Cell to Cell Communication Two or multiple cells who are in a close radius have the capability to communicate with each other through the plasma membrane. Cells send signals through steps of signal transduction pathway. Cells communicate through chemical messages long distance and in a short radius.
Different Types of Signaling
In long distance and short distance signaling there are many different types of signaling used for communication between cells. The local communication is done through paracrine signaling or synaptic signaling; long distance signaling is called hormonal signaling. Within these two ways of communication, specific chemicals go to their assigned cell and have a given response.

The nerve cell knows when to release a neurotransmitter after an electrical signal is triggered. Once the electrical signal is triggered the nerve cell will secrete a chemical, the neurotransmitter, which will diffuse across the synapse. The synapse is a compact space between the target cell and the nerve cell.
Hormonal Signaling
Endocrine cells secrete hormones into the blood vessel, which then send them to target cells. For any cell signaling and response to happen, a specific cell must send a molecule to a target cell.
Stages of Cell Signaling
Cell signaling is split into three different stages reception, transduction, and response. Reception occurs in at the membrane of the cell, transduction occurs during the signal transduction pathway, and response is triggered by the molecules.
Reception
Reception is the beginning step of cell signaling, during this step, the signal cell will bind to a protein that is on the plasma membrane to begin the next step of cell signaling.
Transduction
When the signal cell binds to the protein, it changes the receptor protein; for example, it might change in shape. The signal of the cell has a molecule that that causes a specific …show more content…
This helps keep the cells balanced, growing, and reproducing.
Ion Channel Receptors
This receptor acts as a gate after the receptor has changed shape, this gate opens or closes as Sodium and Calcium block or allow passage through the gate.
Cell Cycle
The cell cycle is continuous repetition of cells dividing and multiplying.
Resulting in Identical Daughter Cells
When a cell divides, it grows and the DNA copies to make two identical cells.
Organization of DNA
Before the cells divides, the cell copies the DNA and the two sets of DNA are separated into chromosomes. The chromosomes are then split up at the two poles are of the cell to be able to divide.
Distributing Chromosomes
When the DNA copies, it condenses into chromosomes, two chromosomes are put together to make sister chromatids. The narrow part of the chromatids are the centromeres, this is where they are most closely attached.
Phases of the Cell Cycle
Mitosis
This is the shortest part of the cell cycle.
Interphase
This takes up 90% of the cell cycle, this is when the cell grows bigger and gets “fat and sassy” and copies the
