Obtain molecules they need.
Answer:
It exhibits specificity for a particular type of molecule
.
Explanation:
Carrier proteins are a kind of transmembrane protein which helps in the transport of molecules across the cell membrane. Carrier proteins specifically binds to a particular and specific type of molecules and helps in their transportation.
If they transport the molecules without the expenditure of energy then it is considered as facilitating diffusion and when they use ATP for transport it is called active transport.
Inactive transport, molecules are moved against their concentration gradient and in facilitated diffusion, molecules are moved along their concentration gradient.
The answer is ecological pyramid (also called trophic pyramid or energy pyramid).
Explanation:
The equation that shows the equilibrium reaction of carbon dioxide in the blood is the following one:
<h3>
CO₂ + H₂O ↔ H₂CO₃ ↔ H⁺ + HCO₃⁻</h3><h3 />
This equation describes the bicarbonate buffer system which regulates the pH of the blood.
- During hypoventilation, the CO₂ produced by the cells through metabolism is not released fast enough, so CO₂ levels in the blood increase. In this situation, the equation shifts towards the right, and an excess of protons is produced, therefore decreasing the pH and causing acidosis.
- During hyperventilation the breathing is very rapid and CO₂ is exhaled from the body at a very fast rate. In this situation, the CO₂ levels in the blood decrease, the equation shifts towads the left and the concentration of H+ thus decreases, causing alkalosis.
