Chapter 8: Harvesting Energy: Glycolysis and Cellular Respiration Links

With each inhalation, we breathe in oxygen that is delivered to the mitochondria in our cells. How is this oxygen used? Where does the carbon dioxide we breathe out come from? Explore these Web sites for answers to these questions and lots more!

1) How Is Glucose Metabolized?

ATP and Cellular Energy

What is ATP, and how does it provide energy for cells? Find out here.

Cellular Respiration

This site from University of Cincinnati Clermont College provides a comprehensive overview of cellular respiration and fermentation.

Glucose Metabolism

What happens if you get lost in a deep cave and are waiting for rescue? This interesting essay describing general human metabolism is aimed at "cavers" (people who explore caves), but it is just as applicable to the rest of us!

2) How Is the Energy in Glucose Harvested During Glycolysis?

Glycolysis

This Web page provides a good general description of glycolysis and fermentation.

Introduction to Glycolysis

You will find a straightforward description of glycolysis at this site.

3) How Does Cellular Respiration Generate Still More Energy from Glucose?

Animations of Mitochondria Function

These animations provide dynamic illustrations of how mitochondria produce ATP.

Cellular Respiration

This Web page provides a comprehensive description of how mitochondria produce ATP. There are also links to discussions of glycolysis.

Hummingbirds

Information and links about hummingbirds, one of the most efficient producers (with a backbone) of ATP, is presented here.

1997 Nobel Prize in Chemistry

The Nobel Prize in chemistry in 1997 was awarded in part to Paul Boyer and John Walker for their work on how mitochondria produce ATP. This Web page describes their work, including the interesting possibility that ATP synthesis involves a molecular "rotary engine."

Mitochondria

What does a mitochondrion look like? This site has diagrams and electron micrographs of mitochondria, as well as an excellent overview about the role of mitochondria in cell respiration.

Nutrition Links

This site maintains an extensive array of links to Web pages that relate to various nutrition issues.
