compound used cells to store and release energy
adenosine triphosphate
process used by plants and other autotrophs to capture light and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches
photosynthesis
light absorbing molecule used by plants to gather the sun's energy
pigment
principle pigment of plants and other photosynthetic organisms
chlorophyll
organelle found in cells of plants and some other organisms that captures the energy from the sunlight and converts it into chemical energy
chloroplast
set of reactions in photosynthesis that do not require light; energy from ATP and NADPH is used to build high-energy compounds such as sugars; also called the calvin cycle
light independant reaction
set of reactions in photosynthesis that use energy from light to produce ATP and NADPH
light dependant reaction
first set of reactions in cellular respirations in which a moleule of glucose is broken into two molecules of pyrvic acid
glycolysis
process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
cellular respiration
process by which cells release energy in the absence of oxygen
fermentation
process that does not require oxygen
anderobic
process that requires oxygen
aerobic
second stage of cellular respiration in which pyruvic acid is broken into carbon dioxide in a series of energy-extracting reactions
krebs cycle
