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.

How is water related to the water cycle?
Water is (of course) the main part of the water cycle. As you can see in the picture, (ps thanks to osovo.com who owns this pic) water is what flows throughout the cycle.

You can play Harry Potter game on the Nintendo Wii (WII); The Gameboy Advance (GBA); The Nintendo DS (DS or Nintendo); The Gamecube; The PlayStation I, II, III (PS, PS II, PS III); You're computer; Internet, and so forth.
How do plants create food What is the formula for photosynthesis Where does photosynthesis take place and why is it possible?
The formula for photosynthesis (abv. photos.) is: Light Energy + Co2 + H20 --------> Carbohydrate + Oxygen As a whole, photos. takes place in the chloroplasts of a plant cell. There are two main reactions that occur during photos. The light-dependent reaction and the light-independent reaction. Each reaction takes place within a different section of the chloroplasts. The Thylakoids are the sight of the light-dependent reactions. Thylakoids look like little green coins. When they are stacked, they are called grana. Light dependent reactions are very complicated. They involve two photosystems, called photosystem II and I. Each photosystem has it's own little reaction that is complicated. PS I makes ATP and PS II makes ATP + HADPH. PS II is famous for spliting H2O's into H+ and O2. The stroma is the sight of the light indepentdent reactions. Stroma is the gel-like area outside of the thylakoids. As the name suggests, these reactions don't require light. This is called the Calvin Cycle. The Calvin Cycle pretty much takes 3CO2 and changes it into 6 PGAL's + 3C.Were dose food-making in plants take place?Were dose food-making in plants take place?
What is the length in nanoseconds of one cycle of a 10 GHz computer?
A 10 GHz clock would have a period of 0.1 ns, or 100 ps (pico seconds). In practice, however, a machine cycle is several clocks, so multiply the number of clocks per cycle by 100 ps.
What do you call a final part that begins with p?
A final part can be called a post script, or as an abbreviation, a PS.

What is the difference between photosynthesis I and photosynthesis II?
Photosynthesis II or PS II (photosystem II) comes before PS I. PSII uses a pair of P680 chlorophyll a, while PSI uses a pair of P700 chlorophyll a. These systems populate the thylakoid membrane.First, light hits PS II and excites its pigment molecules and the energy bounces off the pigment molecules until it gets to the P680 chlorophyll and excites its electrons which then causes it to give off an electron to the Primary electron acceptor.Now the pair of P680 is deprived of an electron, this is where water comes nto play. An enzyme catalyzes the splitting of water to produce O2 and two electrons, these electrons supply the ones that the pair of P680 chlorophyll gave away, this enables the P680 to be able to get excited again and again without being deprived of electrons.Back to the primary acceptor, the excited electron passes from PS II to PS I via the Electron Transport chain. This produces ATP.The electron then is at the P700 pair of chlorophyll a's of PS I which excites it and it gives off that electron to another primary electron acceptor which transports its electrons via ETC as well, but the final electron acceptor is NADP+, which with the electron becomes: NADPH.
What is a photosytem?
Chloroplasts can only absorb certain wavelengths of light because of the pigments they contain. There are 2 photosystems in plants called photosystem I and II. PS I absorbs light on the wavelength of 700nm while PS II absorbs 680nm because of their utilization of chlorophyll A and B. These two frequencies are are known as the peak absorption points because they are the wavelength at which light is most strongly absorbed. Different forms of chlorophyll and other photosynthetic pigments absorb other other frequencies of light but PS I and PS II are what is used for synthesizing ATP and reducing power which plants use to grow. The visible spectrum of light is between 380-750nm for humans. Therefore PS I and II require red light to perform photosynthesis. As stated before, however, there are other photosynthetic pigments present in plants and other phototrophic species such as bacteria and algae that absorb other pigments. An example of this is the carotenoid pigment that absorbs primarily blue light as do chlorophyll A and B. Blue light contains more energy than red light but for PS I and II and plant growth both are needed.
How do you fix power stering on Nissan Micra 54 reg PS light stays on?
sometimes a temporary fix is just reading the codes from obd (obd II), and removing this. Permanent fix is to get the control box and or PS motor replaced. for the first fix you are looking for auto electrician who has a obd II diagnostic reader. I am surprised that Nissan has got away with this one
