- Balance the reactions. A hint is provided to help you decide if the reaction will proceed as written, ie from left to right. Do not leave any fractions. 1. a) Balance Al₂O3 → Al + 0₂ b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ? (hint: O₂ is very reactive) 2. a) Balance HNO3 + AI → b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ? (hint: aluminum is a reactive metal, and a gas escapes) C7H14 + 0₂ 3. a) Balance, leave no fractions b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ? (hint: O₂ is very reactive) H2(g) + AI(NO3)3 → CO₂ + H₂Opredict the outcome of the reaction. explain briefly.S 1 CH₂ ✪ NH3 0=0 H₂C HN 6 NH CH₂ 'S Co A L CH₂ NH 4. Describe the role of His in the catalytic mechanism shown.
- 5. You discover a new cysteine protease similar to papain. Cysteine proteases are proteolytic enzymes that utilize a cysteine residue in the active site for the nucleophilic attack of a peptide bond, while a second residue acts as a base for proton abstraction in the reaction (acid base catalysis). In this novel enzyme the pKa of the cysteine residue is significantly lowered by the active site environment to pKa=4. a. Knowing that the protease shows highest activity between pH 4-6, what could be the identity of the base residue acting as a in the reaction? Explain and write the expected mechanism for the reaction.
