Which of these is NOT a correct statement about enzymes?   Group of answer choices   Enzyme activity may require a non-protein component (cofactor).   Enzymes catalyze chemical reactions and are reusable.   Enzymes increase the activation energy (Eact) of reactions.   Enzyme activity is affected by the environment (e.g., temperature and pH

Some protein enzymes require RNA cofactors in order to function. Group of answer choices True False

Classify each phrase as describing an enzyme, an active site, or a substrate. Enzyme may be a phosphate group a protein containing an active site a substance that the enzyme acts upon a biological catalyst Active site Answer Bank Substrate a specific enzyme location that binds with the substrate

Figure #1 and #2 show the results collected from a fun enzyme activity lab that did NOT involve the liver;) Answer the questions that follow. REACTION RATE (mg/sec) -1 m O 0 1 2 3 4 5 6 Rate of Reaction Enzyme A Rate ofreaction pH Figure #1 pH and enzyme reaction rate 0 10 7 8 9 10 11 12 13 14 Enzyme B Temperature 35 40 Enzymes A and B Figure # 2 The effect of temperature (°C) on enzyme activity a. Looking at these results, could these enzymes (A and B) be found somewhere in the human body? If so, where? Explain your answer, and be sure to discuss both factors (pH and temperature) as they relate to enzyme activity/rate of reaction.
