We're usually just told that exercise is a great way to stimulate the movement of glucose into cells. But how does it do that? I would think that insulin resistance is insulin resistance, exercise or no exercise.
I am trying to conceptually understand this relationship. One thing that's not helping is I keep hearing the phrase "the resting length" of muscle. It's using the word "THE" as if there is one resting length. This phrase implies that the length stays the same no matter how bent my elbow is at...
Thank you atyy. With that excellent link you directed me to and your explanations, I now understand all of this...at least, for a system of Na+ and K+. I am not going to think of how Cl- would fit in the mix anytime soon (don't know if it will complicate things to a great extent). Thanks, again.
Oops. I was thinking in terms of "final state" rather than "steady state". So if a steady state was not maintained and the concentrations of the two ions in one compartment was not maintained relative to those in the other compartment, would membrane potential decline towards zero as a function...
The equilibrium potential between the two compartments, not between the two cationic species. My confusion comes from reading this paragraph in my textbook:
Why does making relative permeability go from equal to not equal make the equilibrium potential (the potential between the two...
It seems to me that change in permeability should not shift the equilibrium of entering and exiting ions, except how fast equilibrium is reached. Consider this: two compartments are separated by a membrane. 1st compartment holds 1mM Na+ and 10mM K+ and 2nd one holds 10mM Na+ and 1mM K+.
Let's...
So, what you are saying is that thermal energy is the driving force of potassium ions against the electrical gradient. Correct?
Edit: The problem with the container explanation is that it is not applicable to cells, I think. I would assume that the concentration of OVERALL molecules inside a...
But how can concentration gradient counteract electrical force? Concentration gradient is not really a force; it is only random collisions leading ions from higher concentration to lower concentration by probability alone. How can random movement oppose electrical pull? This is the concept I am...
In terms of neurons, the outside is more positive than the inside. Thus, a potassium ion trying to make an escape (due to it's concentration gradient) should be deflected/repelled back into the neuron. Those ions should be bounced back in when they reach close to the surface. But since not, this...
The rate law in question is not something I got from anywhere. I just used my previous knowledge of formulating rate laws and applied it in this situation. From consulting many textbooks, they introduce equilibrium constant and it's relation to the rate law for gases, but solubility product...
