ADP- adenosine diphosphate
molecule formed from the breaking off of a phosphate group for ATP, results in a release of energy that is used for biological reaction
Chemical reactions that require the presence of oxygen
ATP- adenosine triphosphate
energy-storing molecule in cells composed fo an adenosine molecule, a ribose sugar and three phosphate groups; energy is stored in the molecule's chemical bonds and can be used quickly and easily by cells
reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars
the starches and sugars present in foods
a heavy odorless colorless gas formed during respiration and by the decomposition of organic substances
the metabolic processes whereby certain organisms obtain energy from organic moelcules
green pigment in plants that absorbs light energy used to carry out photosynthesis
organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
electron transport chain
a series of molecules, found in the inner membranes of mitochondria and chloroplasts, through which electrons pass in a process that causes protons to build up on one side of the membrane
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. When its level is low, we feel hunger.
a metabolic process that breaks down carbohydrates and sugars through a series of reactions to either pyruvic acid or lactic acid and release energy for the body in the form of ATP
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
reactions of photosynthesis that use energy from light to produce ATP and NADPH
the cells powerhouse, turning food into energy, it's where cellular respiration takes place. (Harvesting chemical energy).
one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules
process by which plants use the sun's energy to convert water and carbon dioxide into sugars
the elements or compounds produced by a chemical reaction
the elements or compounds that enter into a chemical reaction
The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water.
A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.
