  • A IP3 and DG ✔ ✖
  • B cAMP ✔ ✖
  • C G-protein ✔ ✖
  • D PIP2 ✔ ✖
Correct Answer: Option A

Explanation

IP3 and DG (diacylglycerol) act as second messengers to amplify signals initiated by hormones or neurotransmitters binding to cell surface receptors. IP3 binds to receptors on the endoplasmic reticulum, leading to the release of calcium ions into the cytoplasm, which in turn activates various enzymes and other proteins. DG, on the other hand, activates protein kinase C, which phosphorylates target proteins and amplifies the signal. This amplification of signals is crucial for the body to achieve appropriate physiological responses.
