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.

EXPLORING PROTEIN STRUCTURE Discuss the properties of the following fibrous proteins in relation to their structure and function: Collagen Fibroin Keratin Some globular proteins, such as actin, can link together to form filaments. Discuss the importance of this property for cells. Discuss how the microtubules of the cell cytoskeleton form. Relate this structure to the function of the cell cytoskeleton. Enzymes are globular proteins that catalyse reactions in a highly specific manner. Discuss how catalase increases the rate of reaction for removing hydrogen peroxide from cells so it does not reach toxic levels.
