Hormones which interact with the membrane-bound receptors normally do not enter the target cell but generate second messengers. These second messengers are referred as
- ACalcium ion and inositol 3-phosphate
- BInositol 3-phosphate and cAMP
- CcAMP and calcium ion
- Correct answerDAll of the above
Solution
Second messengers are intracellular signalling molecules released by the cell in response to exposure to extracellular signalling molecules: the first messengers.
Examples of second messenger molecules include cyclic AMP, cyclic GMP, inositol trisphosphate, diacylglycerol and calcium.
Examples of second messenger molecules include cyclic AMP, cyclic GMP, inositol trisphosphate, diacylglycerol and calcium.
Hence, the correct answer is option: 'D'.
