The simplest look of photosynthesis will show that there are two photosystems. Photosystem II, P680, is important in initiating photosynthesis by exciting electrons to move down the electron transport chain. 680 nm is the optimal wavelength of light for this photosystem. Photosystem I, P700, transfers electrons to ferrodoxin which transfers electrons to the ferrodoxin NADP+ reductase; the NADPH formed here will be used in the Calvin cycle. 700 nm is the optimal wavelength of light for which this photosystem is most active.
What else can I help you with?
Where do the hydrogen ions for the photosystems of the light-dependent reactions originate?
The hydrogen ions for the photosystems of the light-dependent reactions originate from water molecules during the process of photosynthesis.
What do you call the clusters of chlorophyll molecules that capture light energy?
They are called photosystems. Photosystems are groups of chlorophyll molecules and associated proteins that work together to absorb and transfer light energy during the process of photosynthesis.
Role of pigments and photosystems in the capture of light energy?
Pigments, like chlorophyll, absorb light energy and transfer it to photosystems within chloroplasts. Photosystems are protein complexes that contain chlorophyll and other pigments, which facilitate the conversion of light energy into chemical energy through photosynthesis. Together, pigments and photosystems play a crucial role in capturing and converting light energy for use in the synthesis of ATP and NADPH during photosynthesis.
During photosynthesis what chemical reaction gives off heat?
During photosynthesis, no chemical reaction gives off heat. Photosynthesis is an endothermic process, meaning it requires energy in the form of sunlight to convert carbon dioxide and water into glucose and oxygen.
Is the beginning of photosynthesis pigments in photosystem absorb light?
Yes, that is correct. The light energy excites electrons in photosystems and these electrons enter the electron transport chain to make ATP. These electrons eventually end up in NADPH and photosystems are replenished with electrons obtained from splitting water.

Do Plants utilize solar energy during photosynthesis.?
Plants have to utilize solar energy during photosynthesis because it is needed to create the chemical reaction. This reaction produces glucose and oxygen.
Why are the product of the light reaction of photosynthesis important?
They are used to produce sugar during the dark reaction
Is the beginning of photosynthesis pigments in photosystem absorb light?
Yes, that is correct. The light energy excites electrons in photosystems and these electrons enter the electron transport chain to make ATP. These electrons eventually end up in NADPH and photosystems are replenished with electrons obtained from splitting water.
Is photosynthesis an energy storing reaction?
During photosynthesis, glucose is manufactured from CO2 and water. This glucose is stored in the chloroplasts as starch grains, hence the name 'energy storage reaction' for describing photosynthesis.
What reaction during photosynthesis is light is light-independent?
ATP and NADPH
What two products made during the photosynthesis reaction?
oxyen and water
