choice B)
B
They have different shapes.

(Choice C)
C
One is a protein and the other is a carbohydrate.

(Choice D)
D
They have the same amino acids chain.

b they have a difrent shape

Explanation:

Ptyalin and Trypsin cannot both digest the same type of food because enzymes are specific to a particular substrate due to their shape. Chemical catalysts such as Amylase lower the activation energy of a chemical reaction in order to increase the reaction rate.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
