What different end products are produced in cyclic versus noncyclic photosynthesis?
In cyclic photosynthesis, the end product is ATP (adenosine triphosphate) only. In noncyclic photosynthesis, the end products are ATP, NADPH, and oxygen.
Compare and contrast light dependent and light independent reactions of photosynthesis.?
Light-dependent reactions occur in the thylakoid membrane and require light energy to produce ATP and NADPH. Light-independent reactions (Calvin Cycle) occur in the stroma and use ATP and NADPH to convert CO2 into glucose. Both processes are essential for photosynthesis and occur in chloroplasts.
Number of ATP produces in photosynthesis?
Technically, ATP is produced only in the light reaction, their are 18 ATP molecules formed in it. In the dark reaction, ADP is formed by the breaking of the second and third phosphate group in ATP. Though overall in photosynthesis ATP isn't produced, it is formed in the light reaction, then broken in the dark, then recycled into the light, no over all gain or loss.
What is cyclic and non cyclic?
Cyclic photophosphorylation is when the electron from the chlorophyll went through the electron transport chain and return back to the chlorophyll. Noncyclic photophosphorylation is when the electron from the chlorophyll doesn't return back but incorporated into NADPH.
In noncyclic photophosphorylation what is the ultimate acceptor of electrons that have been produced from the splitting of water?
Carbon dioxide is a noncyclic photophosphorylation and is the ultimate acceptor of electrons that have been produced from the splitting of water. A product of both cyclic and noncyclic photophosphorylation is ATP.
Where does cyclic electron transport occur?
Cyclic electron transport occurs in the thylakoid membrane of chloroplasts during the light reactions of photosynthesis. It involves the flow of electrons through the photosynthetic electron transport chain to generate ATP without the production of NADPH.
What are electron carriers used in photosynthesis?
Pigment I & II systems of cyclic and non-cyclic phosphorylation.
Which pathways in photosynthesis will produce ATP but not NADPH?
non-cyclic electron pathways
The role of p700 during the cyclic reactions is to do what?
The role of P700 during the cyclic reactions of photosynthesis is to receive electrons from plastocyanin and become reduced. This reduction allows it to transfer high-energy electrons to the electron transport chain, ultimately generating ATP.
What different end products are produced in cyclic versus noncyclic photosynthesis?
In cyclic photosynthesis, the end product is ATP (adenosine triphosphate) only. In noncyclic photosynthesis, the end products are ATP, NADPH, and oxygen.
What does non-cyclic photophosphorylation produce?
Non-cyclic photophosphorylation, which occurs in the light-dependent reactions of photosynthesis, produces ATP and NADPH. These molecules serve as energy carriers that are used in the Calvin cycle to produce sugars.
The cyclic pathways of photosynthesis produce?
The cyclic pathways of photosynthesis produce ATP (adenosine triphosphate) through the process of cyclic photophosphorylation. This pathway involves the movement of electrons through the photosystem I in a cyclic manner, leading to the formation of ATP as an energy carrier for the cell.
What is required to excite the electrons of the chlorophyll and start the cyclic and non-cyclic phosphorylation?
To excite the electrons of chlorophyll and initiate cyclic and non-cyclic photophosphorylation in photosynthesis, light energy is required. The energy from photons of light is absorbed by chlorophyll molecules in the thylakoid membranes of chloroplasts, leading to the excitation of electrons and the subsequent transfer of these electrons through the electron transport chain. This process generates ATP and NADPH, which are essential for the synthesis of carbohydrates during the light-dependent reactions of photosynthesis.
What reactions are referred to as light dependent reactions?
Cyclic and non-cyclic photophosphorylation.
What are the products of a non-cyclic electron flow?
The products of non-cyclic electron flow in photosynthesis are ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). This process occurs during the light-dependent reactions of photosynthesis and helps to generate energy-rich molecules that are used in the Calvin cycle to produce glucose.
When does non cyclic electron flow?
Non-cyclic electron flow occurs in the photosystems of plant chloroplasts during photosynthesis when electrons are transferred through both photosystem I and II to generate ATP and NADPH. This process does not involve the formation of ATP synthase or the production of ATP through chemiosmosis.
Is the light dependant reaction cyclic?
Yes, the light-dependent reaction of photosynthesis involves a cyclic flow of electrons between photosystem I and photosystem II. This cycle helps generate ATP and NADPH for the Calvin Cycle to produce glucose.
