Document Summary
Five properties that are shared by all livin g things: cellular organization, energy transformations, maintenance of internal environment, reproduction & growth, evolution. Living things consist of one or more cells. In multicellular organisms, cells form tissues, tissues form organs, organs form systems. Have a blueprint of their characteristics (dna in genes) Produce new cells or new product within cells. With consistent confirmation, lack of exceptions, and time, a hypothesis may become a theory. New information and new techniques may eventually disprove what is currently accepted. Competing explanations can be disproved leaving one explanation that wins out. Why study biological chemistry: we are carbon-based organisms made up of many macromolecules found in all living things, our cells contain molecules and enzymes involved in chemical reactions, water is essential for life. Most important cell molecules are based on carbon. Carbon can form 4 covalent bonds with other molecules. Four broad groups of biological macromolecules: carbohydrates, lipids-fats, proteins, nucleic acids.
