saliva contains digestive enzymes to begin digesting:
cholesterol
protein
carbohydrates
fats

Explanation:

• First question: Nutrients include macronutrients (proteins, carbohydrates, fats) and micronutrients (minerals like sodium). Glucose is a simple sugar (a monosaccharide) that is a building - block of carbohydrates, but it is not classified as a separate nutrient category.
• Second question: Saliva contains salivary amylase (ptyalin), which begins the digestion of carbohydrates. Cholesterol is a lipid, protein digestion starts in the stomach (pepsin), and fat digestion mainly occurs in the small intestine (pancreatic lipase).

Answer:

• First question: glucose
• Second question: carbohydrates
