Document Summary
Defining life, presence of: cells metabolism (energy) reproduction respond to stimuli complex/organized/order dynamic growth and development evolution living organisms are composed of both organic and inorganic molecules. Organic molecules are defined as any compound that contains a significant amount of carbon. Hydrocarbons are the simplest type of organic molecule (ex. Attaching other atoms or groups of atoms to hydrocarbons results in new organic molecules with different chemical properties (an alcohol at the end of ethane ethanol) There are four classes of small biomolecules (monomers) (1) amino acids: catalysts and structural elements, polymer- proteins. A pentapeptide is made up of 5 amino acids. Polypeptides fold into unique 3d structures, resulting (hopefully) in a functional protein. The organelle responsible for synthesizing polypeptides is the ribosome (2) sugars: energy sources and structural elements, polymer- carbohydrates. Glycogen is an important polysaccharide for animals and it is made up of glucose which is a monosaccharide.
