In Chapter 6, Respiration and Fermentation, the concept of cellular energy was introduced.
In this chapter, you learned that ATP is the most common physiological "currency" used within
the body. You also learned that ATP is most frequently generated from glucose though, in
other organisms, a process known as fermentation is employed. The Websites listed below
should be used as supplements to the information you obtained on cell metabolism as well as
the distribution of energy to generate DNA, RNA, protein, and other cellular macromolecules.
6.1 Why Cells Need ATP
ATP and Biological Energy
This article explains how a group of researchers put together an artificial light-gathering ATP production cell. Designing such artificial energy-producing cells has enormous technological potential for both industry and human medicine.
Keywords: ATP synthase, biological energy, photosynthesis
6.2 How Is Sugar Converted to Carbon Dioxide?
Metabolic Pathways
This site is a wonderful resource for scientists and students wishing to learn more about
glycolysis, fermentation, the Krebs cycle, and the electron transport chain.
Keywords: metabolic pathways, glycolysis, fermentation
6.3 Krebs Cycle
Glycolysis and the Krebs Cycle
This site, from Massachusetts Institute of Technology, links to references on glycolytic
metabolism, the intermediates of glycolysis, a well-presented diagram of the electron
transport chain, and a summary of energy created from ATP.
Keywords: glycolysis, electron transport chain, and ATP
Biochemical Metabolism
This site is another good resource for following the oxidation-reduction reactions that
sugar molecules undergo during metabolism. Several different molecules in the pathway of
metabolism can be viewed with the CHIME plug-in.
Keywords: metabolic route, glucose, Krebs cycle
6.4 Electron Transport and Chemiosmosis
ATP Synthase in Action
Electron Transport and Chemiosmosis, a proton gradient within the mitochondria drives
the formation of ATP. This site from the University of Connecticut includes terrific
imagery and animations of ATP synthase in action.
Keywords: ATP synthase, ATP, mitochondria
6.5 Fermentation
The Miracle of Fermentation
This animation site from Cornell University displays the process of glycosis and fermentation.
It is a good review for both the basic steps of glycolysis and the way in which fermentation
allows glycolysis to continue.
Keywords: glycolysis, ATP, ADP, fermentation
Cellular Process
This site provides an overview of the process of cellular respiration. Follow the
"Fermentation" link to learn more about the cellular processes of anaerobic metabolism.
Keywords: glycolysis, aerobic respiration, fermentation.
Exercise
This site, from How Does it Work.com, discusses exercise physiology and metabolic energy
production. Follow the links to learn about getting oxygen to the cells quickly and
efficiently, training your body, and the relationship between good nutrition and healthy
athletic metabolism.
Keywords: ATP, exercise, oxygen
