Receptors are needed for both Short and Long range cell signaling.
<h3>What are receptors?</h3>
In the cell, there are some special proteins who play the role of receiving external signals. These are what we call receptors.
These receptors could function for both long and short range cell signaling. Hence, Receptors are needed for both Short and Long range cell signaling.

- ATP supplies energy for cellular activities by releasing one of the phosphate group in its molecule
- Cellular activities in living organisms make use of ATP as source of energy
<h3>What is ATP?</h3>
ATP stands for Adenosine triphosphate and it is an energy carrier molecule in living cells of an organism.
The ATP molecule is made up of three components namely;
- Nitrogenous base
- 3 Phosphate groups
- Five carbon sugar
The ATP molecule gains one phosphate group when it stores energy and loses one when it releases energy.

The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.
