The subcellular structure that degrades proteins is called the: A. Tight junction B. Mitochondria C. Lysosome D. Plasma membrane E. Ribosome ANS: C 2. An experiment is done to measure the uptake of an amino acid into a cell. The following data are obtained: If Na+ is removed from the extracellular bathing solution, or if a drug is added that...

G-Protien coupled receptors and how they interact with drugs Correct Answer 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 st...

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...

A G-protein coupled receptor (GPCR) is a seven-pass transmembrane domain receptor that aids in the signaling cascade essential for various pathways in the body. Although the receptor is situated such that it is predominantly contained within the cell membrane, small portions can be found exposed to the aqueous environments on either side. One such portion is the region that allows for ligand binding on the extracellular surface. Which of the following amino acids could be found within the ext...
