It is the proteins, therefore, that give each type of membrane in the cell its ... Thus, the surface that the cell presents to the exterior is rich in carbohydrate
Ans.
The membrane proteins that pump sodium ions out of the cell from inside and potassium ions inside the cells are called as sodium-potassium pumps or sodium-potassium ATPases.
These proteins perform active transport by using energy from ATP hydrolysis and transport two potassium ions inside the cells, along with transport of three sodium ions outside the cells, against the concentration gradient.
Thus, the correct answer to complete the sentence is sodium.
<span>The low grade metamorphism of shale produces Slate which is denser than shale itself. Metamorphism is the change of minerals or geologic texture that happens due to heat which makes the chemical reaction happen leading it to decrystallization. Along with heat the other agents of metamorphism are fluid and pressure.</span>
Almost all living creatures on our planet depend on plants for food and oxygen, either directly or indirectly. So, if all the plants disappeared, eventually so would almost all the other life. Also, Earth would be hotter.
