3 of 16 Which statement about the IP3 DAG pathway is false? O Diacylglycerol can act as a second messenger. Inositol trisphosphate can act as a second messenger. O Protein kinase C can phosphorylate a wide variety of proteins. O Inositol trisphosphate remains bound to the membrane after phospholipase C catalyzes its formation. Inositol trisphosphate can open ion channels in the membraņes of smooth endoplasmic reticulum, releasing calcium into the cytoplasm.

Different types of signaling between cells Briefly describe the 6 different signal paths
The basic elements or molecules of cell signaling I. second messengers - substances that enhances or inhibits activities of other proteins II. effectors - are usually enzymes that catalyzes formation of the second messenger III. receptors - cell membrane transmembrane proteins that interacts with ligands outside the cell IV. first messengers - usually are ligands outside the cell and interacts with transmembrane protein receptors I, III, IV only II, III, IV only I, II, III, IV I, II, III only
Put the steps of the process of signal transduction in the order they occur (hint - try to decide which signaling pathway this is before working on the order): 1. A conformational change in the signal-receptor complex activates an enzyme. 2. Protein kinases are activated. 3. A signal molecule binds to a receptor. 4. Target proteins are phosphorylated. 5. Second messenger molecules are released. O 1, 2, 3, 4, 5 O 3, 1, 2, 4, 5 O 1, 2, 5, 3, 4 O 3, 1, 5, 2, 4 I
nicotine from cigarette smoke acts as a lignad and associated with specific proteins on the surface of cells in the brain, causing felings of pleasure nad well being. What is the appropriate event in the cellular response to nicotine Rapid elimination of nicotine from the body is an example of: 1. receptor binding 2. signal termination 3. recepto activation 4. signal transduction 5. cellular response
During signal transduction (a) the cell converts an extracellular signal into an intracellular signal that leads to a change in some cell process (b) a signaling molecule directly activates or represses several genes (c) each enzyme catalyzes production of one molecule of product (d) enzymes in the signal cascade remain active until the last component of the pathway alters a cellular process (e) the signal is terminated by cyclic AMP
Calcium ions (a) can act as second messengers (b) split calmodulin (c) are kept at higher concentration in the cytosol than in the extracellular fluid (d) are produced in the ER by protein kinases and protein phosphatases (e) typically terminate signaling cascades
