The current scientific definition of hormones states that they are:
1. Nutrient chemicals produced by endocrine glands in large amounts and transported through blood to nearby tissues
2. Non-nutrient chemicals which act as intercellular messengers and are produced in trace amounts
3. Protein molecules synthesized only by organized endocrine glands and secreted through ducts
4. Lipid-soluble substances that provide energy to cells and are produced in high concentrations

Consider the two statements:
Assertion (A): Although hormones are circulated by blood they act only on their target tissues.
Reason (R): Hormones produce their effects on target tissues by binding to specific proteins called hormone receptors located in the target tissues only.
