Document Summary
Molecular size and lipid solubility: small nonpolar molecules (o2 and co2) are soluble in hydrophobic core of the membrane, small polar uncharged molecules (h2o and glycerol) are able to too. Response pathway activated by g protein coupled receptors: receptors bind first messenger, receptors activates g protein by causing gtp to replace gdp, g protein activates effector, effector produces second messenger(s, second messenger(s) activates protein kinase, leads to cellular response. Reactions of glycolysis: glucose receives phosphate group from atp, producing glucose 6 phosphate, glucose 6 phosphare is rearranged into its isomers, fructose 6 phosphate (phosphorylation reaction) (isomerization reaction, another phosphate group derived from atp is attached to fructose 6 phoshate, producing fructose 1, 6 bisphsophate (phosphorylation reaction, fructose 1, 6 bisphoshate is split into g3p and dap (hydrolysis reaction, dap is converted into g3p (isomerization reaction, two electrons and two protons are released from gdp to produce.
