What two types of reactions occur during photosynthesis?
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
What is the role of water in the light reactions of photosynthesis?
Photosynthesis splits water to liberate O2 and fixes CO2 into sugar Water is split to have it's electrons replace the excited electron of chlorophyll the enters photosystem II.
How do photosystem 1 and 2 allow the calvin cycle to work?
No. Photosystems I and II are where light-dependent reactions occur, while the Calvin Cycle is where light-independent reactions occur. Photosynthesis begins with Photosystem II, then Photosystem I, then the products from there go to the Calvin Cycle. (yes photosystem II comes before photosystem I)
What are the light dependent reactions of photosynthesis also called?
Xeroderma Pigmentosum. this is a rare pigmentary and atrophic autosomal recessive disease in which extreme cutaneous sensitivity to ultraviolet light results from an enzyme deficiancy in the repair of DNA damaged by ultraviolet light. it begins in childhood, with early development of excessive freckling, telangiectases, keratomas, papillomas, and malignancies in sun-exposed skin, severe opthalmologic abnormalities, and, in some cases, neurological disorders.
Compare and contrast light dependent and light independent reactions of photosynthesis.?
Light dependent reactions : The first stage of the photosynthetic system is the light-dependent reaction, which converts solar energy into chemical energy. The light dependent reaction produces oxygen gas and converts ADP and NADP+ into the energy carriers ATP and NADPH. In plants, light dependent reactions occur in the thylakoid membranes of the chloroplasts and use light energy to synthesize ATP and NADPH. The light dependent reaction has two forms; cyclic and non-cyclic reaction. In the non-cyclic reaction, the photons are captured in the light-harvesting antenna complexes of photosystem II by chlorophyll and other accessory pigments.The cyclic reaction takes place only at photosystem I. Once the electron is displaced from the photosystem, the electron is passed down the electron acceptor molecules and returns back to photosystem I, from where it was emitted; hence the name cyclic reaction. Light-independent reaction : In photosynthesis, the light-independent reactions, also somewhat misleadingly called the dark reactions (they don't require darkness, but they do require the products of the light reactions), are chemical reactions that convert carbon dioxide and other compounds into glucose. It occurs in the stroma, the fluid filled area of a chloroplast outside of the thylakoid membranes. These reactions, unlike the light-dependent reactions, do not need light to occur; hence the term dark reactions. These reactions take the products of the light-dependent reactions and perform further chemical processes on them. There are two light-independent reactions: carbon fixation and the Calvin-Benson cycle.
Water participates directly in the light reactions of photosynthesis by?
Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II. Photosystem I and photosystem II both contain chlorophyll as molecules.
How does water participates directly in the light reactions of photosynthesis?
donating electrons to photosystem II

What is the role of water in the light reactions of photosynthesis?
Photosynthesis splits water to liberate O2 and fixes CO2 into sugar Water is split to have it's electrons replace the excited electron of chlorophyll the enters photosystem II.
Which role is of photosystem ii in the light reactions?
Splitting H2O (Apex)
What is the first process in the light dependent reactions of photosynthesis?
Excitation of electrons in photosystem II.
How do photosystem 1 and 2 allow the calvin cycle to work?
No. Photosystems I and II are where light-dependent reactions occur, while the Calvin Cycle is where light-independent reactions occur. Photosynthesis begins with Photosystem II, then Photosystem I, then the products from there go to the Calvin Cycle. (yes photosystem II comes before photosystem I)
Are PS I and PS II part of the Calvin cycle?
No, PS I and PS II are part of the first stage of photosynthesis, the light reactions. The Calvin cycle is the second stage of photosynthesis and does utilize the photosystems.
What is the waters role in the light reaction of photosynthesis?
Water is split to have its electrons replace the excited electron of chlorophyll, then enters photosystem II.
What is waters role in the light reaction of photosynthesis?

What is photosytem I and II?
Photosystem I and Photosystem II are two protein-based complexes found in the thylakoid membrane of chloroplasts in plants, algae, and cyanobacteria. They are involved in the process of photosynthesis, capturing and converting light energy into chemical energy. Photosystem II functions first in the light reactions of photosynthesis, while Photosystem I follows to further harness light energy and produce ATP and NADPH, which are vital for the synthesis of sugars.
