cohesion - Attraction between molecules of the same substance adhesion - An attraction between molecules of different substances covalent - A chemical bond that involves sharing a pair of electrons between atoms in a molecule hydrogen bond - A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule. polar - Having a pair of equal and opposite charges. biochemistry - Chemistry dealing with chemical compounds and processes in living plants and animals activation energy - Energy needed to get a reaction started ph scale - Which of the following processes is regulated primarily by the buffering action of proteins?, measurement system used to indicate the concentration of hydrogen ions (H+) in solution; ranges from 0 to 14
acidic - Aspartic Acid macromolecule - A very large organic molecule composed of many smaller molecules basic - Arginine carbohydrate - CHO - stored in the bosy as glycogen in the live and muslces, where it eventually is broken down into glucose. Primary source of heat and energy - basic building blocks. nucleic acid - (biochemistry) any of various macromolecules composed of nucleotid chains that are vital constituents of all living cells protein - An organic compound that is made of one or more chains of amino acids and that is a principal component of all cells lipid - Fats enzyme - A type of protein that speeds up a chemical reaction in a living thing catalyse -
substrate - A specific reactant acted upon by an enzyme digestive system - Breaks down food into absorbable units that enter the blood for distribution to body cells. lysosome - An organelle containing digestive enzymes ionic - Formed when one or more electrons are transferred from one atom to another
