Unformatted text preview: Know the differences between positive delta G and negative delta G Activation energyspace between the main line and the tip of the wavelength- non- spontaneous reactionpositive Space between the main and the bottom space of the wavelength- spontaneous reaction. Doesnt have activation energynegative Secondary transport (Pg. 99) - does not use ATP directlyuses it indirectly. Runs off the concentration gradient. Primary transport (Pg. 99) Antiport- opposite ways of molecules going out of the cell Symport- molecules that do through the cell in one direction. Pg. 100: Ex of sodium potassium pump that is hooked to the glucose pumpsymport uses the concentration gradient because the things that are on the outside that want to go in, bind with the glucose. When is a primary secondary or transport complex or important? Does a secondary transport directly use energy? No Acids: proton donor Base: proton acceptor Know the difference between polar and non-polar bonds Polar- the unequal sharing of electronsmost common example is waterH20, oxygen that has 2 covalent electronshydrogen has one covalent electron. Pg. 23- table of electronegativies. Oxygen is 3.5 and hydrogen is 2.1compare the twothey are not very close because oxygen holds on to more of the electrons.very close because oxygen holds on to more of the electrons....
