Question

What is the correct order for the steps of digestion?

1. nutrients carried to cells
occurs second
2. fats converted to fatty acids
occurs first
3. proteins broken down to amino acids
occurs fourth
4. carbohydrates changed to sugar
occurs third

Answer 1

Correct order: 4 → 3 → 2 → 1.

So:
1st — carbohydrates changed to sugar (4)
2nd — proteins broken down to amino acids (3)
3rd — fats converted to fatty acids (2)
4th — nutrients carried to cells (1)

Explanation: carbohydrate digestion begins in the mouth, proteins mainly in the stomach, fats are largely digested in the small intestine, and absorption/transport of nutrients to cells occurs last.
