i dont know.....hahaha
What else can I help you with?
What reactions are referred to as light dependent reactions?
Cyclic and non-cyclic photophosphorylation.
How is light reaction of photosynthesis started?
Absorbtion of light by photosystems in cyclic and non-cyclic photophosphorylation.
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.
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.
A product of cyclic photophosphorylation is?
The product of cyclic photophosphorylation is ATP. In this process, light energy is used to generate ATP from ADP and inorganic phosphate within the thylakoid membrane of chloroplasts.
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.
Do plants use cyclic photophosphorylation?
Yes, plants use cyclic photophosphorylation to generate ATP during photosynthesis. This process occurs in the thylakoid membrane of chloroplasts and helps maintain ATP levels when NADPH production is in excess.
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 is netgain light reaction?
The net gain in the light reaction of photosynthesis is the production of ATP and NADPH molecules, which are then used in the Calvin cycle to produce glucose. These molecules carry the energy captured from sunlight and convert it into chemical energy.
What is the difference between cycle and noncycle photophosphorylation?
Cycle photophosphorylation occurs in cyclic electron flow, where electrons are recycled to produce ATP but not NADPH. Noncyclic photophosphorylation involves both photosystems I and II to produce both ATP and NADPH using electrons extracted from water.
Which event occurs last in the non cyclic pathway of ATP formation?
The last event in the non-cyclic pathway of ATP formation is the reduction of NADP+ to NADPH during the light-dependent reactions of photosynthesis. This process occurs after the formation of ATP through photophosphorylation, and provides reducing power to drive the Calvin cycle for the synthesis of carbohydrates.
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.
