Biology 107 Midterm Review Sheet Dr. Torah Kachur Below is a set of Objectives and Study Exercises to focus your studying for the Biology 107 midterm. This is NOT ALL that you need to review but does outline major concepts that were focused on in the course. Try not to look at your notes when fillingthis out! These questions are NOT representative of exam-style questions – they are very broad and vague – use them to get you thinking not just memorizing. Good luck studying and, as always, contact me if you have any questions. Lecture 1 Objectives  Outline the characteristics of life  Explain the current criteria of classification and its logic  Draw and discuss the significance of the tree of Domains  Describe the differences between Archaea, Bacteria and Eukarya  Give an example of both prokaryotic and eukaryotic organisms Study Exercises: Draw a tree outlining the relationship of Archaea, Bacteria and Eukarya. What is the evidence for this classification? Fill in the following table Characteristic Bacteria Archaea Eukarya Nuclear envelope Membrane enclosed organelles Peptidoglycan in cell walls Circular chromosome Lecture 2 Objectives  Classify different macromolecules  Identify the subunits of each macromolecule  Describe 2 functions for each class of macromolecule  Identify the bond type between each subunit  Be able to draw the chemical structure of the backbone of the amino acids  Give an example of each class of macromolecule Study Exercises: Fill out the following table Polymer / Macromolecule Type of Carbohydrate Protein Lipid Nucleic Acid macromolecule Monomer Example Elemental composition Bond type Function(s) Draw one amino acid from each classification group and cysteine. Identify the backbone, R group and defining features. Explain the reason for classification. Explain the Watson and Crick model of DNA. Outline – directionality of strands, type of helix, base pair structures, base composition and function of DNA. Explain how lipids are classified, name at least 3 lipids and their respective functions. Outline the basic steps of protein folding and explain the driving forces and stabilizing forces at each stage of protein folding. Lecture 3 Objectives  Outline the basic properties of cells  Describe, in detail, the phospholipid bilayer and identify its components  Draw an intact biological membrane and all of its components  Know the difference between peripheral and integral membrane proteins  Describe how cholesterol maintains membrane fluidity  Describe 4 different ways to get a solute across the membrane  Understand the difference of passive and active transport mechanisms  Understand the contributions and influence of both electrical and chemical gradients  Determine which molecules are permeable and those that are not to the biological membrane  Determine which molecules require enzymes and energy to transport across the membrane Study Exercises: Draw the Fluid Mosaic Model of the phospholipid bilayer. What properties of phospholipids allow for formation of the bilayer? Whatforces stabilize the bilayer? What components differ between plant and animal cell membranes? Explain how temperature affects membrane structure. What adaptations have cells made to survive at both extreme high and extreme low temperatures? Why? Which types of molecules are permeable to the membrane? Impermeable? Why? Explain the difference between passive transport and facilitated diffusion. Draw the sodium/potassium pump including type of transport, numbers of ions transported, direction of concentration gradient, energy source and net result. Why does a cell undergo this process? Why does a cell undergo bulk transport? What mechanisms are used? What are the similarities and differences between phagocytosis, exocytosis and receptor-mediated endocytosis? Give one example given in class of co-transport. Lecture 4 Objectives  Identify common organelles between prokaryotes and eukaryotes  Explain why bacteria are limited in cell size compared to prokaryotes  Draw and describe prokaryotic motile structures  Explain how prokaryotic cells perform cell activities without membrane bound
