, the Northern Hemisphere has summer. At the same time, the south end of Earth's axis is tilted away from the sun so other parts of the world is cold. as the earth revolves on its axis, we will soon experience winter as well. places like Antartica will always be cold , just because how its on the earth. its far far far aways from the sun. thats why it stays cold there.
Explanation:
The information from a signal molecule present outside the cell elicits intercellular response when the G protein coupled receptors interact with the wide variety of molecules on the outer surface of the cells.
G Proteins are the specialized proteins having the ability to bind GTP and GDP and is of three units called Alpha, Beta and Gamma subunits which together formed G proteins.
When G protein is activated it will bind GTP and each receptor binds in lock and key method and binding result into conformational change which will trigger a complex chain of events influencing different cell function.
Features exhibited by Signal Transduction System are:
1. Specificity- Signal molecules fits binding site on its complementary receptor. Other signal do not fit
2. Amplification- When enzymes activates enzymes, the number of affected molecules increases.
3. Desensitization- Receptor activation triggers a feedback circuit that shuts off the receptor or removes it from the cell surface.
4. Integration - When two signals have opposite effects on a metabolic characteristics outcome results from the integrated input from both the receptor.
