It depends on what change this is. If this is visible change, it may not be detected. Otherwise, heat does change substances in terms of kinetic energy of molecules in a body or average distance between the molecules of the body.
Antigens is the term for molecules that are foreign to the body.
I suppose that you think to metabolism.
Antigens Antibodies neutralize these molecules.
The process by which food substances are chemically changed into simpler forms that can be absorbed is called digestion. This process involves the breakdown of complex molecules into smaller molecules that can be transported and utilized by the body for energy and nutrition.
Epithelial tissue is a type of cell tissue that can absorb and secrete substances. This tissue covers the surfaces of the body and internal organs, forming barriers that can facilitate the movement of molecules in and out of the body.
Water is a dipolar molecule, as the hydrogen molecules have a slight positive charge and vice versa for oxygen, this means that polar and ionic substances (which also have charges) attract the hydrogen or oxygen molecules and form a bond with them. When many many water molecules surround one atom of the substance they break the bonds in the substance causing the substance to dissolve, this happens to substances like glucose. This therefore means that polar and ionic substances can dissolve into the blood plasma which is largely composed of water and be transported all around the body in the blood stream.
The digestive system is responsible for producing enzymes that aid in breaking down substances for absorption. These enzymes help to break down food into smaller molecules that can be absorbed by the body for growth and repair.
The presence of enzymes can determine the concentrations of other substances in the body. Enzymes regulate biochemical reactions by speeding them up. The presence or absence of specific enzymes can influence the rates of reactions that produce or break down certain molecules, thereby affecting their concentrations in the body.
During the process of detoxification and metabolism, substances such as drugs, alcohol, and toxins pass through the liver. The liver breaks down these substances into smaller molecules that can be eliminated from the body.
