6H20 + 6CO2 --> C6H12O6 + 6O2
Location of Photosynthesis
Reactants of Photosynthesis
6H20 + 6CO2
Products of Photosynthesis
C6H12O6 + 6O2
Chemicals that absorb light energy and use it to carry out photosynthesis. Contained in thylakoid membranes in chloroplast. Examples are chlorophyll a, chlorophyll b, carotenoids, xanthophylls, and phycobilins.
2 Reactions of Photosynthesis
Light Dependent Reaction
Light Independent Reaction (Calvin Cycle)
Requirements for Light Dependent Reaction
ATP (adenosine triphosphate)
Main energy source that cells use for most of their work.
Products of Light Dependent Reaction
ATP (from ADP)
NADPH (from NADP+)
Location of Light Dependent Reaction
Thylakoid Membrane (inside chloroplast)
1st Electron Transport Chain
Series of chemical reactions in the thylakoid membrane electrons are passed along with the release of energy, used to construct ATP
2nd Electron Transport Chain
High-energy electrons are passed to NADP+, creating. NADPH, a high-energy electron carrier.
An electron carrier involved in photosynthesis. Light drives electrons from chlorophyll to NADP+, forming NADPH, which provides the high-energy electrons for the reduction of carbon dioxide to sugar in the Calvin cycle.
In the thylakoid membranes of a chloroplast during light-dependant reactions, two molecules of water are split to form oxygen, hydrogen ions, and electrons.
The process in which carbon dioxide, ATP, and NADPH are turned into glucose, ADP, and NADP+. Also called the "Light Independent Reaction."
The rate at which plants take in carbon dioxide, water, and the energy from sunlight to produce sugar.
Light Intensity vs Photosynthetic Rate
Rate of photosynthesis increases with the light intensity up to a certain amount
Carbon Dioxide Level vs Photosynthetic Rate
Increased levels will stimulate photosynthesis and then it will level off.
Temperature vs Photosynthetic Rate
Color of Light vs Photosynthetic Rate
Different pigments impact rate of photosynthesis. Generally, green light results in the lowest photosynthetic rate.
