Document Summary

Chapter 1 cells: the fundamental units of life: micrometer : cells are commonly measured in micrometer 10^-6 or nanometer 10^-9, dna, rna, protein , cell : fundamental units of life, cells are highly complex and organized. Cells from different species share similar structure, composition and metabolic features that have been conserved throughout evolution. Cells are capable of producing more of themselves. Chapter 2 chemical components of cells: molecular weight; is the mass of a molecule, chemical bond ; atoms are held together by bonds to make molecules, molecules interact with each other using bonds, mostly based on charge separation. A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds. They do not involve sharing a pair of electrons. Polar bonds are usually liquids or solids and are soluble: hydrogen bond ; are important noncovalent bonds. These kinds of bonds occur mainly between a metallic and a non metallic atom.
