The oxygen released into the air as a product of photosynthesis comea from what?
When oxygen is released as a result of photosynthesis, it is a by product of what?reducing NADP+chemiosmosisthe electron transfer system of photosystem Isplitting the water moleculesthe electron transfer system of photosystem IIsplitting the water molecules
Where do the supply of electrons come from in photosynthesis?
The supply of electrons in photosynthesis comes from water molecules. This process, known as photolysis, occurs in the light-dependent reactions of photosynthesis. Water molecules are broken down into oxygen, protons, and electrons, with the electrons being used to replenish the electrons lost in the photosystem II reaction center.
Which gas does photosynthesis produce?
Photosynthesis produces oxygen gas (O2) as a byproduct. During the process, plants and other photosynthetic organisms take in carbon dioxide and water, and in the presence of sunlight, convert these compounds into glucose and oxygen.
How are photosynthesis 1 and photosynthesis 2 similar?
Did you mean Photysystem I and Photosystem II. They both are overall identical except that Photosystem I is actually a later part of the process of Photosynthesis than Photosystem II, its only called Photosystem I because it was discovered first. Photosynthesis starts when light excites Photosystem II causing it to break up H20 that comes from the roots into H2 and 02. (If you are wondering why oxygen becomes two molecules when in H20 there is only one molecule of it, that is because it cannot exist as one molecule stably therefore it bonds with another oxygen from another break down almost instantly.) Then Photosystem II sends electrons across the electron transport pathway (along the membrane of the Thylakoid in between the two photosystems) to Photosystem I which then uses them to convert NaDP+ into NaDPH by adding a phosphate group from outside the Thylakoid. Thats pretty much what each Photosystem does and both are located inside the Thylakoid membrane.
Which protein complex in the electron transport chain after photosystem 2 produces ATP?
The protein complex in the electron transport chain after photosystem II that produces ATP is ATP synthase. This enzyme is responsible for converting the energy stored in the proton gradient into ATP through a process known as oxidative phosphorylation.
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
What photosystem splits water?
which photosystem (p680or P700) splits water? P680
Where does splitting of water and oxygen happen?
The splitting of water and oxygen happens in the chloroplasts of plant cells during the light-dependent reactions of photosynthesis. This process, known as photolysis, is catalyzed by the enzyme complex photosystem II.
The oxygen released into the air as a product of photosynthesis comea from what?
When oxygen is released as a result of photosynthesis, it is a by product of what?reducing NADP+chemiosmosisthe electron transfer system of photosystem Isplitting the water moleculesthe electron transfer system of photosystem IIsplitting the water molecules
Which process requires electrons that are obtained by the splitting of water A cyclic photophosphorylation B noncyclic photophosphorylation C Photorespiration?
B noncyclic photophosphorylation requires electrons that are obtained by the splitting of water. The process involves the flow of electrons through both photosystem I and photosystem II to generate ATP and NADPH for the light-independent reactions of photosynthesis.
Is photosynthesis a system?
Photosynthesis is not a system. It is a process in plants. It is very important process.Photosynthesis is a process of making sugars from CO2 and water by using light energy. Photosystem I and photosystem II are involved in this process to transfer electrons across the membrane. Photosynthesis occurs in plants algae and certain bacteria.
Which is a reactant for the reaction that is powered by sun hitting photosystem II?
Water is the reactant for the reaction powered by the sun hitting photosystem II. This reaction leads to the splitting of water molecules to release oxygen, protons, and electrons in the process of photosynthesis.
Where does oxygen gas come from in photosynthesis?
The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.
What is the photosystem II of photosynthesis?
Splitting H2O
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.
Which complex or enzyme of photosynthesis consumes h2o?
The complex known as Photosystem II in the thylakoid membrane of chloroplasts is responsible for splitting water (H2O) into oxygen, protons (H+), and electrons during the light-dependent reactions of photosynthesis. This process provides the electrons needed to generate ATP and NADPH for use in the Calvin cycle.
The splitting of water during photosynthesis is called?
Photolysis is the splitting of water during photosynthesis. Photosynthesis is the process which results in the conversion of light energy into chemical energy.
