Respiration Questions And Answers
thylakoid membrane the photosynthetic membrane within a chloroplast that contains
light-gathering pigments molecules and electron transport chains, this is where the light
dependant reaction occurs
thylakoid lumen the fluid-filled space inside a thylakoid
ATP adenosine triphosphate, a molecule containing three high-energy phosphate bonds
that acts as the primary energy-transferring molecule in living organisms
ADP adenosine diphosphate, a molecule containing two high-energy phosphate bonds that
may be formed by breaking one phosphate bond in ATP
NADP+ a compound that accepts one hydrogen ion and two electrons, is an electron
acceptor
NADPH a compound which donates one hydrogen ion and two electrons, is an electron
donor
, Biology 20: Photosynthesis and Cellular
Respiration Questions And Answers
light-dependent reaction the first set of reactions of photosynthesis in which light energy
excites electrons in chlorophyll molecules, powers chemiosmotic ATP synthesis, and results in
the reduction of NADP+ to NADPH
carbon fixation the process of incorporating carbon dioxide into carbohydrate molecules
Calvin cycle a cyclic set of reactions occurring in the stroma of chloroplasts that fixes the
carbon of a carbon dioxide into carbohydrate molecules and recycles enzyes
light-independant reactions the second set of reactions in photosynthesis (the Calvin
cycle); also known as dark reactions because they do not require solar energy. Uses the energy
stored in ATP and electrons from NADH to crease glucose
photosystem a cluster of photosynthetic pigments embedded in a thylakoid membrane of a
chloroplast that absorbs light energy
electron transport chain a series of progressively stronger electron acceptors; each time an
electron is transferred, energy is released
