Key Vocabulary in Biology

Anaerobic
- Refers to processes that occur without the presence of air or oxygen.
Aerobic
- Describes processes that take place in oxygen-rich environments.
Glycolysis
- A metabolic pathway that breaks down glucose into two molecules of pyruvic acid, generating energy in the form of ATP.
Matrix
- The innermost compartment of a mitochondrion, playing a critical role in energy production.
Calorie
- The amount of energy required to increase the temperature of 1 gram of water by 1 degree Celsius, commonly used as a measure of energy content in food.
Fermentation
- A metabolic process that converts sugar to acids, gases, or alcohol in the absence of oxygen, resulting in either lactic acid or ethyl alcohol.
Krebs Cycle
- A key phase of cellular respiration initiated by pyruvic acid, resulting in the production of carbon dioxide and energy-rich electron carriers.
Glycolysis (repeated)
- This term also refers to the process that releases energy by breaking down food molecules in the presence of oxygen, contributing to aerobic respiration.
ATP (Adenosine Triphosphate)
- The main energy currency of the cell, serving as an electron carrier that accepts electrons during glycolysis.
Opposite Processes
- Cellular respiration and photosynthesis are complimentary processes; respiration converts glucose into energy while photosynthesis uses sunlight to create glucose.
