Fermentation
A metabolic process that converts sugars to acids, gases, or alcohol in the absence of oxygen.
Glycolysis
The metabolic pathway that converts glucose into pyruvate, producing a small amount of energy.
Krebs Cycle
Also known as the citric acid cycle, it is a series of chemical reactions used by all aerobic organisms to generate energy.
Acetyl CoA
The starting molecule of the Krebs cycle, derived from the breakdown of carbohydrates, fats, and proteins.
Cellular Respiration
The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
Energy Release During Cellular Respiration
Energy is released when glucose is broken down during cellular respiration.
Photosynthesis
The process through which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, which does not release energy from glucose.
Pacing in Athletic Events
Athletes must pace themselves because cellular respiration releases energy more slowly than fermentation.
Glucose in Glycolysis
Glucose is NOT a product of glycolysis; it is the starting molecule.
Aerobic Process
A process, such as cellular respiration, that requires oxygen.
