BIS 102 Chapter Notes - Chapter 1 (all): Living Systems, Lysogenic Cycle, Nucleoid
Document Summary
Learning objectives: basic chemistry of biomolecular composition, macromolecular structure and function, cell types/organizations, definition of a virus. Biomolecules (cellular constitutes) must conform to chemical and physical properties that govern all matter. Organization (largest to smaller) cells organelles macromolecules: organelles subcellular structures, complex assemblies of very large polymeric molecules, macromolecules composed of simple sets of chemical building blocks, ie. sugars and amino acids. Conformation complex 3-d structure of macromolecule (consequence of interactions between monomeric units, influenced by individual chemical properties) Biological structures play a role in organism"s existence (biological purpose, ie. enzymes part of metabolism) Ability to extract energy from environment directly effects the ability to maintain structure and activity level (ultimate source of energy = sun) Biosphere system through which energy flows: organisms capture energy by forming biomolecules such as atp and nadph (these represent chemically useful forms of stored energy.
