This is a comprehensive textbook covering life functions that are ultimately interpretable in chemical terms, as chemistry is the logic of biological phenomena.
This 13-minute video lesson provides an overview of glycolysis. [Biology playlist: Lesson 24 of 71].
This 14-minute video lesson presents an introduction to cellular respiration, glycolysis, the Kreb's Cycle, and the electron transport chain. [Biology playlist: Lesson 21 of 71].
In this unit, students look at the components of cells and their functions and discover the controversy behind stem cell research. The first lesson focuses on the difference between prokaryotic and eukaryotic cells. In the second lesson, students learn about the basics of cellular respiration. They also learn about the application of cellular respiration to engineering and bioremediation. The third lesson continues the students' education on cells in the human body and how (and why) engineers are involved in the research of stem cell behavior.
In this lesson, students learn about the basics of cellular respiration. They also learn about the application of cellular respiration to engineering and bioremediation. And, students are introduced to the process of bioremediation and several examples of how bioremediation is used during the cleanup of environmental contaminants.
This interactive exercise is intended to help you understand why glycolysis has evolved to the form that we can observe in living cells and how it is so efficient that it seems to resemble a designed process. THIS IS NOT A QUIZ - when presented with options you should choose the wrong answers to gain maximum understanding.
Living cells can process certain sugar molecules, rearranging their atoms and this process can supply energy to the cell to power growth and other functions. This process is called glycolysis. Glycolysis evolved billions of years ago when there was no oxygen in the earth's atmosphere and it was therefore impossible for cells to gain energy from the oxidation of sugar molecules using oxygen. Later when oxygen was produced as a byproduct of photosynthesis cells evolved to utilise oxygen to oxidise the product of glycolysis and capture much more energy.
Biochemistry text books will give you the details surrounding the metabolic pathway, glycolysis. This introduction avoids the detail and the individual steps and gives an overview of what glycolysis is all about. I've tried to keep the text short and sweet and to use animations to avoid a lot of verbose explanation.
Equilibrium of biochemical reactions is seldom taught in introductory biology labs. However, equilibrium is an excellent topic for the introduction of simple mathematical modeling into the lab curriculum. When properly done, modeling can allow an exploratory, hands-on approach to equilibrium, as well as teach a valuable application of mathematics. Stella modeling software facilitates the exercise by allowing students to construct sound models without dwelling on mathematical details. This exercise illustrates a modeling approach to reaction equilibrium and some aspects of thermodynamics. We use this exercise in introductory biology laboratories at Clemson University.
