What is an enzyme? What is activation energy? How are those terms related? Define enzymatic activity
What is the energy of activation? 16. How do enzymes speed the rate of reaction? 17. Talk about the effect of the following on enzyme reaction rate: a) Substrate concentration b) pH c) Temperature 18. How do vitamins play a part in enzymatic reactions?
Part A - Overview of enzyme structure and enzymatic reactions Enzymes are large globular proteins. Much of their three dimensional shape is the result of interactions between the R (variable) groups of their amino acids. The active site is the portion of the enzyme that will interact with the substrate the molecule that the enzyme acts upon. The nature and arrangement of amino acids in the active site make each enzyme specific to a substrate and to the reaction it...
What is activation energy? What effect does on enzyme have on the required activation energy? Give the function of each of the following: (a) coenzyme (b) allosteric site Explain the roles of the following in aerobic respiration: (a) NAD+ (b) oxygen List the end products of glycolysis
Enzymes lower activation energy in a variety of ways. Choose one of those ways and think of how you might explain that concept to a younger sibling. Can you find a particular enzyme that works in that way?
Which enzyme(s) (or enzymatic steps) is(are) likely to be regulatory? O A. those with mass action ratios much less than Keq, OB. the first enzyme in metabolic pathway, OC. the first enzyme unique to a branch in a pathway, OD.those with disequilibrium ratios much less than 1, O E. all of the above, OF. none of the above.
the activation energy di the reaction with an enzyme. the progress of the reaction. All of the following statements regarding the figure are correct EXCEPT? Figure 2. Energy profile of a chemical reaction with and without an enzyme Free Energy Progress of reaction - Even with the addition of an enzyme, an input of energy is needed for the reaction to progress. Energy is released from the reaction with or without an enzyme Even with the addition of an enzyme,...
Question 12 How does an enzyme work to catalyze a reaction? -It lowers the activation energy of a reaction. -It raises the temperature of a reaction. -It supplies the energy to speed up a reaction. -It increases the concentration of the reactants in a reaction. -It allows the reaction to proceed through different intermediates.
