Question

membrane bound receptors and hormones produce second messengers like...........?
options:
1.Renin
2.IP3
3.ANF
4.GHRF​

Answer 1

The correct answer is renin

Answer 2

The answer is (2) IP3. Second messenger systems is known to participate in hormone actions are cyclic AMP(cAMP), cyclic GMP (cGMP), Ca++/calmodulin, inositoltrisphosphate (IP3), and diacylglycerol (DAG). 

The hormone and receptor form a complex that activates a chain of molecular events within a cell. The hormone thus acts as a first messenger that roots the beginning of a second messenger system in the cytoplasm. inositoltrisphosphate (IP3) is a second messenger.
