If helpful pls mark as brainliest

Explanation:

Lipids, or fat, go undigested in your digestive tract until they reach your small intestine, where they meet bile. Bile contains bile salts, which act as an emulsifier of lipids. This breaks the large fat droplets into smaller droplets that are then easier for the fat-digesting enzyme pancreatic lipase to digest Pepsin is the active protein-digesting enzyme of the stomach. Pepsin acts on protein molecules by breaking the peptide bonds that hold the molecules together. Digestion of protein is completed in the small intestine by the pancreatic enzymes trypsin, chymotrypsin, and carboxypeptidase.

Answer 2

1. sac-like digestive system

• A sac-like digestive system has a single opening. Food travels into it through that, gets digested and excreta comes out of the same opening. For example, Platyhelminthes. This is also known as a digestive cavity.

1. Tube-like digestive system

• In a tube-like digestive system there are two openings. The food enters through one, gets digested and moves out of the other one in the form of excreta, after the digestion is done. Human beings have this type of a digestive system. this is also known as a digestive tract.
