Chapter 14 Vocab Flashcards
the incorporation of carbon from atmospheric CO2 into the carbon in organic molecules
carbon fixation
a group of molecules in the inner membrane of a mitochondrion that synthesize ATP
electron transport chain
a protein complex that produces ATP
ATP synthase
the conversion by certain soil microorganisms, of atmospheric nitrogen into compounds that plants and other organisms can assimilate
nitrogen fixation
the light-harvesting unit in photosynthesis, located on the thylakoid membrane of the chloroplast
photosystem
the inner-most compartment of a mitochondrion
matrix
the fluid of the chloroplast surrounding the thylakoid membrane
stroma
an organelle in eukaryotic cells that serves as the site of cellular respiration
mitochondria
the conversion of light energy to chemical energy stored in glucose or other organic molecules
photosynthesis
a green pigment located within the chloroplast of plants
chlorophyll
an iron-containing protein, a component of electron transport chains in mitochondria and chloroplast
cytochrome (C)
a mobile electron carrier found in the respiratory and photosynthetic electron-transport chains
quinone
a chemical reaction involving the transfer of one or more electrons from one reactant to another
redox reaction
the ability of membranes to harness the energy stored in the H+ gradient to drive ATP synthesis
chemiosmotic coupling
the production of ATP using energy derived from the redox reactions of the electron transport chain
oxidative phosphorylation
