Cell signalling refers to the mechanisms by which cells communicate with one another.
Cell signalling cascade, membrane transfer of molecules, etc.
There are generally three types of cell signaling: autocrine signaling (cell signals itself), paracrine signaling (cell signals nearby cells), and endocrine signaling (cell signals distant cells through hormones).
The boundary of the animal cell is the cell or plasma membrane. It is semi permeable, meaning it selectively transports ions or salts across the cell. They have transport proteins such as ion channels and receptor proteins than regulates transport and signalling events respectively.
Its the cell membrane (or plasma membrane), composed of phospholipid bilayer ,membrane proteins and cholesterol in eukaryotes. the regulation is largely by way of signalling molecules that interact with specefic receptors on the membrane (mostly proteins or glycoproteins). hope that helps Dr. David
Receptor proteins are specialized proteins that bind specific molecules, such as hormones or neurotransmitters, triggering a cellular response. Carrier proteins, on the other hand, are involved in transport processes, helping to move molecules across cellular membranes. While receptor proteins facilitate communication and signaling within the cell, carrier proteins play a more functional role in transporting molecules.
Cell signalling cascade, membrane transfer of molecules, etc.
disadvantage of in-band signalling
Yes - cell membranes have cholesterol scattered throughout them. Cholesterol plays an important role in maintaining the integrity of the cell membrane, and may also participate in cell signalling.
Primary messengers are hormones (extracellular molecules) that conduct the signalling events by not passing though the membrane but binding on the cell surface receptors. Secondary messengers are small molecules that may cross the membrane which actually conduct the downstream signalling events inside the cell (intracellular). cAMP, cGMP, calcium ions, inositol triphosphate are a few secondary messengers. cell proliferation, differentiation, migration, metabolism, cell death such as apoptosis events are all controlled by signalling pathways.
MESSAGES WOULD NOT BE SENT TO THE INSIDE OF THE CELL APEXXXXX
Cellular Signalling was created in 1989.

Separating cell contents from the outside environment. Separating cell components from cytoplasm. Cell recognition and signalling. Holding the components of some metabolic pathways in place. Regulating the transport of materials into or out of cells.
What causes ingestion of bacteria: Special bacterial recognition surface receptors on the cell's plasma membrane recognize the bacteria as bacteria and thus food. How these cause it to ingest the bacteria: These receptors cause signalling within the cell to occur. The signal is passed down through ATP-activated signalling proteins specialized for ingestion until it reaches the nucleus. In the nucleus, the signal is given to code for the "ingestion" action. It is coded onto mRNA which codes for cell-wide signalling. These signals reach all the organelles, which then work as one unit to engulf the bacteria with the plasma membrane.

autocrine signalling : the cell automatically signals it self through a chemical that it synthesizes and then respond to . example : insulin like growth factor secreted within muscle cell .
