SHORT ANSWER (Enter your answer in between all(prenominal) interrogation (2-8 lines should sufficedepending on the question) 1. Suppose a dose had the akin size of it and shape as a substrate and come across into an enzymes consummationive website. Explain how the drug could make a motion the enzymatic reply rate. What is the term for this type of sum of money or reaction? (2 marks) A drug of same size and shape, as that of a substrate, which fits into the diligent site of an enzyme will act as a agonistical inhibitor and the reaction is termed as rivalrous inhibition. The drug will compete with the substrate mite for the active site of an enzyme, thus, it will decrease the rate of substrate-enzyme reaction by ski screen to the active site of enzyme. The rate of competitive inhibition reaction is directly proportional to the concentration of inhibitor present. 2. Glucose travelings in the plasma or liquid jump of your inventory only cholesterol (tr iglycerides) travel bound to protein flattops in the blood. establish on their respective chemical properties, explain the reason for this difference. (2 marks) Cholesterol is an amphipathic molecule, since it has frozen and non cold regions.

take down though the cholesterol has polar group (OH) it dissolves fats than in sedimentary solutions and since the blood is aqueous in nature cholesterol travels in blood by binding to the lipoproteins. Whereas, glucose has five negatively superaerated OH groups on it that attracts positively charged hydrogen atoms of water molecule making glucose water soluble. Therefore , glucose roll in the hay travel in blood b! y dissolving in blood plasma it does not require any carrier protein to travel through the blood. 3. nitrile is a poison that very specifically blocks the transport of electrons in the electron transport chain. Based on the purpose of this part of cellular respiration, why would you say that cyanide is so mortal(a)? (1 mark) Cyanide binds to the cytochrome c oxidase enzyme inhibiting the transfer of electrons from ordinal complex to...If you motivation to get a full essay, revisal it on our website: OrderCustomPaper.com
