(ADP) a substance involved in energy metabolism formed by the breakdown of adenosine triphosphate
energy actually used in cell processes, better known as ATP
process that does not require oxygen
reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars
energy rich organic compounds made up of the elements carbon hydrogen and oxygen
a heavy odorless colorless gas formed during respiration and by the decomposition of organic substances
the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
green pigment in plants that absorbs light energy used to carry out photosynthesis
a structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food
electron transport chain
A sequence of electron carrier molecules (membrane proteins) that shuttle electrons during the redox reactions that release energy used to make ATP.
a chemical phenomenon in which an organic molecule splits into simpler substances
the form of sugar that circulates in the blood and provides the major source of energy for body tissues
first step in releasing the energy of glucose, in which a molecule of glucose is broken into two molecules of pyruvic acid
a stack of thylakoids within a chloroplast
second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions User-contributed
