GENERAL HISTOLOGY

Detailed explanation-1: -Answer and Explanation: The type of protein that detects a signal molecule and induces a signal Cascade in response is a cellular receptor.

Detailed explanation-2: -A receptor is a protein that detects a signal molecule and performs an action in response.

Detailed explanation-3: -How Do Cells Recognize Signals? Cells have proteins called receptors that bind to signaling molecules and initiate a physiological response. Different receptors are specific for different molecules.

Detailed explanation-4: -Signaling molecules bind to the extracellular domain of two nearby tyrosine kinase receptors, which then dimerize. Phosphates are then added to tyrosine residues on the intracellular domain of the receptors and can then transmit the signal to the next messenger within the cytoplasm.

Detailed explanation-5: -Receptors are protein molecules inside the target cell or on its surface that receive a chemical signal. Chemical signals are released by signaling cells in the form of small, usually volatile or soluble molecules called ligands.
