Those types of molecules are called enzymes.
When you eat, your body needs to digest the food and turn it into a form that the body can use for nutritional purposes. Digestion refers to the chemical breakdown of large food molecules into smaller molecules that can then be used by cells. This process occurs when certain enzymes are mixed with the food. One of those enzymes is pepsinogen, which is converted to pepsin; pepsin is important because it digests proteins.
Some compounds fall apart when heated. This is because the molecules breakdown with the added heat. Ionic compounds are an example of those that fall apart.
The Golgi Apparatus forms large molecules from smaller ones. It gathers simple molecules and combines them to form larger more complex molecules. From there is takes those larger molecules and packages them for transport.
Molecules move in and out of the cell by difffusion process and only those molecules which have size smaller then pore size of plasma membrane can move in and out of the cell. The second factor is ionic conc or is also known as conc gradient according to which molecules of required ionic status can move in and out of the cell
Digestion is the chemical and physical breakdown of food into compounds usable by the body. Absorbtion is the taking up of the compounds by the body. either through the stomach lining or through the intesitinal walls.
The term you are looking for is "absorption." Absorption is the process by which digested molecules and compounds, pass through the epithelial layer (the skin cells that line the inside of the digestive tract, as well as many other parts of the body) and into the circulatory system or, in the case of fats, the lymphatic system.
Molecules have properties that are different from those of the elements of which the molecules are composed.
Yes. There are much smaller measurements. 1 cc is a cubic centimeter; 1 cubic millimeter is 1000 times less volume. What is small to someone who works with food may be quite large for those who work with molecules
