Select true if the statement is CORRECT and false if OTHERWISE   1. Enzymes are catalysts and increase the speed of a chemical reaction without themselves undergoing any permanent chemical change. 2. Catalysis is defined as the acceleration of a chemical reaction 3. if the amount of the enzyme is kept constant and the substrate concentration is then gradually increased, the reaction velocity will decrease.

Hi I have this question, can you help me?

If each assay used 0.10 mL of an enzyme solution that had a concentration of 0.20 mg/mL, what would be the turnover number if the enzyme had a molecular weight of 128,000 g/mol?

KM is equivalent to the substrate concentration multiplied by the ratio of rate constants for the formation and dissociation of the enzyme-substrate complex. KM is equivalent to the substrate concentration. KM is equivalent to the substrate concentration divided by 2 A: KM is equivalent to the substrate concentration…

Please answer asap and in short

Please complete Boothe parts of part B thoroughly with detailed explanations since only part A was done already. Thank you

PLEASE ANSWER C AND D IN QUESTIONS ASKED AT THE END BASED ON GIVEN INFORMATION 1. The Effect of Various Factors on the Rate of an Enzyme Reaction. These experiments will use the enzyme catalase, which is found in potatoes. Catalase acts on the substrate, H2O2 (hydrogen peroxide), to produce H2O and O2. The O2 is released as bubbles. Therefore, the more bubbles you see, the greater the reaction. Base your responses on the following data table: The effect of pH on the rate of enzyme reactions   Tube pH Prediction - no bubbles + some bubbling ++ strong bubbling +++ very strong bubbling Observation - no bubbles + some bubbling ++ strong bubbling +++ very strong bubbling 1 3 - - 2 5 - - 3 7 + ++ 4 9 - +++ 5 11 - +   A. What is the ideal pH for the enzyme catalase? Ans: 9 B. What happens to enzyme activity when the pH is significantly higher or lower than the ideal pH Low enzymatic activity at significantly higher or lower pH.…
