Document Summary

Chapter 3: questions, organic substances with a carbon to hydrogen to oxygen ratio of 1:2:1 are: i. ii. iii. iv. Lowering activation energy: cells, the basic structural & functional unit of living organisms, organism activity depends upon the individual & collective activities of its cells, the biochemical activities of cells are dictated by their shape and number, continuity of life from generation to generation has a cellular basis, two types of cells: sex cells & somatic cells, the plasma membrane, the outer boundary of the cell, physical isolation, separates inside of cell from extracellular fluid, regulation of exchange with the environment, selectively permeable (important, sensitivity to the environment, structural support, membrane lipids. Hydrophobic tails form interior of membrane: glycolipids (outer surface) & cholesterol, water and solutes can not cross lipid portion of the plasma membrane, the plasma membrane isolates the cell from its environment and performs varied functions, membrane proteins, denser than lipids i.
