1 of 16 Data from an experiment is shown in the figure below. In the experiment, murine cells were treated with a specific a ligand that activates receptor R. In some cases, the cells were exposed to one of two drugs (X or Y) as well as the ligand or were left untreated (UT). After 30 minutes of treatment, the cells were lysed with a detergent-based buffer to release the soluble membrane, cyosolic and nuclear proteins. Samples from each cell extract were run (in duplicate) by SDS-PAGE (SDS-polyacrylamide gel electrophoresis) in order to separate the proteins by molecular mass (size). The separated proteins were then transferred to a nitrocellulose membrane which was then probed with different antibodies in a western blotting procedure to detect specific phosphorylated proteins or total proteins. If present in the cell extract, these proteins appear as a dark band in the relevant western blot image within the figure. Drug X Drug Y UT Ligand Ligand Ligand Western blotting antibodies…

HC CH reaction with HC CH lysosome CH CH HC CH3 HC CH3 HC CH HC. CH CH3 CH3 ОН OH inside the cell, propranolol sometimes encounters lysosomes, which alter its NH group as shown above (right). reacting with the lysosomes, propranolol becomes trapped inside the cell and can cause psoriasis or other inflammatory side effects. Use IMFS to explain why the altered propranolol gets trapped. T
a. What is the function of bactoprenol in peptidoglycan synthesis? b. During peptidoglycan synthesis, removal of a phosphate group from bactoprenol pyrophosphate is inhibited. What is the immediate outcome? What does this mean for cell wall synthesis? Which antibiotic works via this mechanism? c. Bacterium Y is photosynthetic. You want to decrease the ability of Bacterium Y to produce glucose through photosynthesis. Explain how you could manipulate the light reactions of photosynthesis to decrease glucose production during the dark reactions in Bacterium Y. Include the name of the pathway that makes glucose during the dark reactions, which/how molecules from the light reactions are used in this pathway, and what specific steps of this pathway would be affected by your manipulations.
Part A How can an understanding of enzymes and biological receptors guide medicinal chemists? Match the words in the left column to the appropriate blanks in the sentences on the right. Submit an increase will not less more a decrease will Request Answer Reset Help 1. A better understanding of biological processes such as the behavior of enzymes and biological receptors be beneficial for medicinal chemists. Chemists can design drug molecules effectively to resemble biological molecules and their actions. The new medicines and materials can be developed quickly and safely, leading to in both energy usage and cost.

Amoeboid cells that migrate through our tissues, such as the class of white blood cells known as neutrophils, often do so in a directed manner, triggered, for instance, by chemical signals released by pathogens such as bacteria. Directed migration in response to a chemical stimulus is known as chemotaxis. Part of an efficient chemotactic response is the ability of cells to polarize. As is the case with our structurally-polar polymers like F-actin or microtubules, polarization here refers to an asymmetry in the cells, rather than an electrical charge. In this case, it involves one part of the cell becoming the “front” (or leading edge) and another the rear. In a well-polarized, migrating cell, it’s been observed that an active form of Rac (which, in turn, can activate ARP 2/3) is concentrated towards the front of the cell, whereas an active form of Rho (which, in turn, can activate formin, inhibit ADP, and activate myosin II) is found toward the rear of the cell. Based on your…

Which one of the following is NOT true about ECM? O ECM is composed of an interlocking mesh of fibrous proteins and glycosaminoglycans. O ECM supports cell-to-cell communication and stem cell differentiation. O Proteoglycan complex has a unique bottle brush-like structure. It is positively (+) charged. It is composed glycosaminoglycans and carbohydrates that are attached to the proteins. O ECM is a collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding cells.
