Hydrolytic enzymes which act on low pH are called as
The correct option is (C) : Hydrolases
Protein, lipid, nucleic acid, carbohydrate, and fat molecules are disassembled into their most basic components by hydrolytic enzymes. Hydrolytic enzymes include all digestive enzymes. Due to the release of HCl, the pH of the stomach is low. Protease, a protein-digesting enzyme, operates in low pH environments, such as the stomach. Since the stomach is not where carbohydrates are digested, amylase is a starch (carbohydrate) digestion enzyme.

Digestion can be defined as the process of breakdown of large, insoluble and complex food molecules into smaller ones for its absorption and circulation in the body. This process involves the usage of a variety of digestive fluids and enzymes, including saliva, mucus, bile and hydrochloric acid, among others.

The alimentary canal is mainly referred to as the pathway by which food enters our body and moves out through the anus after digestion. It is a tube-like structure that starts from the mouth and ends in the anus. The alimentary canal plays a primary role in human digestion and is also termed as the digestive tract.
Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract.
