BIOSC-101 Lecture Notes - Lecture 16: Protein Kinase A, Cytosol, Signal Transduction
Document Summary
Clicker question:in signal reception, a single receptor is present, the signal receptor can be blocked by a small molecule, and the signal molecule can be either hydrophobic or hydrophilic. Once a cell receives a signal, something must happen to initiate the cell"s response. Lipid soluble molecules can be directly processed without any intermediate steps. Lipid insoluble signals must undergo signal transduction. Conversion of a signal from one for to another. The extracellular signal is converted into an intracellular signal, Clicker question: signal transduction and signal amplification occur and is usually amplified for lipid insoluble signals. Signal transduction begins at the plasma membrane. Two major types of signal transduction and amplification systems: G-protein coupled receptors initiate production of intracellular. Enzyme-linked receptors trigger protein activation in the cell (ex. In response to ligand binding, the receptor changes shape and activates its. The active g-protein interacts with another protein in the plasma membrane.
