Question

Describe the roles of the components of the signal transduction pathway: signals receptors, transduction, and the cellular responses that produce the intended results. . Differentiate among paracrine, autocrine, and hormonal signals.| Differentiate among three categories of membrane receptors: ion channels, protein kinases, and G protein-linked receptors. . Explain how intracellular receptors differ from membrane receptors in terms of mechanism of action and downstream results. Describe the roles of receptor antagonists (e.g., caffeine) on the actions of signaling molecules . If a drop of red ink is placed in one end of a shallow pan filled with water, and a drop of blue ink is placed in the other end, how will the ink be distributed at true at equilibrium? . If you forget to water a potted plant, its leaves wilt. What is a likely reason for

Explanation / Answer

Role of signals: carry information from outside to cell. Receptors: receive the signals and are specific for each cell type in accordance with function. Transduction: amplifies the signal many many times for an enhanced effect. Cellular responses: respond to signal and activates genes which produce specific proteins as per the information provided by signal. This is carried out by translation.
