Why are enzymes really good catalysts? Correct Answer-Because enzyme active sites have evolved to catalyze reactions with maximum efficiency by using several catalytic mechanisms simultaneously Enzymes exhibit maximal activity under what kind of conditions? Correct Answer-Mild conditions, like conditions that exist in cells. Why are enzymes categorized as being extremely specific? Correct Answer-Because an enzyme usually catalyzes ONLY the reaction involving "its" substrate, even though ...

What six functions characterize all living things? Organization Responsiveness Growth Reproduction Movement Metabolism/Excretion What is homeostasis? A steady state of internal environment of an organism. What is the difference between positive and negative feedback? Give an example of each. Positive feedback enhances change (labor contractions during birth, blood clotting, etc...) Negative feedback resists change (body temperature, insulin, cortisol, etc...) List...

What is one requirement for life? correct answers The ability to efficiently an selectively catalyze chemical reactions Most biomolecules are very stable. What does this mean in terms of permitting life? correct answers Uncatalyzed transformations would be too slow to permit life What do enzymes provide a mechanism for? correct answers The regulation and coordination of these reactions What is vitalism? correct answers Belief that living things are fundamentally different from non-livin...
