LIVING FEATURES: eestructura, metabolism, growth, adaptation, irritability, reproduction, and organization homeotasis METABOLISM: sum of functions is divided into anabolism and catabolism anabolism: synthesis or construction of CATABOLISM matter: matter degradation REPRODUCTION: continuation of the species EVOLUTION: HOMEOSTASIS environmental adaptation: internal stabilityIrritable reaction is the ability of environmental stimuli homeotasis breaking MOLECULAR LEVEL: inorganic ? ? mineral salts in solution, structural ? SALES water in solution: are in the form of ions. ? positive cations, anions ? negative. STRUCTURAL SALES: they form structures within the body and are little or no soluble. WATER: • inorgnico more abundandande constituent of living beings • good solvent for ionic and polar substances • participating in chemical reactions as provider and acceptor Proton • formation of hydrogen • good thermoregulatorFUNCTIONAL GROUP is the part of the molecule that reacts and is characteristic paa each family or set of compounds existing compounds: • carbohydrates • proteins • lipids • CARBOHYDRATE nucleic acids are defined as polihidroxialdehidos and polihidroxicetonas ARE: • most abundant organic compounds in the biosphere and in turn the most diverse. • structural parts of plant and animal tissue also serves as: source of energy for all vital cell activities ARE CLASSIFIED IN:complex simplesy SIMPLE: Fast absorption of sugars and energy immediately. ? monosocarias ? glucose, complex sugars: sugars slower absorption and acts as backup power including: • ? disaccharide sucrose, galactose, fructus. • ? starch polysaccharides, cellulose, glycogen. ROLE: • energetic materials • Energy • warehouse involved in specialized functions in the composition of genetic material that controls heredity, reproduction, and government together to cellular proteins • antibodies and some hormones • as a structural material in plants, cellulose, and animals, hialluronico acid, are part of the intercellular space.
