Principles of Ecology Organisms and Their Environment What is Ecology? Ecology: the study of interactions that take place between organisms and their environment The Biosphere Biosphere: the part of Earth that supports life The biosphere includes the top portion of Earth?s crust, all the waters that cover Earth?s surface, and the atmosphere that surrounds Earth. The biosphere is made up of different environments that are home to different kinds of organisms. Ecosystem: all the living organisms living in an area and the nonliving features of their environment Biotic factors: living organisms in an ecosystem (ex. bison, grass, birds, insects) Abiotic factors: nonliving features of an ecosystem (ex. water, temperature, sunlight, soil, air) Levels of Organization

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.

Nutrition In order for the human body to be healthy and resistant to disease, good nutrition is required. All living things are made of chemicals. In order to grow, develop and maintain bodily structures and functions, specific chemicals must be acquired from the food we eat. In a sense, we are what we eat. Nutrients can be divided into the following categories: Nutrients Overview Carbohydrates ? sugar based molecules that are metabolized for energy in cellular respiration and make up the structural components of plant cell walls. Lipids ? fat based molecules that store large quantities of energy. These molecules also make up the structure of cell membranes.

Cellular Respiration Plant cells harvest energy from the sun, and store it as glucose. That glucose must be transformed into energy the cell can use, specifically ATP. This takes place in the mitochondria of cells. There are two ways that a cell can harvest energy from the food (glucose) it takes in: Anaerobic Cell Respiration (Fermentation) ? glucose metabolism in the absence of oxygen that produces 2ATP molecules and either ethanol or lactic acid. Involves 2 stages: Glycolysis Fermentation Aerobic Cellular Respiration ? glucose metabolism with oxygen that produces 36 ATP molecules, CO2 and H2O. Involves 4 stages: Glycolysis Pyruvate oxidation Krebs cycle Electron transport and chemiosmosis Stage 1 ? Glycolysis
