(a)
To draw: An activation energy diagram for reaction under catalyzed and uncatalyzed conditions. Compare the activation energy of reaction after using platinum and enzyme.
Introduction: Activation energy is the minimum amount of energy that is required for a reaction to occur. Whereas, transition state is a particular stage of the reaction at which free energy of reactants is high.
(b)
To describe: Two properties of catalase that make it a more suitable intracellular catalyst than platinum.
Introduction: Catalase is an enzyme which decomposes the hydrogen peroxide into hydrogen and oxygen. Platinum act as a catalyst and lowers the activation energy of the reaction.
(c)
To explain: Another way to accelerate the rate of hydrogen peroxide decomposition with its effect.
Introduction: Hydrogen peroxide is catalyzed by the enzyme catalase and converts it into water and oxygen molecule. Many ways can accelerate the rate of the hydrogen peroxide decomposition.

- Chemical labeling of chymotrypsin by the compound tosylphenylalanine chloromethyl ketone (TPCK) modifies the His 57 in the enzyme's active site. The structure of this derivative is shown below. TPCK inactivates the enzyme because the bulky addition prevents it from cleaving nearby covalent bonds. HCI + CH, C-O Chymotrypsin-His 57 TPCK Modified enzyme True O Falsearrow_forwardLess energetic electrons. Why are electrons carried by FADH 2 not as energy rich as those carried by NADH? What is the consequence of this difference?arrow_forwardHelp please. This question is specifically asking for the identification of the biomolecules that are attached to the sphingosine core, then we need to answer what bond causes those biomolecules to be connected to the sphingosine, what reaction created that bond (maybe addition or oxidation etc.), what were the starting materials and lastly what reagents or conditions are needed for the reaction to occur. Thank you!arrow_forward

- O BIOCHEMISTRY Understanding major biochemical energy storage and release. A certain anabolic biochemical reaction A has AG- 17.8 kJ mol , and is always coupled to another reaction B, which has two reactants and two products, I this: R + R2 P + P2 The molecule in the drawing area below is either R, or P. • If it's R, change it into P. But if it's P, change it into R. • In either case, draw the molecule as it would exist at physiological pH. • Also please answer the questions about Reaction B in the table below. OR, Was the molecule in the drawing area R, or P, before you changed it? What is R? Enter its common name, usual symbol, or chemical formula: What is P2?
