BiochemistryChapters 2-5Ch. 2 Chemistry ReviewKnow chemistry vocabulary (review packet)Difference between types of bonds and how many bonds elements form (CHNOPS)hydrogen (weak bonds between molecules)ionic (lose electron)covalent (share electrons)polar v. nonpolar moleculesCh. 3 Waterpolar molecule...results in v shapeknow properties of water (cohesion, adhesion, surface tension)high heat capacitysolid less dense than liquid (ice floats)

know differences between solution, solute, solvent, aqueous solution; hydrophilic and hydrophobicWater is an excellent solvent. Ionic and polar substances dissolve easily in waternonpolar substances do not dissolve in water

Acids, bases, pH and buffers

**Think about all of these concepts in terms of living systems. How do all of these concepts allow a living organism to function? or cause an organism to not function successfully?Ch. 4I
