Photosynthesis Flashcards
Reduced
GAINS one or more electrons
Oxidized
LOSES one or more electrons
NAD
Nicotinamide Adenine Dinucleotide
NADPH
Nicotinamide Adenine Dinucleotide Phosphate
NADP+
Nicotinamide Adenine Dinucleotide Reductase
ADP
Adenosine Diphosphate
ATP
Adenosine Triphosphate
What is the energy currency of a plant cell
Adenosine Triphosphate/ATP
Photon
A particle representing a quantum of light or other magnetic radiation. It also carries energy proportional to the radiational system
(Photons that a specific pigment does not absorb are reflected by the pigment)
Photosystem
a biochemical mechanism in plants by which chlorophyll absorbs light energy for photosynthesis. There are two such mechanisms ( photosystems I and II ) involving different chlorophyll-protein complexes.
Chlorophyll A
Reflects a green light
Chlorophyll B
Reflects a yellow-green light
Absorption in 626 nanometers and 392 nm
An accessory pigment
Chlorophyll C
Reflects a Blue-Green light
Absorption in 447-57 nm
Also an accessory pigment
Chlorophyll D
Absorbs far-red light at 710 nm wavelength
Pigments
Molecules that absorbs protons of CERTAIN wavelengths only
A spectrum that the human eye can view
Visible light spectrum
Major sites of photosynthesis
Chloroplasts
What is photosynthesis
the process in which light energy is converted to chemical energy in the form of sugars.
The photosynthesis equation
6CO2 + 6H2O → C6H12O6 + 6O2.
What is a light-dependent reaction
a photochemical reaction taking place in the thylakoid membranes of chloroplasts, where light energy is transformed into (ATP) and (NADPH).
