Detailed explanation-1: -The hormone feedback mechanism is the mechanism that keeps the hormone balance. Increased or decreased hormone concentrations can occasionally stimulate and promote hormone release or inhibit hormone secretion. It’s known as feedback.
Detailed explanation-2: -The hormones bind to the target receptor that activates the enzymatic activity of the cell to bring about biochemical changes. Transcription of DNA is initiated by the hormone-receptor complex. The mRNA is translated into protein. This protein causes biochemical changes inside the cell.
Detailed explanation-3: -The endocrine system is a tightly regulated system that keeps the hormones and their effects at just the right level. One way this is achieved is through ‘feedback loops’. The release of hormones is regulated by other hormones, proteins or neuronal signals. The released hormone then has its effect on other organs.
Detailed explanation-4: -Growth hormone levels are increased by sleep, stress, exercise and low glucose levels in the blood. They also increase around the time of puberty.
