What is the equation for the light-dependent reaction of photosynthesis?
The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.
What is the light-dependent equation?
The chemical formula for the reaction is 6CO2 + 6H2O + Light = (CH2O)6 + 6 O2, but there are many individual steps leading to the overall result. In the light-dependent reactions, the plant cells absorb light energy and use it to split water molecules.
What are products of the light-dependent reactions of photosynthesis?
The exergonic light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. These reactions occur in the thylakoids of the chloroplasts. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions.
What is ADP and NADP+?
In the first step ADP is converted to ATP. NADPH serves as an electron donor. ADP and NADP+ move back from the Calvin cycle, restores in the thylakoid membrane, and participate in the light-dependent reaction. NADPH and ATP are produced mainly in the light-dependent reaction.
What is light-independent in photosynthesis?
Light-independent reaction is a series of biochemical reactions in photosynthesis not requiring light to proceed, and ultimately produce organic molecules from carbon dioxide. The energy released from ATP (produced during the light reactions) drives this metabolic pathway.
What are the four reactions of the light-dependent reaction?
There are four major protein complexes in the thylakoid membrane: Photosystem II (PSII), Cytochrome b6f complex, Photosystem I (PSI), and ATP synthase. These four complexes work together to ultimately create the products ATP and NADPH.
What are the 5 steps of light dependent reactions?
Here are the basic steps:
- Light absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center.
- ATP synthesis.
- Light absorption in PSI.
- NADPH formation.
What are the 3 products made in the light dependent reaction?
Glucose, ATP and O2
What happens to NADP+ and ADP in the Calvin cycle?
ADP and NADP+ move back from the Calvin cycle, restores in the thylakoid membrane, and participate in the light-dependent reaction. Conversion of NADP+ to NADPH yields one molecule of water. At the same time, conversion of ADP to ATP yields a carbon dioxide reaction. All of these processes occur in the stroma.
