Vocab Chapter 4

QuestionAnswer
ATP (adenosine triphosphate) high-energy molecule that contains, within its bonds, energy that a cell can use
ADP (adenosine triphosphate) low-energy molecule that can be converted into ATP
chemosynthesis process by which ATP is synthesized by using chemicals as an energy source instead of light
photosynthesis process by which energy is converted to chemical energy; produces sugar and oxygen from carbon dioxide and water
chlorophyll light-absorbing pigment molecule in photosynthetic reactions
thylakoid membrane-bound structure within chloroplasts that contains chlorophyll and other light-absorbing pigments used in the light-dependent reactions of photosynthesis
light-dependent reactions part of photosynthesis that absorbs energy from sunlight and transfers energy to the light-independent reactions
light-independent reactions part of photosynthesis that uses energy absorbed during the light-dependent reactions to synthesize carbohydrates
photosystem series of light-absorbing pigments and proteins that capture and transfer energy in the thylakoid membrane
electron transport chain series of proteins in the thylakoid and mitochondrial membranes that aid in converting ADP to ATP by transferring electrons
ATP synthase enzyme that catalyzes the reaction that adds a high energy phosphate group to ADP to form ATP
Calvin cycle process by which a photosynthetic organism uses energy to synthesize simple sugars from CO2
cellular respiration process of producing ATP by breaking down carbon-based molecules when oxygen is present
aerobic process that requires oxygen to occur
glycolysis anaerobic process in which glucose is broken down into two molecules of pyruvate and two net ATP are produced
anaerobic process that does not require oxygen to occur
Krebs cycle process during cellular respiration that breaks down a carbon molecule to produce molecules that are used in the electron transport chain
fermentation anaerobic process by which ATP is produced by glycolysis
lactic acid product of fermentation in many types of cells, including human muscle cells
