BIO101L: Introduction to Molecular and Cellular Biology Lab

Unit 6: Cellular Metabolism   Cellular metabolism consists of glycolysis and cellular respiration.  Our activities in this unit will focus on understanding the process of cellular respiration, what is required for it to occur, and how it can be altered.

Unit 6 Time Advisory
This unit should take you approximately 2 hours to complete.

Unit6 Learning Outcomes
Upon successful completion of this unit, the student will be able to:
- Describe the processes of cellular metabolism. - List the steps of glycolysis and cellular respiration. - Determine the factors that would influence or alter various specific steps of glycolysis and respiration.

    Instructions:  Please read this page to refresh your memory regarding the cellular respiration process, which you learned about in the lecture portion of this course.  Pay special attention to the reactants and products of each reaction that occurs during respiration.  Practice writing out the entire process of respiration on your own, without looking at your notes.

    Instructions: Please click through this tutorial to visually familiarize yourself with the process of cellular respiration.  As you work through this material, think about how each step in the process relies upon the last, and what role environmental factors play in the process.  Then answer the following questions:
    1)    How could you experimentally alter cellular respiration?
    2)    Why might it be beneficial in some situations to do so?
