The enzymes found in intestinal juice finally convert

The correct answer is All of the above.

Intestinal juice (also known as succus entericus) is secreted by the walls of the small intestine. It contains a variety of enzymes that perform the final steps of digestion, converting complex biomolecules into their simplest, absorbable forms:
1. Carbohydrate Digestion: Enzymes like maltase, sucrase, and lactase break down disaccharides and complex carbohydrates into simple sugars, primarily glucose.
2. Protein Digestion: Peptidases (like enterokinase and dipeptidases) act on partially digested proteins (peptides) to convert them completely into amino acids.
3. Lipid/Fat Digestion: Intestinal lipase acts on emulsified fats, breaking them down into fatty acids and glycerol.

Since the enzymes in the intestinal juice carry out all these final conversions, all the given statements are correct.
