Answer:
CO₂, also known as carbon dioxide
Explanation:
In the alveoli, oxygen enters the bloodstream, and carbon dioxide exits, the latter to be exhaled from the lungs.
A drug that interacts directly with receptor sites to cause the same activity that a natural chemical would cause at that site is the instructors best response.
Explanation:
Receptors are Macromolecules which involved in chemical signalling within cells. It is possible that receptors are located in the cell surface membrane. Cellular biochemical process is regulated by Activated receptor. The drugs are capable to affect to receptor who is related to the drug’s affinity and also intrinsic efficacy.
The affinity and activity of drug is related to its chemical structure. its effect is decided by the time duration where complex persistence of drug-receptor.
