15 Cards in this Set

  • Front
  • Back
alcoholic fermentation
anaerobic process in which pyruvic acid is changed to ethyl alcohol and CO2;carried out by many bacteria and fungi
photosynthesis
process by which autotrophs produce simple sugars from water and carbon dioxide using energy absorbed from sunlight by chlorophyll; oxygen is ont of the end products
ATP
adenosine triphosphate; enery storing molecule that serves as the cell's "energy currency" stored energy of gluclose is used to attach phosphate groups to ADP to form ATP
citric acid cycle
cyclic series of chemical reactions that take place during aerobic respiration; produces ATP and releases electrons
light reactions
highly complex reactions by which light energy is converted to chemical energy during photosynthesis; results in the spiltting of water and release of oxygen
Chemosynthesis
process to obtain energy and produce food from inoganic compounds used by some organisms, such as methane-producing bacteria.
anaerobic process
simple biological process that does not require oxygen
respiration
process in which cells break down molecules of food to release energy; cellular respiration can be either aerobic of anaerobic
aeroboic process
oxygen-requiring biological process
ADP
adenosine diphosphate; molecules occuring from ATP,resulting in the release of energy to do biological work.
glycolysis
anaerobic process that splits glucose, forming two molecules of pyruvic acid; also produces hydrogen ions and electons
photoysis
spiltting of water molecules during photosynthesis
Calvin cycle
set of reactions during photosynthesis in which simple sugars are formed from CO2 using ATP and hydrogen from the light reactions
electron transport chain
series of molecules along which electrons are transferred; as the electrons travel, they release energy that is stored in the bonds of ATP
lactic acid fermemtation
anaerobic process in which pyruvic acids changes to lactic acid; occurs in some bacteria, plants, and most animals; can create an oxygen acid resulting in fatigue
