Master Hormones: Types and Mechanisms fast ⚡ – clear explanations, OCR-aligned.
You’ll cover
• The key differences between steroid hormones and non-steroid hormones.
• How hormones act as first messengers to transmit signals to target cells.
• How second messengers transmit signals inside target cells.
• The enzyme cascade triggered by non-steroid hormone signalling.
• How steroid hormones bind intracellular receptors and regulate gene expression.
What’s included
• Diagram showing how a steroid hormone enters a target cell and regulates gene expression.
• Diagram illustrating non-steroid hormone signalling via membrane receptors and second messengers.
• Step-by-step explanation of adrenaline signalling via cAMP and G-protein activation.
• Diagram showing the mechanism of adrenaline action in a target cell.
• Example exam-style model answer explaining adrenaline’s signalling pathway.
• Diagram illustrating the intracellular mechanism of steroid hormone action.
