BIO 311C Study Guide - Comprehensive Final Exam Guide - Adenosine Triphosphate, Protein, Glucose
Document Summary
Proteins: made up of amino acids; amine group nh3. Spontaneous generation doesn"t exist all life comes from previous generation and there is a common ancestor of all life. Biosphere -> ecosystem ->communities -> populations -> organisms -> organs and organ systems -> tissues -> cells -> organelles -> molecules. Emergent properties properties which a complex system has, but which the individual members don"t have. Ex: water surface tension, which hydrogen and oxygen don"t exhibit by themselves. Electronegativity: the closer the two atoms in their electronegativities, the more equal their sharing of. Ionic bond transfer of electrons to form ions. Covalent bond sharing of a pair of electrons: link atoms to form molecules. Biologists think covalent bonds are stronger because water can break ionic bonds easily. + - present in amino acids, proteins and nucleic acids: sulfhydryl sh most reactive, present in proteins, phosphate po4, methyl ch3 present in lipids, proteins and nucleic acids.
