Term
Photosythesis
Definition
the process where autotrophs use light energy from sunlight and convert it into chemical energy. CO2 + H2O = C6H12O6 + O2
Term
Light reaction
Definition
light from sun is absorbed by chlorophyll in autotrophs where the energy is transfered to one of the plants electrons. ATP is produced and oxygen is given off by this reaction
Term
Electron transport chain
Definition
where an electron gained by an autotroph is passed along a series of proteins to make ATP.
Term
Calvin Cycle
Definition
Light independent reaction (no light needed) where carbon from CO2 is used in a cycle of reactions to produce glucose for energy.
Term
ATP
Definition
a molecule that is produced by the light reaction of photosythesis that is used in the Calvin Cycle to produce glucose
Term
ADP
Definition
a molecule that gets another phosphate added to it during photosythesis to produce ATP.
Term
Anaerobic respiration
Definition
respirtion without oxygen. Two types Alcohol Fermentation and Lactic Acid Fermintation
Term
Respiration
Definition
proess where all living things process stored energy for use. O2 + C6H12O6 + H2O + CO2.
Term
Glycolysis
Definition
The anarobic stage of respiration where 2 ATP molecules are made
Term
Citric acid cycle
Definition
a stage of respiration whereoxygen is used, CO2 is released and ATP is made
Term
Lactic Acid Fermentation
Definition
glucose - glycolysis - lactic acid + ATP
Term
Cellular respiration
Definition
the most efficient form of ATP production
