Amphibolic

The term amphibolic (Greek: amphi meaning “both sides”) is used to describe a biochemical pathway that involves both catabolism (A degradative phase of metabolism in which large molecule are converted into smaller and simpler molecule,which is reaction involve two type. First, hydrolysis reactions, in this reaction catabolism is the breaking apart of molecules to smaller molecules to release energy. An example of a catabolic reaction is digestion and cellular respiration where you break apart sugars and fats for energy. Hydrolysis is the way in which this is done and it is basically the reverse of a dehydration reaction. Breaking down a protein into amino acids or a triglyceride into fatty acids or a disaccharide into monosaccharides are all hydrolysis or catabolic reactions. Second, oxidation reactions involve the removal of hydrogens and electrons from an organic molecule)and anabolism(the biosynthesis phase of metabolism in which smaller simple precursor are converted to large and complex molecule of the cell. Anabolism reactant found in two type,which are dehydration synthesis reaction,in this type involve the joining of smaller molecules together to form larger, more complex molecules. This occurs through dehydration synthesis reactions. These are the most common ways smaller organic molecules can be formed into more complex ones and applies to the formation of carbs, proteins, lipids and nucleic acids. Other type called reduction reaction,which involves the adding of hydrogens and electrons to a molecule. Whenever you do that, it gains calories of energy because when you split a hydrocarbon bond, it releases energy).
