They are converted to end products that are soluble and can easily pass through cell membranes.

Explanation:

All the foods we eat are made up of three types of macronutrients: carbohydrates, proteins and fats. They are responsible for producing energy for the functioning of the organism and providing the basic compounds for the construction and repair of tissues. Carbohydrates are naturally present in vegetables, fruits, grains and in milk, and are important sources of energy for the functioning of the body. Proteins are sources of energy, amino acids and other compounds used in the synthesis of many substances in the body. Almost all foods contain proteins, as they make up the cells of animals and plants. Fat, in turn, is an important nutrient for the functioning of the body. In addition to providing essential fatty acids, it is a good source of energy and an effective vehicle for the absorption of fat-soluble vitamins.

When most proteins, fats and carbohydrates are digested completely, they are converted into final products that are soluble and can easily pass through cell membranes, through specific proteins that allow substances to enter and exit the cell.
