Questions And
Answers
Photon - answer:-A packet of light.
Chlorophyll - answer:-The light-absorbing green-coloured pigment that begins the
process of photosynthesis.
Chloroplast - answer:-A membrane-bound organelle in green plant and algal cells that
carries out photosynthesis.
Stroma - answer:-The protein-rich semiliquid material in the interior of a chloroplast.
Thylakoid - answer:-A disk-shaped sac in the stroma of a chloroplast.
Grana - answer:-Stacks of tylakoids.
Lamellae - answer:-Groups of unstacked thylakoids between grana.
Thylakoid Membrane - answer:-The photosynthetic membrane within a chloroplast that
contains light gathering pigment molecules and electron transport chains.
Thylakoid Lumen - answer:-A fluid-filled interior space enclosed by the thylakoid
membrane.
ATP - answer:-A molecule containing three high energy phosphate bonds that acts as
the primary energy-transferring molecule in a living organism.
ADP - answer:-A molecule containing two high-energy phosphate bonds that may be
formed by breaking one of the phosphate bonds in ATP.
NADP+ - answer:-A compound that accepts one hydrogen atom and two electrons
forming NADPH; it is an electron acceptor.
NADPH - answer:-A compound that donates one hydrogen aton and two electrons to
another molecule, to reform NADP+; it is an electron donor.
Light-dependent reactions - answer:-reactions of photosynthesis that use energy from
light to produce ATP and NADPH
Carbon Fixation - answer:-The process of incorporation CO2 into carbohydrate
molecules.
