MECHANISM & ACTION OF HORMONE

The binding of hormone to its receptor leads to

• formation of hormone receptor complex

• biochemical changes in the target tissue

• affect target tissue metabolism

• All of these

Besides cAMP, which of the following molecules acts as a secondary messengers?

• Ca2+

• ATP

• cDNA

• CGTP

How do peptide hormones exert their effects on target cells?

• By binding to intracellular receptors

• By activating G-protein coupled receptors

• By acting as second messengers

• By increasing gene transcription

incorrect match with respect to hormone and its chemical nature is

• Cortisol-steroidal

• Thyroxine-iodothyronine

• Glucagon-steroidal

• Thyrocalcitonin-proteinaeous

Which of the followings is the incorrect answer

• Hormones bind to specific protein located in the target tissue only

• Receptors of hormone only can be found on the cell membrane

• Each receptor is specific to one hormone only

• Nuclear receptor is intracellular receptor

Which of the following pairs of hormone are the example of those hormone bind to the entracellular receptor
