The best answer is B - Proteins.
Proteins make up enzymes, or to put it another way enzymes are made up of protein. It is enzymes that speed up the chemical reactions. Enzymes are organic catalysts, substances that speed up a (biochemical) reaction but do not take part in the reaction and remain unchanged at the end of the reaction.
In man, there are many enzymes. The majority of these are found in the digestive system where they greatly aid the process of food breakdown from complex molecules to simple molecules. Examples include salivary amylase found in saliva, which begins the gradual breaking down of starch into glucose right from the moment food is placed in the mouth and mixed with saliva. Pepsin in the stomach breaks down protein.
Bison just like cows eat grass and are known as herbivores.
<h3>What are herbivores?</h3>
Herbivores are animals which eat grass or plants as their food.
Herbivores are primary consumers since they obtain their food from the primary producers, plants.
Examples of herbivores are cows, goats, and bisons.
Therefore, since bison eat grass just like cows, bosons are herbivores.
