Document Summary
How do we define life: metabolism, growth, reproduction, genetic variation/evolution, response/adaptation to the external environment, homeostasis maintaining internal organization and order, usually by expending energy. What are the macromolecules (major building blocks) needed for life: polypeptides. Enzymes catalyze the vast majority of biochemical reactions in the cell. Other proteins are structural components of cells. Can serve many purposes, but one of the most important is the function of enzymes as catalysts of chemical reaction. Located in the cytoplasm of bacteria and archaeons, nucleus of eukarya. Functions in conversion of glycogen into glucose monomers. Functions in the passive transport of k+ across the membrane, from an area of high concentration to an area of low concentration. Functions in active transport o na+ and k+ across the membrane, from areas of low concentration to areas of high concentration. Functions in polymerization of monomers to form flagellum, which aids in bacterial motility. Key component of cell division machinery: nucleic acids.
