adenosine triphosphate		second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
light-dependent reactions		obtain energy form the foods they consume
anaerobic		light-absorbing colored molecule
calorie		reactions of photosynthesis in which energy form ATP and NADPH is used to build high energy compounds such as sugars
stroma		organisms that make thier own food
autotroph		reactions of photosynthesis that uses energy from light to produce ATP and NADPH
pigment		process that does not require oxygen
thylakiod		first step in releasing the energy of glucose, i which a molecule of glucose is broken into two molecules of pyruvic acid
chlorphyll		process by which plants and some other organisms use light energy to power chemical reactions that convert water and carbon dixide into oxygen and high-energy carbohydrates
heterotrophs		electron carrier involved in glycolysis
cellular respiration		region outside the thylakiod membranes in cholorplasts
ATP synthase		process by which cells release energy in the absence of oxygen
Krebs cycle		saclike body in chorloplats made of photosynthetic membranes thata contain photosystems
Calvin Cycle		one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules
glycolysis		one of the principal chemical compounds that living things use to store energy
NAD		amount of enegy required to raise the temperture of 1 gram of water by 1 Celsius degree
NADP		large protien that uses energy from H ions to bind ADP and phosphate groupo together to produce ATP
fermentation		principal pigment of plants and other photosynthetic organisms
photosynthesis		process that releases energy by breaking down food molecules in the presence of oxygen
