Test Bank for Essential Cell Biology 5th Edition Alberts Hopkin ESSENTIAL CELL BIOLOGY, 5th EDITION CHAPTER 1: CELLS: THE FUNDAMENTAL UNITS OF LIFE Unity and Diversity of Cells 1-1 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 desc...

integral proteins - correct answer Penetrate the hydrophobic interior of the lipid bilayer. Commerce via facilitated or active. peripheral protein - correct answer A protein loosely bound to the surface of a membrane or to part of an integral protein and not embedded in the lipid bilayer. Carbohydrate group - correct answer Linked with protein or lipids and function as adhesion. Cholesterol - correct answer Steroid common in cell membranes, also in many hormones. Functions as suppor...

Electron repulsion theory (VSEPR) - correct answer Electrons are negative, so they will repel each other. Electrons around the central atom determine the shape. The electrons will try and be as far apart from each other as possible. Linear - correct answer AX2, bond angle 180, eg. CO2. Non-linear - correct answer AX2, bond angle 104.5, eg. H2O Trigonal planer - correct answer ...
