Term
Definition
Chloroplasts   site of the Calvin Cycle  
Cuticle   The waxy top layer of the leaf that prevents water loss.  
autotroph   Organisms that make their own food.  
heterotroph   Organisms that must seek out food sources.  
ATP   A chemical compound that is used by cells to store and release energy.  
Photosynthesis   The process by which autotrophs create food.  
Pigment   Light-absorbing/reflecting molecules. Responsible for the colour of plants  
Chlorophyll   Plant pigment (Chlorophyll A-absorbs blue light; Chlorophyll B-absorbs red light). Neither can absorb green light very well.  
Thylakoid   Saclike photosynthetic membranes.  
Photosystems   Proteins in the thylakoid membrane that organize chlorophyll and other pigments into clusters  
Stroma   The region outside the thylakoid membranes.  
NADP+   Takes in and holds 2 high-energy electrons along with a hydrogen ion.  
Light-Dependent Reactions   Reactions that require light to function  
ATP Synthase   A protein that spans the membrane and allows H ions to pass through.  
Calvin Cycle   Uses ATP and NADPH from light dependent reactions to produce high-energy sugars.  
Calorie   The amount of energy needed to raise the temperature of 1 gram of water, 1 degree.  
Glycolysis   A pathway that releases only a small amount of energy, unless oxygen is present, which then leads to two energy pathways.  
Cellular Respiration   The process that releases energy by breaking down glucose and other food molecules. 6O2 +C6H12O6.....6CO2 + 6H2O + Energy  
NAD+   A reactant of glycolysis; releases four high energy electrons and passes them to an electron carrier,  
Fermentation   Releases energy from food molecules by producing ATP in the absence of oxygen.  
Anaerobic Reaction   Does not require oxygen  
Aerobic Reaction   Requires oxygen  
Krebs Cycle   Second stage of cellular respiration; in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions.  
Fermentation   A reaction that releases energy from food molecules by producing ATP in the absence of oxygen.  
Alcoholic Fermentation   Anaerobic reaction that takes pyruvic acid + NADH...alcohol + CO2 + NAD+  
Lactic Acid Fermentation   pyruvic acid + NADH....lactic acid + NAD+  
Pyruvic Acid   The result of glycolysis, in which glucose is broken down into two molecules of this reactant.  
Krebs Cycle   Pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions.  
Electron Transport Chain   Converts ADP to ATP from the carriers of the Kreb cycle.
