A POGIL activity regarding cellular respiration with an additional activity regarding the function of NAD+ in redox reactions.
Seeing that the surface area to volume ratio of cells generally decreases as cells get larger, making the exchange of resources, waster and heat more and more difficult.
This course will introduce you to a general overview of the biological world. Important concepts will be reinforced and expanded upon through completion of weekly laboratory activities and homework assignments. Upon successful conclusion of the course, students will be able to do the following: Describe the nature of science, including its methods and its limitations; Describe the basic methodology of doing science and the scientific method; Use the scientific method to study everyday situations as well as in laboratory/field investigations; Identify, describe, and explain at a rudimentary level and present examples of, the characteristics common to all living things; Explain that living organisms are composed of molecules which interact in a variety of different chemical reactions necessary to sustain life; Explain that living organisms are comprised of one or more cells and are classified as prokaryotic or eukaryotic based on cellular characteristics; Describe the hereditary information possessed by living and explain how that information determines the cellular characteristics and functions (including basic Mendelian genetics); Explain and describe, with examples, the diversity of life, at different levels (basic molecular to ecological) and how it is hierarchically organized into systems; Explain how evolution by natural selection occurs, and describe the evidence that supports the theory of evolution; and more.
All cells, organs and tissues of a living organism are built of molecules. Some of them are small, made from only a few atoms. There is, however, a special class of molecules that make up and play critical roles in living cells. These molecules can consist of many thousands to millions of atoms. They are referred to as macromolecules (or large biomolecules).
