The theory that a drug attaches itself to specialized cells in the body because of its size, shape, electrical charge, and chemical properties is called receptor site theory.
c.
In the nucleus, the part on the cell that contains all the genome
Answer:
The sodium-potassium pump contributes to the resting membrane potential.
Explanation:
This is the stage in which the neuron is not depolarize. 3Na+ are pumped outside through the sodium channels, while K+ channels are open for2 K+ to enter the cells.After some time the Na+ channels closed up. However some K+ channels still leaks , so that K+ still escape out of the cells to the external environment ,which contains more of Na+. Therefore at this stage there are more Na+ outside the neuron compare to the inside the neuron. Therefore the inside of the neuron is negative , because more K+ are leaving the cells, leaving negatively charged anions inside, and the outside is positive due to more Na+ are outside, and because the K+ leaking outwards.
The regulation of the Na+ and K+ ions movements is regulated by sodium potassium pumps along the membrane of the neuron. if the potential at this stage is measured, it has a value of -70mv, and it is called membrane potential.
Lipids with a double bond are unsaturated fats, which are healthier than saturated. One example of this would be olive oil (a healthier fat than say, butter)
B. a new material is created
