Which is a correct explanation of an aspect within G protein signaling pathway? ATP powers the G protein to cause it to move and activate an enzyme O GTP activates the G protein causing it to move to activate the next protein O The receptor is active when bound to GTP GTP causes the G protein to activate and bind to the receptor

How could we promote rapid or slow signaling for medical purposes? So there are many examples of slow and rapid signaling via coupled receptors. For an example, salivary gland secretion is rapid signaling and cell growth is slow signaling. These pathways could be twisted and used to resolve medical issues in a more natural and less damaging way. Are there any experiments that have or could be done to test out promoting rapid signaling to speed up slow processes such as cell growth in a severe wound? What experiments have or could be done to test out slowing down signaling that is fast like cells responding to their environment negatively (over-active allergies)? Thank you.

what happens to a water souble hormone after it binds to a receptor on the target cell? select all that apply A. the hormone unbinds the receptor or pops back off B. the hormone is broken down by an enzyme C. the hormone is transported into the cell where it is destroyed by enzymes d. the hormones is transported into the cell where it promotes transcription.
