Document Summary

What does the cell put an enormous amount of. Level 1: small organic molecules (glucose, aa, nucleotides) Level 3: supra-molecular structures (cell wall, membrane, chromosome) Level 4: organelles, other structures (chloroplast, mitochondria, nucleus) Define: electronegativity, polar covalent bond, hydrogen bond (w/ examples) Phosphorus ~1. 1: most abundant (99%): h, c, n, o. Blue (0. 9%): na, mg, k, ca, p, s, cl. Green (req. in trace amounts): v, cr, mn, fe, co, cu, zn, se, mo, i, f. Yellow (undetermined if essential): b, si, ni: strong bonds formed by sharing e- b/w adj. atoms, can be polar/non-polar, weak interactions. Double bond = 2 e- pairs shared + no free rotation about bond axis. Inefficiency warms body, not too warm b/c of h2o"s high specific heat: at 37 degrees c, ~15% of h2o molecules joined to 4 others, when every h2o molecule forms 4 h bonds (max) = crystal lattice forms (ice)
