When a signaling molecule binds to the GPCR, the G protein alpha subunit exchanges GDP for GTP. The alpha subunit dissociates from the beta and gamma subunits and interacts with other molecules, ultimately triggering a cellular response. ... GTP is hydrolyzed to GDP, and the signaling molecule comes off of the receptor.
Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.
Answer:
<em><u>Individual organisms live together in an ecosystem and depend on one another. ... One category of interactions describes the different ways organisms obtain their food and energy. Some organisms can make their own food, and other organisms have to get their food by eating other organisms</u></em>
