"We now understand a lot about cancer. We know that it results from a series of genetic changes having to do with cell division and growth control and genetic instability, mortality, the suicide mechanism in cells; the ability of the cells to migrate; the ability of the cells to attract to them a blood supply. And so that's pretty profound that in a few sentences one can summarize a sophisticated, fundamental understanding of what a cancer is." -- Leland Hartwell Introduction
Cellular respiration is the process by which the chemical energy of "food" molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved. Since most textbooks provide abundant details of the chemical reactions in respiration, this tutorial will focus on how the chemical energy in glucose is converted into ATP and where respiration occurs in the cell. <p style="text-align:right;color:#A8A8A8"></p>
by Drs. Ingrid Waldron and Jennifer Doherty, University of Pennsylvania The expression " hands-on, minds-on " summarizes the philosophy we have incorporated in these activities -- namely, that students will learn best if they are actively engaged and if their activities are closely linked to understanding important biological concepts . For example, it is helpful to use hands-on models to engage student interest and foster multiple modality learning, but it is crucial to closely link the modeling activity to student understanding of the actual biological processes.
Sarah M. Boomer * , Kristin L. Latham Department of Biology, Western Oregon University, Monmouth OR 97361. The first course in our year-long introductory series for Biology majors encompasses four learning units: biological molecules and cells, metabolism, genetics, and evolution. Of these, the metabolism unit, which includes respiration and photosynthesis, has shown the lowest student exam scores, least interest, and lowest laboratory ratings.
Welcome to the Teachers' Center at Explore Biology. Here you will find resources to help you teach biology at the high school level. Some of my Regents lectures are supported by Powerpoint presentations . If you are not familiar, Regents is a 10th grade very simplified introduction to Biology, that is limited by a state-wide exam.
Scitable is a free science library and personal learning tool brought to you by Nature Publishing Group, the world's leading publisher of science.
