Document Summary

Theory can be broken down into four steps: chemical evolution began with production of small organic compounds, simple organic compounds reacted to form mid-sized molecules called amino acids, sugars and nitrogenous bases. Moving the cell itself or for moving large molecules and other types of cargo inside the cell (actin and myosin) Act as signals that help coordinate the activities of many cells. Receive chemical signals from outside cell and initiate response. Provide support for cells and tissues; form structures such as hair, feathers, cocoons and spider webs. Keeps cells flexible and in their normal shape. Move substances across cell membrane and throughout body (haemoglobin) Miller experimented to see if complex organic compounds could be synthesized from simple molecules present in earth"s early atmosphere and ocean. Large glass flask containing methane, ammonia and hydrogen, all of which have high free energy.
