Biological molecules are macromolecules, which basically means they are polymers composed on small repeating units that have been covalently bonded together. The exception to this is a type of lipid called triacyleglycerides or phospholipids which are relatively large molecules composed of smaller molecules bonded together. Subunits are chemically liked together in the cell by a…
Complement Protein: special proteins that expand/puncture the pores in membranes on foreign microbes allowing extracellular fluid to rush in and lyse the cells, thus killing them. Lymphocytes: specialized white blood cells T-cells: produced in the bone marrow and stored in the thymus. Act in a seek and destroy fashion by recognizing the antigen markers on…
