True or False - answerTrue Enzymes used for Glycogen synthesis - answerPhosphoglucomutase, UDPGlc pyrophosphorylase, and Glycogen synthase Glycogen synthesis - UDPGlc pyrophosphorylase: - answerGlucose 1-P + UTP → UDPGlc Glycogen synthesis - Phosphoglucomutase - answerGlucose 6-P is i...

G-Protien coupled receptors and how they interact with drugs - G-protein coupled receptors (GPCR) interact with drugs through 7 regions of proteins that span and innervate the cell membrane and trap the molecule into the receptor site like an interwoven basket (Insel & Sriram, 2018). Drugs can then enter this space and interact with the GRCP. A specific interaction and binding with a site on one or more of the regions of proteins within the GPCR, and drugs bound with the GRCP can stimulate t...

Signal transduction pathway - Organization and function of cell signaling process Ligand-receptor binding - Experiment to measure interaction between ligand and receptor GPCR signaling - Signal transduction through G-protein coupled receptors RTK signaling - Signal transduction through receptor tyrosine kinases Signal transduction experiments - Interpretation of data from experiments on cell signaling Kd (Dissociation constant) - Quantitative measure of receptor-ligand affinity

Cell membrane Correct Answer Phosphatidylcholine and sphingomyelin on EC side Phosphatidylethanolamine and phosphatidylserine on inside Increase in cholesterol => decrease in fluidity/permeability In some cells, covered by carb-rich glycocalyx Receptor-mediated endocytosis => both receptor and ligand get ingested by clathrin-coated vesicle Disorders of transport Correct Answer CF: defect in CTFR => salty sweat and thick mucus Cystinuria: inability to reabsorb cys in kidneys =&gt...

What purpose does glycogen degradation and synthesis serve in animals? correct answers Liver glycogen is short-term energy which provides a way to store and release glucose in response to blood glucose levels. Which of the following is correct concerning the regulation of glycogen metabolism by hormones? -Glycogen phosphorylase is active when phosphorylated, which occurs in response to insulin. -Glucagon activates PKA, which inactivates glycogen synthase -Epi has the same effect as insul...

UNC Biol 205 Exam 2 Questions With Verified Answers when cells respond to an extracellular signal, they most often convert the information carried by this molecule from one form to another. What is this process called? - answersignal transduction When does signal transduction begin? - answerwhen the receptor on a target cell recieves and incoming extracellular signal and then produces intracellular signaling molecules that alter cell behavior extracellular signal molecules, released loca...
