How do the nutrients that enter our cells compare with the food we eat

The food we eat is broken down into individual, microscopic nutrient molecules which enter the cell.

The food we eat are very complex and insoluble. The nutrients that enters our cells are simple and soluble, this is because they have been through different digestion processes, include both physical and chemical digestions. For example, different enzymes are used to break down those complex food molecules into simpler forms, and they can then be absorbed into the blood to be assimilated with our body cells to perform their functions.
