An electolytic cell is filled with water. Which of the folowing will move toward the cathode? A)H+ ions B)O2- ions C) Electrons
In the electrolytic cell, ionic compounds are broken up into their parts: cations (+) and anions(-). The cations move twoards the cathode and the anions move towards the anode. H+ are postive and so are elctrons so they both migrate toward the cathode. Plus, electrons flow to cathode in all cell types. So the right answer is A) and C). B) is wrong because it's a anion which would make it move towards the anode.
Describe the difference between competitive inhibitors and noncompetitive inhibitors.
Competitive inhbitors- something compete for active site; can be overcome with substrate Noncompetitive or allosteric inhibitors- attaches at allosteric site and changes shape of enzyme so it is not functional; cannot be overcome with substrate because the shape is changed,
Describe what is happening at the Na+ and K+ gates during an action potential.
In summary, there are 4 steps in an action potential. 1)Rest-all gates are closed 2)Depolarization-Na+gates open 3)Repolarization-Na+ gates inactivate and K+ gates open 4)Hyperpolarization- All gates closed
