What else can I help you with?
Where do the electrons needed by the water-splitting photosystem originate?
The electrons needed for water-splitting in the photosystem originate from the splitting of water molecules during the light-dependent reactions of photosynthesis. Water molecules are split into oxygen, protons, and electrons by the photosystem II enzyme, providing the electrons needed to drive the electron transport chain.
What effect does a dog have when head splits?
If a dog's head splits, it would likely lead to severe injuries, pain, and potential death for the dog. Such an injury would require immediate medical attention to address the trauma and prevent complications.
What animal is fleegle and drooper?
In the whacky world of the Banana Splits, Fleegle is a beagle dog, Bingo is a gorilla, Drooper is a lion and Snorky (or 'Snork' in the theme tune lyrics) is an elephant. Over hill and highway the banana buggies go, coming on to bring you the Banana Splits Show!
How many tongues do ducks have?
Snakes only have one tongue it may look like they have two as their tongues are forked. The tongue splits at the end making it appear it has two tongues.
Why do amphibians and reptiles tolerate mixing of blood in the heart?
because the septum splits and allows it to pass through
What splits water?
which photosystem (p680or P700) splits water? P680
Which is a role of photosystem 11 in the light reactions?
Photosystem II plays a role in absorbing light energy and initiating the process of photosynthesis by passing electrons through the electron transport chain. It also splits water molecules to release oxygen as a byproduct.
During the dark reactions the reaction center splits water?
During the dark reactions (Calvin cycle) of photosynthesis, water is not split. Instead, the dark reactions use the products of the light reactions (ATP and NADPH) to convert carbon dioxide into glucose through a series of enzyme-controlled reactions. The splitting of water occurs in the light reactions at Photosystem II to generate oxygen, electrons, and protons.
Why do plants give off 02 as a product of photosynthesis?
Because of photolysis. An enzyme splits water and electrons for photosystem II, hydrogen ions and oxygen that diffuses out of the leaves is the result here.
What fills the electron hole in photsystem 1 and 2?
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
What happens to electrons when pigments in photosystem absorb lights?
Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water. For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.
Where do the electrons needed by the water-splitting photosystem originate?
The electrons needed for water-splitting in the photosystem originate from the splitting of water molecules during the light-dependent reactions of photosynthesis. Water molecules are split into oxygen, protons, and electrons by the photosystem II enzyme, providing the electrons needed to drive the electron transport chain.
What Photosystem is older in terms of evolutionary history?
Photosystem II is older in terms of evolutionary history compared to Photosystem I. Photosystem II is thought to have evolved before Photosystem I as it evolved to oxidize water in order to provide electrons for the electron transport chain, which Photosystem I then uses to reduce NADP+ to NADPH.
The chlorophyll known as P680 has its electron holes filled by electrons from what a. photosystem I. b. photosystem II c. water d. NADPH e. accessory pigments?
Oxidized P680 receives its electrons, from water oxidization. (2H2O --> O2 + 4H+ + 4e-).
Where do electrons get their in photosystem I?
From energy in photons
Which photosystem is used first in photosynthesis?
Photosystem 2 happens in photosynthesis before photosystem 1. However they are numbered in order of how they were discovered. Photosystem 1 was discovered before photosystem 2. In photosynthesis the order of them is 2 then 1. meaning that photosystem 1 was discovered 1st but photosystem 2 happens 1st in photosynthesis
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 during the process of photolysis. These electrons are used to replace the ones lost by chlorophyll when it absorbs light energy, allowing the photosystem to continue absorbing light and generating ATP and NADPH for the Calvin cycle.
