The positive inside rule is a general rule for membrane proteins. Because of the mechanism involved in transmembrane domain insertion (regions of the protein which cross the membrane), membrane proteins tend to have more residues which can take on a positive charge on the inside of their cells. So, almost all, if not all membrane proteins have more solvent exposed Lysine and Arginine residues on the sides of the transmembrane domains which rest inside of the cell in comparison to the number which rest on the outside of the cell.

Is the nucleus of there atoms positive negative or neutral?
inside the nucleus there are protons which are positive and neutrons that are neutral, because the neutrons are neutral they don't affect the charge. so the Nucleus is Positive.
What is the major positive ion outside of cells?
Sodium is the major positive ion outside the cell. Potassium is the major positive ion inside the cell.
What is the charge on barium is it cation or anion?
Barium is an alkaline-earth metal, which means it has two valence electrons. To fulfill the octet rule (see below), it wants to lose those two electrons. When it does this, the number of positive protons is greater than the negative electrons; the ion is positive. Positive ions are called anions.
What condition is neuron in when the outside of the neuron has a net positive charge and the inside has net negative charge?
This is called the resting potential (inactive state) of the neuron. However, when a neurotransmitter binds to receptors, electrical stimulus is applied, etc. to induce an opening of ion channels in the membrane of the neuron, positive ions rush into the neuron from the outside to the inside, and result in a sharp increase of the positive charge density (due to more positive ions) inside the neuron. Beyond a certain threshold, this can induce the creation of an action potential, causing the neuron to fire. After the action potential is created, and the neuron fires, there is a short refractory period where the neuron cannot be fired again due to stimuli, when positive ions are pumped back out of the neuron, negative ions are brought into the neuron, and then the ion channels close, leaving the neuron in a polarized state, and returning it to a resting potential.
When was the octet rule invented?
Although it was a slow process involving numerous years of research and chemists, in 1919 Irving Langmuir refined the concept into the cubical octet atom and octet theory. This octet theory evolved into what is now known as the octet rule.
What is the rule for adding integers with like signs?
positive + positive = positive negitive + negitive = positive negitive + positive = negitive
Is the interchange rule in AFL going to be positive?
No.
What is the rule for subtracting positive numbers?
Never.
What are the ten rules of The Power of the Positive Thinking?
The book "The Power of Positive Thinking" by Norman Vincent Peale emphasizes ten principles including believing in yourself, setting goals, staying persistent, turning obstacles into opportunities, fostering a positive attitude, surrounding yourself with positive influences, visualizing success, taking decisive actions, maintaining faith in your abilities, and practicing gratitude and prayer.
What is the difference between a positive and non-positive displacement pump?
Non-positive displacement has slippage inside the pump and it is a continous, variable flow. But positive displacement has no slippage inside the pump, and it is a constant flow.
Is there a general rule that you must always follow when multiplying or dividing an inequality by a negative value?
positive and positive are positive positive and negative are negative negative and negative is positive
What causes the inside of neuron becomes positive?
Outside a neuron, there are mostly sodium ions but some potassium ions. Inside the neuron, there are only potassium ions. Since both sodium and potassium are positive ions, and they are in a higher concentration outside the cell, that makes the outside have a more positive charge than the inside. But for all intents and purposes, the outside is positive, and the inside is negative. When the sodium ions (Na+) rush into the cell during depolarization, it causes the concentration of positive ions inside the cell to go WAY up, making the inside more positive than the outside. This means that the outside is now negative and the inside now positive.
What is the rule for multiplying and dividing with the same sign?
The answer is positive.
What is the rule in dividing integers?
The rule in dividing integers is to divide the absolute values. Two positive integers or two negative integers equals positive product. If one integer is positive and the other is negative, the product is negative.
What is the rule in multiplying integers with the same sign?
When you multiply two integers of the same sign, the answer is always positive. A positive times a positive is positive and a negative times a negative is positive.
Rule for multiplying integers?
Positive x negative = negative (Negative x positive = negative) Positive x positive = positive Negative x negative = positive So if the signs are the same the answer is positive and if they are different it is negative.
Why does a negative times a negative equals a positive?
It is a rule in math!
