Question

Typical responses to ______ messengers required a long time to develop because they necessitate transcription of mRNA and translation of that mRNA into a functional protein.

Select one:

a) lipophobic
b) amine
c) peptide
d) steroid
e) protein

Answer 1

Answer

d) steroid

Explanation

• Typical response to lipophilic messengers took long time to develop, because they are lipid soluble.
• option a) and option b) are wrong because, they are lipophobic
• option c) and e) are wrong because, some proteins have hydrophilic and hydrophobic end.Individual sequence of protein is connected by peptide bond,
• option d) steroid is a lipophilic hormone, hence they can pass through nuclear membrane and cell membrane, and receptors are located inside the cell mostly.
• lipophilic hormones necessitate transcription of mRNA and translation of that mRNA into functional protein.
