MATCH COLUMN WITH THE BEST ANSWER IN COLUMN II: enzymes location of the chemical reaction on an enzyme substrates reactants in an enzyme catalyzed reaction catalyst ions or small organic molecules required for the specific activity of certain enzymes active site biochemical catalyst cofactors lowers the energy of activation 1^st law of thermodynamics negative feedback observed in enzymatic reactions protein kinase energy liberated from a reaction provides the energy required in another reaction end-product Inhibition enzyme class that adds phosphate groups turnover number number of biochemical reactions per unit time coupled chemical reactions energy can neither be created or destroyed Which of these statements about enzymes is TRUE? Most proteins are enzymes. Most enzymes are proteins. Enzymes are changed by the reactions they catalyze The active sites of enzymes have little specificity for substrates.Explanation / Answer
Answer
Matching of column first
1. Enzyme D. Biochemical Catalysts
2. Substrate B. Reactant in an enzyme-catalyzed reaction
3. Catalyst E. Lowers the activation energy
4. Active Site A. Location of the chemical reaction on a enzyme
5. Cofactors C. Ions or small organic molecules required for the specific activity og certain enzymes
Matching of column second
6. 1st Law of thermodynamic E. Energy can neither be created nor destryed
7. Protein kinase C. Enzyme class that adds phosphate groups
8. End-product inhibition A. Nagative feedback observed in enzymatic reactions
9. Turnover number D. Number of biochemical reactions per unit time
10. Coupled chemical reactions B. Energy liberated from a reaction provides the energy required in another reaction
Multiple choice question
Option B
Most enzymes are proteins. Because enzymes are made up of proteins, but there are a few enzymes are are composed of RNAs. these enzymes are called as ribozymes
