Cellular respiration is a key concept to understand in biology as it involves obtaining energy from the nutrients organisms eat and the removal of waste products. It is a key biological process which is vital to all life forms, including humans. In this free online biology course you will learn about the chemical makeup of the energy that is stored, generally referred to as adenosine triphosphate (ATP), how this molecule works and how it is used in the respiratory process. You will also learn about glucose as it is the main source of energy, and the stages involved in cellular respiration from glycolysis through the Kerb’s cycle to the electron transport chain. You will learn how molecules are split to release energy through oxidization to produce ATP and waste products in the form of water and carbon dioxide. This free online biology course will be of great interest to all students who wish to pursue a career in sciences such as biology, biochemistry, medicine, pharmacy or the individual learner who simply wants to learn more about how we convert our food into energy.<br />

This course provides an introduction to the environmental aspects of sustainability, including renewable energy techniques, the impact of nonrenewable sources, air quality, storm water management, land use, and the built environment. Topics include climate change and greenhouse gases; wind, solar, water, and geothermal energy; bio-fuels; conservation techniques; global demand; legal and regulatory aspects; and job creation. After completing this course, students will be able converse knowledgeably about the broader context of sustainability and environmental impacts, social consequences and financial opportunities.

In this six-week course, you will learn the basics about our energy and climate obligations. You will also prepare yourself to continue learning as these issues evolve. You will evaluate demand-side (e.g. more efficient buildings and automobiles) and supply-side (e.g. solar and wind) strategies for more sustainable use of energy. The course will require fact-based analysis of our energy obligations and possible ways to meet them. Please also consider enrolling in Sustainable Energy Innovation which begins June 2.

This course is designed to help you get started as a behavioral science student, become familiar with the academic programs within the field, and prepare you for your first meeting with your academic advisor or academic counselor once you make your decision about which program to pursue.

This introductory course defines biology and its relationship to other sciences. We examine the overarching theories of life from biological research and also explore the fundamental concepts and principles of the study of living organisms and their interaction with the environment. We will examine how life is organized into hierarchical levels; how living organisms use and produce energy; how life grows, develops, and reproduces; how life responds to the environment to maintain internal stability; and how life evolves and adapts to the environment. This course is a part of our Community College (CC-OLI) series. Courses in this series are particularly well-suited to the needs of introductory community college courses, but are open for use by any instructor or student.

Cell physiology is the branch of science that studies the structure and function of individual cells. Our increasing knowledge and understanding of cellular mechanisms and processes have led to great advances in all areas of biology and medicine. In this free online physiology course you will be introduced to the main topics in cell physiology such as the major components of a typical animal cell. You will learn about the mechanisms behind cell growth and multiplication, about the movement of substances into and out of cells, how energy is processed within the cell, and how and why cells maintain an electrical charge across their membranes called membrane potentials. This free online cell physiology course will be of great interest to all healthcare professionals who would like to learn more about the structure and function of cells, and to all students of biology and medicine who would like a greater knowledge and understanding of the mechanisms and processes involved in cell physiology.<br />

This is a complete course in chemical stoichiometry, which is a set of tools chemists use to count molecules and determine the amounts of substances consumed and produced by reactions. The course is set in a scenario that shows how stoichiometry calculations are used in real-world situations. The list of topics (see below) is similar to that of a high school chemistry course, although with a greater focus on reactions occurring in solution and on the use of the ideas to design and carry out experiments. Note: Our chemistry courses are about to be improved and expanded! Thanks to upcoming support from the NSF, a project to further improve online chemistry education will result in new and improved materials delivered through OLI. New materials will be available from 2012 through 2014!
