Campbell's Biology, 9e (Reece et al.) Chapter 5 The Structure and Function of Large Biological Molecules In Chapter 5, the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers, and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure, because this is central to understanding subsequent chapters on metabolism, molecular biology, and molecular medicine. Multiple-Choice Questions 1) Humans and mice differ because A) their cells have different small organic molecules. B) their cells make different types of large biological molecules.

Campbell's Biology, 9e (Reece et al.) Chapter 1 Introduction: Themes in the Study of Life This introductory chapter explores the basic themes and concepts of biology, with emphasis on the core theme of evolution. It also introduces students to the thinking of scientists. Questions are therefore general; however, an effort has been made to include some from each skill level. As in the rest of this test bank, questions that feature art or those for which several questions follow upon some data or a scenario are placed together at the end of the chapter. Multiple-Choice Questions 1) A localized group of organisms that belong to the same species is called a A) biosystem. B) community. C) population. D) ecosystem. E) family. Answer: C Topic: Concept 1.1

Ian Konrad 4-23-14 LEH Mrs. Guido Flower Anatomy Activity 1a. Record the number of sepals observed in your flower specimen and give 1 function. There were 12 sepals on my flower. One function of the sepals is to protect the flower while it is forming a bud. 2a. Record the number of petals - what advantage do colorful petals provide for the flower? There were 6 petals on my flower. Colorful petals attract pollinators such as bees to come and pollinate the flower. 2b. Why are sepals considered accessory parts of the plant? Sepals are considered accessory parts of the plant because they are not directly involved in pollination. 3a. Record the number of stamens and give 1 function.

Chapter 4: A Tour of the Cell Types of Cells Prokaryotic- a type of cell lacking a membrane-enclosed organelles Bacteria and Archaea DNA in the nucleoid which is not membrane-bound Eukaryotic- a type of cell with membrane bound organelles Protists, Plants, Fungi, and Animals Contian a membrane-bound nucleus Contain organelles and cytoplasm Both: Have ribosomes Plasma membrane Jelly-like cytosol Chromosomes *As the volume of a cell grows, the surface area increases proportionally because more plasma membrane needed to transfer necessary materials for the metabolic processes *Different organelles increase complexity of the cell because each organelle has a specific function, whit allows multiple activities to be going on in the cell at once The Nucleus

Chapter 4: Carbon and the Molecular Diversity of Life 4 Major Macromolecules: Lipids Carbohydrates Nucleic Acid Protein Lipids Fat- a combination of a glycerol and three fatty acids also called a triglyceride Used for long term energy storage, which is located in the long carbon chains Phospholipid- a combination of a glycerol, two fatty acids and a phosphate group Makes up cell membrane (lipid bilayer) Selectively permeable Hydrophilic heads (the phosphate group) Hydrophobic tails Steroid- lipids with a structure of four fused rings General Information Glycerol is combined to fatty acid by an ester linkage (dehydration synthesis) Ester linkage is polar CH2 groups are nonpolar Saturated Fat- a triglyceride with only single bonds

Chapter 5: Membrane Transport and Cell Signaling Amphiphatic- refers to something that has both hydrophilic and hydrophobic regions the cell membrane proteins Fluidity Low Temperatures-less fluid because the phospholipids pack together tightly Factors that Affect Fluidity: Amount of phospholipids- phospholipids have kinks in the tails due to their hydrogen bonds which make them harder to pack Cholesterol- inhibits the packing of the phospholipid tails at LOW TEMPERATURE. AT HIGH TEMPERATURE, it solidifies the membrane because it inhibits the movement of tails Proteins in the Membrane Intergal-penetrate the membrane, hydrophobic exterior, hydrophilic interior Peripheral-lie on either side of the membrane Major Protein Functions: -Transport-allows materials to diffuse

Chapter 10 Photosynthesis Overview: The Process That Feeds the Biosphere Photosynthesis Is the process that converts solar energy into chemical energy Plants and other autotrophs Are the producers of the biosphere Plants are photoautotrophs They use the energy of sunlight to make organic molecules from water and carbon dioxide Figure 10.1 Photosynthesis Occurs in plants, algae, certain other protists, and some prokaryotes These organisms use light energy to drive the synthesis of organic molecules from carbon dioxide and (in most cases) water. They feed not only themselves, but the entire living world. (a) On land, plants are the predominant producers of food. In aquatic environments, photosynthetic organisms include (b) multicellular algae, such

Chapter 14 Mendel and the Gene Idea Overview: Drawing from the Deck of Genes What genetic principles account for the transmission of traits from parents to offspring? One possible explanation of heredity is a ?blending? hypothesis The idea that genetic material contributed by two parents mixes in a manner analogous to the way blue and yellow paints blend to make green An alternative to the blending model is the ?particulate? hypothesis of inheritance: the gene idea Parents pass on discrete heritable units, genes Gregor Mendel Documented a particulate mechanism of inheritance through his experiments with garden peas Figure 14.1 Concept 14.1: Mendel used the scientific approach to identify two laws of inheritance Mendel discovered the basic principles of heredity
