Verified step by step guidance

Begin by understanding the role of enzymes in the digestive system. Enzymes are biological catalysts that speed up chemical reactions, including the breakdown of food into absorbable nutrients.

Identify the function of each option provided: Glycogen is a stored form of glucose in the liver and muscles, not an enzyme. Insulin is a hormone that regulates blood sugar levels, not involved in digestion directly. Bile is a substance produced by the liver that helps emulsify fats, but it is not an enzyme.

Focus on Amylase, which is the correct answer. Amylase is an enzyme that specifically breaks down carbohydrates, such as starch, into simpler sugars like maltose and glucose.

Understand where amylase is produced and active: Amylase is produced in the salivary glands and the pancreas. Salivary amylase begins the digestion of carbohydrates in the mouth, while pancreatic amylase continues this process in the small intestine.

Conclude by summarizing the importance of amylase in the digestive system: Amylase plays a crucial role in the efficient digestion of carbohydrates, allowing the body to utilize these nutrients for energy.
