Verified step by step guidance

Begin by identifying the primary function of each organ listed in the options. The stomach is primarily involved in mechanical digestion and the initial stages of protein digestion through the enzyme pepsin.

Consider the role of the liver. The liver is crucial for metabolism, detoxification, and the production of bile, which aids in the digestion of fats, but it does not produce digestive enzymes directly.

Evaluate the function of the gallbladder. The gallbladder stores bile produced by the liver, releasing it into the small intestine to help emulsify fats, but it does not produce enzymes.

Focus on the pancreas. The pancreas plays a key role in digestion by producing a variety of enzymes, such as amylase, lipase, and proteases, which are released into the small intestine to digest carbohydrates, fats, and proteins.

Conclude that the pancreas is the organ responsible for producing enzymes that digest energy-providing nutrients, making it the correct answer.
