B) The membrane-embedded enzyme uses GTP as a secondary messenger to initiate gene expression.
Explanation:
Due to the fact G Protein Coupled Receptors (GPCRs) perceive many extracellular signals and transduce them to heterotrimeric G proteins, which further transduce these signals intracellular to appropriate downstream effectors and thereby play an important role in various signaling pathways
PCRs are a large family of cell surface receptors that respond to a variety of external signals. Binding of a signaling molecule to a GPCR results in G protein activation, which in turn triggers the production of any number of second messengers.
The most plausible hypothesis to explain why species richness is higher in tropical than in temperate regions is that B) tropical regions have more available water and higher levels of solar radiation.
Lipase is a type of enzyme known as a hydrolase and is responsible for catalysing the hydrolysis of triglycerides (the substrate) into fatty acids and glycerol
