Detailed explanation-1: -Hormonal agents may be broken down into two primary forms, slow acting (steroid and thyroid) and fast acting (peptides and catecholamines). The slow acting hormones must first penetrate the cell membrane and enter the nucleus of the cell.
Detailed explanation-2: -Thyroid hormone has the longest half-life, approximated to be days. Thyroxine, among many other things, regulates your metabolic activity, mood, and temperature. They are tyrosine-based hormone levels that are mainly responsible for metabolism regulation.
Detailed explanation-3: -Thus, whereas neurotransmitters’ effects are localized, the effects of hormones are widespread. Also, hormones are slower to take effect, and tend to be longer lasting.
Detailed explanation-4: -Hormones bring about their characteristic effects on target cells by modifying cellular activity. Protein hormones react with receptors on the surface of the cell, and the sequence of events that results in hormone action is relatively rapid.
