Enzymes belong to the class of biological molecules known as proteins. They are specialized proteins that catalyze biochemical reactions in living organisms.
Class I MHC molecules present antigens to cytotoxic T-cells (which are CD3+CD8+).
Lipids belong to the class of organic compounds known as biomolecules. They are characterized by their hydrophobic nature and serve various functions in living organisms, such as energy storage, structural components of cell membranes, and signaling molecules.
Tigers belong to Class Mammalia.
Opossums belong to the class mammalia.
Glucose (I) is a monosaccharide (C). Sucrose (III) is a disaccharide (B) composed of glucose and fructose. Starch (II) is a polysaccharide (A) made up of multiple glucose units linked together.
It depends on what enzyme and what chemical you're talking about.In general, enzymes catalyze a certain reaction for a certain molecule or class of molecules. They do pretty much bupkis to any molecules outside that class.
They belong to the class Mammalia ( mammals).
