Document Summary
The basis for life (what are microbes doing?) Respond and adapt to the external environment. Homeostasis (maintaining internal organization and order, usually by expending energy) Polypeptides are formed from the subunits amino acids. They make up 50 to 55% of the dry weight of the (cid:272)ell. The(cid:455)"re e(cid:374)z(cid:455)(cid:373)es that (cid:272)atal(cid:455)ze the (cid:448)ast (cid:373)ajorit(cid:455) of (cid:271)io(cid:272)he(cid:373)i(cid:272)al rea(cid:272)tio(cid:374)s i(cid:374) the (cid:272)ell. Nucleic acids are formed from the subunits deoxyribonucleotides which make up 2-5% dry weight of the cell and provide the instructions for assembly and reproduction of the cell. Ribonucleotides are another subunit of nucleic acids that compose 15-20% dry weight of the cell and have many functions, most of which are involved in the production of polypeptides. Lipids are formed many different structures as the subunits and make up about 10% dry weight of the cell. Their structural function is to make up cellular membranes that form physical boundary between the inside of cell and surroundings and membranes of internal organelles.
