Lecture title - Membrane potential
5 important questions on Lecture title - Membrane potential
What is the membrane potential and why is it called membrane potential?
The term comes from the potential for the membrane to harness the electrical force of attraction between separated charges to perform work when they are permitted to come together.
Where do the attractive forces between the separated charges cause them to accumulate?
What 2 factors generates the resting membrane potential of a cell and what maintains the resting membrane potential
- The unequal distribution of key ions Na+, K+ & negatively charged (anionic) intracellular proteins, written as A-) between the ICF and the ECF
- the permability of a cell to a Ion. That Ion will influence the cells mV
RMP is maintained by Na+/K+ pumps & Na+ and K+ leak channels
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Sailabus. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Sailabus, which helped me to finish all of them within 3 months.
Because of Sailabus, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Sailabus, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Sailabus. Thanks so much!
Ever since I started studying with Sailabus I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Sailabus. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Sailabus.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Sailabus to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Sailabus to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Sailabus get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Sailabus made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with Sailabus, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Sailabus, I have passed all my courses on the first try. For me, Sailabus takes away the stress of wondering if I will pass or not.
Thanks to Sailabus, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
What is the relationship between the equilibrium constant of an ion and electrical & concentration gradient?
The steeper the concentration gradient is for an ion, the greater the ion’s equilibrium constant because a larger opposing electrical gradient would be required to counterbalance the steeper concentration gradient.
In a living cell with both Na+ and K+ what determines the cell’s equilibrium potential?
The greater the permeability of the plasma membrane for a given ion, the greater the tendency for that ion to drive the membrane potential toward the ion’s equilibrium potential.
Because most cells are more permeable to K+, K+ equilibrium constant influences the RMP more than Na+ does
