Answer:

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

If im wrong so be it >:)

Answer:

b

Explanation:

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.

Onsidering that gluconeogenesis requires a net input of 4 atp equivalents compared to glycolysis, why would a cell utilize this
Pani-rosa [81]

The process by which organisms create sugars (specifically glucose) from non-carbohydrate precursors is known as gluconeogenesis.

  • The only energy source used by the brain, testes, erythrocytes, and renal medulla is glucose, with the exception of ketone bodies during fasting. There are three highly exergonic stages in glycolysis. Hexokinase, phosphofructokinase, and pyruvate kinase are among the enzymes involved in these additional regulatory stages. In biological processes, both forward and backward reactions are possible.
  • Similar to glycolysis, but with the process going the other way, is gluconeogenesis. Fructose-1,6-bP, glucose-6-P, and pyruvate all undergo fairly spontaneous conversions in the process of gluconeogenesis, which is why these reactions are tightly controlled.
  • For the organism to function properly, energy conservation is crucial. Gluconeogenesis is suppressed when there is an abundance of energy available.

Therefore, gluconeogenesis conserve more energy.
