BIOl 213 1st Edition Lecture 2 Outline of Last Lecture I Class introduction A Exams B Grading II Cell and Molecular Biology main points III The Cell Theory A Every living cell comes from another living cell IV Pasteur Experiment A Set up experiment B Results of experiment C Explanation of results D What if Pasteur were wrong Outline of Current Lecture I Review of Pasteurization vs sterilization II DNA replication A Common goal of cells B Compartmentalization in cells III The Atom A Bonds covalent and ionic IV Water A Properties B What if these properties weren t true V Weaker bonds A Hydrogen bonds B Hydrophobic interactions C Van der Waals interactions VI pH VII The Mole Current Lecture I Review of pasteurization vs sterilization a Pasteurization kills some things i Enough so that it s not dangerous to eat ii Ex milk b Sterilization kills everything These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute II III c Pasteur actually used sterilization in his experiment not pasteurization DNA replication a The common goal of all cells is DNA replication i Just like the common goal of all living things is to reproduce ii DNA is the blueprint for everything in the cell b Every molecule and process in the cell contributes something to this goal i Especially proteins Some examples 1 Transcription 2 Transporters 3 DNA repair c The cell compartmentalizes to save energy i It would cost too much energy to just have everything floating around ii Mitochondria 1 The cells energy source iii Cellular membrane to regulate what comes in and what goes out 1 What goes in and what goes out is usually determined by whether or not it will contribute to DNA replication 2 The cell especially wants to keep energy in 3 There is transportation via a Diffusion b Mediated transportation of things that can t diffuse iv Nucleus 1 Contains the DNA v Cytoskeleton 1 Things are moved throughout the cell
