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 ...

TEST BANK FOR ESSENTIAL CELL BIOLOGY 5TH EDITION BY BRUCE ALBERTS, ALEXANDER D JOHNSON, DAVID MORGAN, MARTIN RAFF, KEITH ROBERTS, PETER WALTER ISBN 9780393691092 Living systems are incredibly diverse in size, shape, environment, and behavior. It is estimated that there are between 10 million and 100 million different species. Despite this wide variety of organisms, it remains difficult to define what it means to say something is alive. Which of the following can be described as the smallest liv...

USABO Latest Update with Verified Solutions Eukaryote An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure thats sets them apart from prokaryotic cells is the nucleas or nuclear envelope within which the genetic material is carried. All species of large complex species are eukaryotes, including animals, plants and funghi. Euchromatin This shows as pale areas in the nucleas under electro magnification. It is a less densly...
