Answer:
they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes
Explanation:
G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.
Biological macromolecules are synthesized by dehydration
synthesis reactions and are broken down by hydrolysis
reactions.
<h3>What are Biological macromolecules?</h3>
These are formed from smaller compounds and are necessary
for proper life functions of cells. Examples of these
macromolecules include:
Dehydration synthesis involves the loss of water molecules in
the process while hydrolysis reaction involves the addition of
water molecules.
