Does PS1 or PS2 come first?

The PlayStation's success led to a line of successors, beginning with the PlayStation 2 in 2000. In the same year, Sony released a smaller and cheaper model, the PS One.

Does PS2 come before PS1?

The PlayStation 2 (PS2) is Sony's second video game console. It was released in March of 2000. The one before this was PlayStation (or PS1).

What accepts the electron after it passes through the second electron transport complex?

After complex II in the electron transport system, electrons are passed to ubiquinone and then further complex III, i.e. cytochrome bc1.

What is the function of the electron transport chain of photosystem II?

The electron transport chain moves protons across the thylakoid membrane into the lumen. At the same time, splitting of water adds protons to the lumen, and reduction of NADPH removes protons from the stroma.

What is the electron donor for photosynthesis?

Oxygenic photosynthesis requires water, which acts as an electron donor molecule. The reactions which involve the trapping of sunlight are known as "light reactions", and result in the production of NADPH, adenosine triphosphate, and molecular oxygen.

What is the electron donor for PSII?

The Primary Electron Donor of Photosystem II of the Cyanobacterium Acaryochloris marina Is a Chlorophyll d and the Water Oxidation Is Driven by a Chlorophyll a/Chlorophyll d Heterodimer.

What is the final electron acceptor in photosystem 1 and 2?

The light reactions of photosynthesis, which take place in photosystems II and I. Light energy is harvested and used to power the transfer of electrons among a series of electron donors and acceptors. The final electron acceptor is NADP+, which is reduced to NADPH.

What is the difference between ps1 and ps2?

The key difference between both the photosystems – Photosystem I and photosystem II is that PS I tends to absorb light of longer wavelengths > 680nm, whereas PS II absorbs light of shorter wavelengths <680 nm.

Why does photosystem 2 come first?

Their names, however, are based on the time of their discovery. Photosystem I was discovered and named first, followed by photosystem II, which was discovered second. Another reason why photosystem II goes first is that photosystem I depend on the electron that is liberated by photosystem II.

Does photosystem II come first or second in the electron transport chain?

Photosystem I vs. photosystem II

PSII comes first in the path of electron flow, but it is named as second because it was discovered after PSI.

How are electrons moved from photosystem II to photosystem I in photosynthesis?

From photosystem II, electrons are carried by plastocyanin (a peripheral membrane protein) to photosystem I, where the absorption of additional photons again generates high-energy electrons. Photosystem I, however, does not act as a proton pump; instead, it uses these high-energy electrons to reduce NADP⁺ to NADPH.

What are the steps of electron transport?

In what order do electrons move through the electron transport chain?

The electrons must travel through special proteins stuck in the thylakoid membrane. They go through the first special protein (the photosystem II protein) and down the electron transport chain. Then they pass through a second special protein (photosystem I protein).

What came out before PS1?

First generation (1972–1980)

The Magnavox Odyssey was the first video game console, released in 1972.

What console came after the PS1?

The original PlayStation continued production until March 2005, when it was eclipsed by the next generation of 64-bit consoles, including Sony's own PlayStation 2 (PS2; introduced in the early 2000s).

What are PS1 and PS2 associated with?

PS I and PS II are the two photosystems which drive the light reaction of photosynthesis. The first stage of the light reaction occurs in PS II whereas the final stage of the light reaction occurs in PS I. Each of the two photosystems are made up of a collection of proteins and pigments.

Does photosystem 2 come first?

Photosystem II is the first link in the chain of photosynthesis. It captures photons and uses the energy to extract electrons from water molecules.

Does photosystem 1 occur before photosystem 2?

Photosystem I occurs before photosystem II during the light reactions. a collection of pigments that trap solar energy and focus it on reaction centers, releasing high-energy electrons.

Is photosystem 1 first?

History. This photosystem is known as PSI because it was discovered before Photosystem II, although future experiments showed that Photosystem II is actually the first enzyme of the photosynthetic electron transport chain.

Do all PS2 play PS1 games?

The PlayStation 2 was designed to be backward compatible with PlayStation games. However, not all PlayStation games work on the PlayStation 2.

Does PS2 have a PS1 chip?

In addition, the console can play audio CDs and DVD movies, and is backwards compatible with original PlayStation games. This is accomplished through the inclusion of the original PlayStation's CPU which also serves as the PS2's I/O processor, clocked at 36.864 MHz in PS2 mode.

Why do some PS1 games have 2 discs?

Despite the huge increase in storage though, some developers still needed more, which led to numerous PS1 games being released on multiple discs. In North America alone, there were more than 50 such titles, with each one coming in a special multi-disc jewel case.

What is the correct order of the steps of the Calvin cycle?

So, the correct answer is 'Carboxylation → reduction →Regeneration.

What replaces electrons in photosystem 2?

The two electrons lost from photosystem II are replaced by the splitting of water molecules. Water splitting also releases hydrogen ions into the lumen.

What replaces electrons in photosystem 1?

Photosynthetic eukaryotes and cyanobacteria have two photosystems – Photosystem II and Photosystem I. Light energy causes the excitation and loss of an electron from a PSII reaction center chlorophyll (P680). Water is oxidized to replace the lost electron, generating H⁺ ions and oxygen (O^-2) ions.
