Final answer:
Amylase is the enzyme involved in carbohydrate digestion, breaking down starches into simpler sugars. Lipase, trypin, and pepsin are responsible for the digestion of fats and proteins, respectively.
Step-by-step explanation:
The correct answer to the question of which enzyme is involved in carbohydrate digestion is amylase. Amylase is an enzyme present in saliva and the pancreas, known as salivary amylase and pancreatic amylase, respectively. Its primary function is to break down starches and glycogen, which are complex carbohydrates, into simpler sugars like glucose. This process starts in the mouth and continues in the small intestine.
On the other hand, enzymes like lipase are responsible for fat digestion, whereas trypsin and pepsin are involved in protein digestion. These enzymes work in different parts of the digestive system, with trypsin being produced in the pancreas and pepsin in the stomach.
