observe the diagram carefully and explain what it indicating and what it is showing?
Answers
Answer:
a) It is an active form of transport
b) In this process:
The carrier protein faces towards the extracellular face
The substrate particles get attached to the carrier molecule
The carrier molecule translocates using chemical energy
Releases the substrate molecules into the cytoplasm of the cell.
After the release the carrier protein moves back to the cell surface.
Explanation:
This diagram shows a double circulation system.
In our body, two types of blood circulation run simultaneously. A.Pulmonary circulation and B.Systemic circulation. These together named as double circulation. In double circulation, blood flows twice through the heart.
Pulmonary circulation:- The circulation of blood between the heart and lungs. Due to this circulation deoxygenated blood or carbon dioxide-rich blood from the heart is carried to lungs where it removes carbon dioxide and receives oxygen. The oxygenated blood from the lungs is then carried back to the heart.
Systemic circulation:-This involves the circulation of blood between the heart and the body. The oxygenated blood from the heart is carried to all parts and the deoxygenated blood from the body parts is carried back to the heart.
because the blood flows from the heart twice and two separate circulations are involved it is known as a double circulation system.
