Examples of second messenger molecules include Cyclic AMP, Cyclic GMP, Inositol Triphosphate, Diacylglycerol, and Calcium. The cell releases second messenger molecules in response to exposure to extracellular signaling molecules-the first messengers. First messengers are extracellular substances that include peptide hormones such as epinephrine, growth factors, neurotransmitters such as serotonin and steroid hormones.
