- Sulfamethoxazole is a type of sulfonamide antibiotic. Its absorbance ranges from 250-300 nm in a UV spectrophotometer, which tells that it is in the UV region. What characteristic/s of sulfamethoxazole is responsible for the absorbance in the UV region? Please answer in detail and clearly. Thank you!arrow_forwardThe nerve gas sarin acts as a poison by covalently bonding to a hydroxyl group in the active site of the enzyme acetylcholinesterase. This binding results in a higher-than-normal amount of acetylcholine at a nerve synapse, resulting in muscle spasms. From this description, would you expect sarin to be a competitive, noncompetitive, or irreversible inhibitor? noncompetitive inhibitor irreversible inhibitor competitive inhibitorarrow_forward1)The concept of saturation is defined as? a) The ability of a receptor to bind only one type or a limited number of structurally related types of chemical messengers. b) The degree to which receptors are occupied by messengers. c) A decrease in the total number of target-cell receptors for a given messenger d) The increased responsiveness of a target cell to a given messenger 2. Phosphodiesterase activity produces one of the following actions a) Breakdown cAMP b) Increases cAMP c) Increases PKC activity d) Increases cytosolic IP3 levels 3. Phospholipase C leads to one of the following? a) Increase in cAMP b) Breakdown of cAMP c) Increase in cytosolic levels of IP3 and DAG d) A decrease in cytosolic Ca++ concentrationarrow_forward
- What are the visible parts here in Hydrilla?arrow_forwardOne such neurotoxin, Sarin (chemical name: propan-2-yl methylphosphonofluoridate) is considered a weapon of mass destruction by the United Nations by virtue of its ability to kill with great efficiency in very low concentrations. a. Where does Sarin have its effect (what is/are its target) and describe the mechanism of action of Sarin (how does it kill)? b. Describe the physical symptoms observed in those stricken with Sarin that are consistent with this mechanism of action. Include flaccid/tonic paralysis, as applicable.arrow_forwardIn the figures below, observe the biosynthesis of scopolamine and its intermediates. THE scopolamine is formed by the fusion of two biosynthetic pathways. One derived from L-ornithine and the other from L-phenylalanine. In the bold rectangles are the respective key enzymes that catalyze each of the biosynthesis steps. Scopolamine is a competitive, non-selective muscarinic receptor antagonist drug acetylcholine receptor antagonist (mACHR) giving rise to important pharmacological effects, such as by example antispasmodic action in the gastrointestinal tract. Answer: 13) Briefly explain, in text, the reactions necessary for the biosynthesis of scopolamine from the litorine.arrow_forward
