Describe endocrine, paracrine, and autocrine signaling. correct answers Endocrine: An endocrine cell releases a hormone into the blood stream to target a receptor on the target cell. Paracrine: A signaling cell releases a local mediator to target cells (neighboring cells). Autocrine: A cell releases a chemical signal to target itself. How does a hormone that is released generally throughout the body end up having different effects on (or no effects on) different cells? correct answers H...

TSH, LH, FSH are from the same hormone family. They are similar in that they - all contain 2 protein chains and the alpha-chain is each identical Hormone binding/carrier proteins: - help solubilize hormones in blood, protect hormones from being degraded by the liver, reduce concentration of free hormone able to bind receptors Synthesis of norepinephrine from tyrosine - requires enzymatic conversions Phospholipase A2 would be activated - during the synthesis of prostaglandin Insulin affects...

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...

Synthesized in the dark and is broken down by rubisco activase or light. A-form DNA - Answer -Condensed form of DNA. Deeper major groove and shallower minor groove. ACC (acetyl-CoA carboxylase) Regulation - Answer -Inhibited by PKA in glucagon chain and activated by pjhosphatase in INSR chain. Additional Cost of FAS in Eukaryotes - Answer -Acetyl-CoA for li...

The second messenger in the signaling cascade initiated by glucagon is: correct answer: cAMP Explanation: The second messenger for glucagon is cAMP. Review Module 2 GPCR signaling cascades When insulin is bound to its receptor an autophosphorylation event occurs and the IRS binds these phosphorylated sites through interactions with the: correct answer: SH2 domain Explanation: SH2 domains bind with phosphorylation sites and allow for docking of the IRS with the insulin receptor. Insulin...

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...
