Answer:
In communication between cells, the SIGNALING CELL produces the signaling molecule, also known as the LIGAND; the RESPONDING CELL produces the RECEPTOR, to which the signaling molecule binds,
Explanation:
The term cell signaling refers to the mechanisms by which cells communicate with one another and mainly includes cells, ligands, and receptors. To send a signal, the signaling cell synthesizes and release signaling molecules called ligands. The ligands are to be transported if the responding cells are distantly located.
As the signal molecule reaches the responding cell, it binds to the receptors present on the surface of the responding cells. This process is called reception as the responding cell receives the signals. Some cells produce cytosolic or nuclear receptors for their signaling molecules.
Explanation:
<u><em>Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disorder have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.</em></u>
<u><em></em></u>
Signs and symptoms of sickle cell disease usually begin in early childhood. Characteristic features of this disorder include a low number of red blood cells (anemia), repeated infections, and periodic episodes of pain. The severity of symptoms varies from person to person. Some people have mild symptoms, while others are frequently hospitalized for more serious complications.
The signs and symptoms of sickle cell disease are caused by the sickling of red blood cells. When red blood cells sickle, they break down prematurely, which can lead to anemia. Anemia can cause shortness of breath, fatigue, and delayed growth and development in children.

Binding domain is a protein domain which binds to a specific atom or molecule, such as calcium or DNA. ... Upon binding, proteins may undergo a conformational change. Binding domains are essential for the function of many proteins.
