the cell membrane is paritally permable which only allows small molecules to enter.
carbohydrates , protein and fats in food are usually made out of large molecules that are too big to pass through the paritally permeable membrane.
thus the food mut be digested.]]> 2018-04-07 11:17:37 UTC https://padlet.com/rachellwongggg/science/wish/249416180 digestion rachellwongggg https://padlet.com/rachellwongggg/science/wish/249417113 is the breakdown of large molecules of food into small diffusible molecules.]]> 2018-04-07 11:32:23 UTC https://padlet.com/rachellwongggg/science/wish/249417113
