How are photosystem I and II similar and different?
Photosystem I is very receptive to light waves at the 700 nm wavelength. In comparison, photosystem II is very receptive to light wavelengths of around 680 nm. Both photosystem I and II are necessary in most plants to produce the energy they need from the sun.
What do both photosystem 1 and 2 have in common?
There are two types of photosystems: photosystem I (PSI) and photosystem II (PSII). Both photosystems contain many pigments that help collect light energy, as well as a special pair of chlorophyll molecules found at the core (reaction center) of the photosystem.
How does photosystem 1 and 2 work together?
Understanding Pigments Chlorophylls and carotenoids are the two major classes of photosynthetic pigments found in plants and algae; each class has multiple types of pigment molecules. There are five major chlorophylls: a, b, c and d, along with a related molecule found in prokaryotes called bacteriochlorophyll.
What is the difference between the roles of photosystem 1 and 2 in photosynthesis quizlet?
Photosystem I produces NADPH, which is similar in function to the NADH and FADH2 produced by the citric acid cycle. NADPH is an electron carrier that can donate electrons to other compounds and thus reduce them. Photosystem II produces a proton gradient that drives the synthesis of ATP.
What is ps1 and ps2 in photosynthesis?
Difference # Photosystem II (PS II): Photosystem II (PS II) is involved only in non-cyclic photophosphorylation. 2. Photosystem II (PS II) donates electrons to photosystem I where NADP+ is reduced. 3. This system is responsible for the photolysis of water and involves the evolution of molecular oxygen.
Who discovered photosystem 1 and 2?
Robert Emerson discovered pigment system-I (PS-I) and pigment system-II (PS-II).
