Define, describe or illustrate the following vocabulary terms and use the term in context in a sentence to make a. enantiomer (optical isomer) macromolecule polymer anabolism catabolism compartment prokaryotic cell eukaryotic cell adenosine triphosphate Central Dogma Atomic weight (mass) radioisotope Molecular weight molarity Valence electrons covalent bonds polar covalent bond nonpolar covalent bond ionic bonds hydrogen bonds Van der Waals interaction (bond) hydration shell pH acid base Main points about Overview- Chemical Bonds lecture: 1. Amongst the diversity of life there is at the cellular level evidence for common principles governing life. Whether they are prokaryotic or eukaryotic cells they share a common set of hydrocarbon-based biochemicals and use them in similar biochemical pathways for basic anabolism and catabolism, all use phospholipids bilayers to make the cellular compartments, have ATP for energy currency, use nucleic acid polymers for genetic information and must arise from a previous cell. 2. Only two basic types of cell exist: prokaryotic with few cell membranes and eukaryotic with multiple membrane-bounded organelles. Compartments make reactions more efficient by concentrating substances and avoiding non-productive interactions.
