What does PC do in photosynthesis?
In the process, energy is provided to produce a proton gradient across the membrane which can be used for the ADP to ATP conversion. The electrons are returned by plastocyanin (Pc) to the P700 pigment in the reaction center to complete the cycle.
What does PC stand for in electron transport chain?
PC, short for plastocyanin, is a copper-containing compound in the electron transport chain that accepts the pair of electrons from the cytochrome b6f complex.
What is Z scheme explain with diagram?
The Z-scheme is an energy diagram for electron transfer in the “light reactions” of plant photosynthesis. It applies equally well to photosynthesis by algae and cyanobacteria. The vertical energy scale shows each molecule’s ability to transfer an electron to (i.e., to reduce) the next one from left to right.
How does cyclic electron transport work?
In cyclic electron flow (CEF), electrons are recycled around photosystem I. As a result, a transthylakoid proton gradient (ΔpH) is generated, leading to the production of ATP without concomitant production of NADPH, thus increasing the ATP/NADPH ratio within the chloroplast.
How does NADP+ become Nadph?
In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH.
What is PQ called?
Plastoquinone (PQ) is an isoprenoid quinone molecule involved in the electron transport chain in the light-dependent reactions of photosynthesis. The most common form of plastoquinone, known as PQ-A or PQ-9, is a 2,3-dimethyl-1,4-benzoquinone molecule with a side chain of nine isoprenyl units.
What is the final electron acceptor in photosynthesis?
NADP
The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product. In anoxygenic photosynthesis various electron donors are used.
Why Z scheme is called so?
– The energy splits the water and extracts the electrons from it, these electrons are formed in the photosystem II move from that system to cytochrome b6 and to Photosystem I. It links the two photosystems in form Z. Hence, the correct answer is option (A).
What is Z scheme BYJU’s?
Z-scheme of the light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. It is concerned with electron transfer along with the synthesis of ATP and NADPH. Suggest corrections.
How does cyclic electron flow support photosynthesis?
Photosynthesis provides at least two routes through which light energy can be used to generate a proton gradient across the thylakoid membrane of chloroplasts, which is subsequently used to synthesize ATP. Such cyclic flow generates ΔpH and thus ATP without the accumulation of reduced species.
Does cyclic electron flow use light?
The light reactions in photosynthesis convert light energy into chemical energy in the forms of ATP and NADPH. The reactions involve two types of electron flow in the thylakoid membrane. ATP and NADPH generated by light reactions are utilized primarily in the Calvin cycle and photorespiratory cycle.
What is the difference between NADP and NADPH?
NADPH is the reduced form of NADP+, meaning that the latter features an extra hydrogen ion in its chemical structure. In order for NADP+ to transform into NADPH, the former requires two electrons and two hydrogen ions.

What are the components of photosynthesis in a diagram?
Photosynthesis Diagram. According to the diagram of photosynthesis, the process begins with three most important non-living elements: water, soil, and carbon dioxide. Plants begin making their ‘food’, which basically includes large quantities of sugars and carbohydrate, when sunlight falls on their leaves.
What is the process of photosynthesis?
The process of photosynthesis actually becomes possible due to the chlorophyll that is present in plant leaves. During this process of food generation, the following reaction takes place: According to the diagram of photosynthesis, the process begins with three most important non-living elements: water, soil, and carbon dioxide.
How do I create a photosynthesis diagram in Microsoft Word?
Ensure that New is selected from the left pane, select Science and Education from the list of categories in the center, and click the Biology tile from the upper area of the right window. Click the Photosynthesis template icon from the right pane to automatically create a new document and add the photosynthesis diagram in the template to it.
