A small molecule used in cells as a coenzyme
Adenosine Triphosphate (ATP)
Process used by plants and other autotrophs to capture light energy 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
Principal pigment of plants and other photosynthetic organisms
Chlorophyll
Organelle found in cells of plants and some other organisms that capture the energy from sunlight and converts it into chemical energy
Chloroplast
Set of reactions on photosynthesis that use energy from light to produce ATP and NADPH
Light-dependent reaction
Set of reactions in photosynthesis that do not require light
Light-independent reactions
First set of reactions in cellular respiration in which a molecule of glucose is broken into two mollecules of pyruvic 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
Anaerobic
Process that does require oxygen
Aerobic
the sequence of reactions by which most living cells generate energy during the process of aerobic respiration
Krebs Cycle
