The correct answer is A. Proteins.
Pepsin is a digestive enzyme that breaks down proteins into smaller peptides and amino acids. It is produced in the stomach and is activated by hydrochloric acid. Pepsin is essential for the digestion of protein-rich foods such as meat, poultry, fish, eggs, and dairy products.
Starch is a complex carbohydrate that is broken down into glucose by the enzyme amylase. Amylase is produced in the salivary glands and pancreas. Glucose is the body’s main source of energy.
Carbohydrates are a type of nutrient that provides the body with energy. They are found in foods such as bread, pasta, rice, potatoes, and fruits. Carbohydrates are broken down into glucose, which is then used by the body for energy.
Fats are a type of nutrient that provides the body with energy and helps to absorb vitamins. They are found in foods such as butter, oil, meat, and dairy products. Fats are broken down into fatty acids, which are then used by the body for energy.
