Directions: For this reverse lecture you are going to go through some very basic information reviewing net primary productivity and introducing cellular respiration in the presentation below and the article linked to this site.  Once you have finished the lecture, answer the questions below about the information you have read.  You may have some of this information in your notes from a previous tutorial – if so, use that information as well as the article information to answer the questions.  Don’t worry about writing a lot for each question; just give a short answer showing that you understand the material.  You might want take notes on the information as you go, especially information from the article.

Article: This article is from Georgia State University.  The graphics of the various stages of cellular respiration are interactive, and you can click on any part of the graphics to learn more about that stage of the process.  Use the information in the article and the presentation that you have already read to answer the questions below on this site.

Georgia State University Hyper-Physics: Cellular Respiration

Questions

1. Describe the inputs and outputs of the three stages of cellular respiration:
   1. Glycolysis
   2. The Krebs Cycle (Citric Acid Cycle)
   3. The Electron Transport Chain
2. Explain the function of the electron carriers NADH and FADH2 in aerobic respiration.
3. Compare aerobic and anaerobic respiration in terms of inputs, outputs, and energy produced.
4. Explain the importance of the proton gradient for the production of ATP in the electron transport chain.
