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