-75 mV. During resting potential‚ the inside of the axon is negative GRADED POTENTIAL ACTION POTENTIAL Action potential is a fleeting reversal of the membrane potential‚ caused by changes in permeability of the plasma membrane of neuron to potassium and sodium ions causing an electrical impulse to be transmitted along the axon. When a stimulus depolarizes the membrane‚ a few of the voltage-gated sodium channels that are found in the neuronal plasma membrane open permitting sodium ions to

Experiment 3: Solution Calorimetry: Thermodynamics of Potassium Nitrate II. Abstract A determination of thermodynamic variables of KNO3 is presented. KNO3 was heated and dissolved in varying volumes of distilled water. Upon dissolution‚ the KNO3 solution was removed from heat and the temperature was recorded once crystals formed. For each solution‚ ∆G the Ksp were found with the temperature and molarity values. ∆H and ∆S were found through the linearization of the data with

Elucidating the mechanisms of these diseases will benefit medicine as a whole‚ not just patients with a particular disease. For instance‚ although the inherited long-QT syndrome is not common‚ identifying the underlying defects in the KVLQT1 and HERG potassium channels and the SCN5A sodium channels may benefit the study of ventricular arrhythmias‚ which are responsible for 50‚000 sudden deaths each year in the United States.

obvious. Instead‚ back titration will be employed. The titration of a reducing agent with iodine to produce iodide ion is referred to as an iodometric titration. Iodine is generate by adding a weighed amount of standard potassium iodate (KIO3) to an excess of potassium iodide (KI) and then add adding strong dilute sulphuric acid (H2SO4) to produce iodine as shown below: (1) KIO3(aq) + 5KI(aq) + 3H2SO4(aq) → 3I2(aq) + 3H2O(l) + 3K2SO4(aq) The known excess of I2 generated by the reaction
