∙ 15y agoThis is when the signal is sent directly to the organ, tissue, or a cell that needs it. An example of this is the neuron. A message is sent directly from or to brain

How many types of cell signaling?
There are mainly three types of cell signalling: Endocrine Exocrine and Autocrine signelling
Difference between receptor proteins and carrier proteins?
Receptor proteins are fond in cell membrane surfaces. They are not transport proteins, they conduct the signalling event that cause the cell proliferation, migration and cell death process such as apoptosis. Hormones activates such signalling cascades by binding on the hormone receptors of the cell.
What functions of the protein of the membrane?
Cell signalling cascade, membrane transfer of molecules, etc.
What happens if there is a deficiency of potassium in the human body?
if k not enough to our body mainly masage not transfor to our cell to cell by signalling pathway
Is a plasma membrane composed of Cholesterol molecules?
Yes - cholesterol is found in cell membranes. Cholesterol helps to stabilise the membrane. It is also sometimes involved in cell signalling.
What structures are used for direct Cell to Cell signalling?
Desmosomes are (inter-Cellular) bi-lipid layer conjoining structures that probably have a 'hollow center channel' that permits the transit of signal [signalling] molecules.

What are the disadvantages of outband signalling over inband signalling?
disadvantage of in-band signalling
Is there cholesterol in the membrane?
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.
What chemical messengers can pass through the plasma membrane and effect receptors in the cytoplasm?
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.
In biology what does the topic of cell signaling refer to?
Cell signalling in Biology is the communication system that coordinates cell actions and governs cellular activities. It is generally the thing most studied when determining diseases.
What would happen if a membrane protein were unable to bind to a signalling molecule?
MESSAGES WOULD NOT BE SENT TO THE INSIDE OF THE CELL APEXXXXX
When was Cellular Signalling created?
Cellular Signalling was created in 1989.
What has the author A Goldbeter written?
A. Goldbeter has written: 'Biochemical oscillations and cellular rhythms' -- subject(s): Biological rhythms, Cell physiology, Chaotic behavior in systems, Oscillating chemical reactions 'Cell to Cell Signalling'
