Terms in this set (32)
Organisms that use light as a source of energy to synthesize organic substances.
The major sites of photosynthesis in most plants.
Green pigment located within the chloroplasts.
Spongy tissue in the interior of the leaf where most chloroplasts are found.
Microscopic pores in the leaf which lets CO2 in and O2 out. Also where water is lost.
Bundles of xylem and phloem.
Stack of thylakoids.
Fluid inside the chloroplast where the Calvin Cycle happens.
Flattened membranes in the chloroplast where the light reactions take place.
Equation of photosynthesis.
Part of photosynthesis that involves light. ATP and NADPH are produced. Takes place on the thylakoid membrane.
Molecules that absorb, reflect, or transmit light.
A cluster of pigments embedded into a thylakoid membrane.
Accepts electrons and becomes reduced.
Donates electrons and becomes oxidized.
Substance that supplies electrons for the light reactions of photosynthesis.
Photosystem 2 performs photolysis to provide electrons for the electron transport chain that drives a chemiosmotic gradient that produces ATP.
Only Photosystem 1 works. ATP is made, no oxygen is produced, no water is split, no NADPH is made.
In the thylakoid membranes of a chloroplast during light-dependant reactions, two molecules of water are split to form oxygen, hydrogen ions, and electrons.
process of adding a phosphate group
the initial incorporation of carbon into organic compounds
Carbon fixation process in photosynthesis. Forms sugar and other organic compounds.
a graph plotting a pigment light light absorption
a profile of the relative performance of the different wavelengths in photosynthesis.
only pigment that can participate directly in the light reactions
Accessory pigments that broaden the spectrum of colors that can drive photosynthesis.
reaction center chlorophyll in the photosystem II.
reaction center cholophyll in the photosystem I
the location of the first light driven chemical reaction of photosynthesis.
primary electron acceptor
Specialized molecule that traps a high energy electron before it can return to ground state in the chlorophyll.
process by which a Hydrogen pump pumps protons into the thylakoid membrane. H+ passively flows through the ATP synthase which leads to the creation of ATP
the most abundant protein on earth. Performs Carbon Fixation in the Calvin Cycle.
