Mod 5B - Cell Energy
Second Half Module 5 - Cellular Energy
Term | Definition |
---|---|
Calvin Cycle | aka "Light Independent Reactions"; cycle of chemical reactions performed by plants to “fix” carbon from CO2 into three-carbon sugars |
Carbon Fixation | carbon from CO2 is fixed from an inorganic to an organic molecule when it combines with an organic five-carbon compound called RuBP |
Aerobic | Requiring oxygen |
Anaerobic | without oxygen |
Activation Energy | the energy needed to get reactions started |
Glycolysis | the first stage of cellular respiration where glucose is split in half |
Krebs cycle | the stage of cellular respiration where carbon dioxide is used to complete the breakdown of pyruvic acid molecules, releasing energy |
Carboxyl group | aka acid group; organic acid containing a carbon atom single bonded to a hydroxide ion and double bonded to an oxygen. All amino acids contain this |
Fermentation | a cellular process producing ATP without oxygen |
