Where does the cyclic photophosphorylation takes place?

the thylakoid membrane
Process of cyclic Phosphorylation: Photophosphorylation of this kind normally takes place in the thylakoid membrane. In cyclic electron flow, the electron starts in a pigment complex called photosystem I.

What causes cyclic photophosphorylation to occur in photosynthesis?

This is called cyclic photophosphorylation. The chloroplast shifts to this process when the ATP supply drops and the level of NADPH rises. Often the amount of ATP needed to drive the Calvin cycle exceeds what is produced in non-cyclic photophosphorylation.

Where does cyclic photophosphorylation takes place in the leaves explain the events in sequence?

Cyclic phosphorylation occurs inside the thylakoid membrane of the chloroplast in the leaves. In it basically electrons are recycled, the thylakoid membranes have photo-systems that contain chlorophyll, this chlorophyll helps in the absorption of light energy.

Where does the oxidative phosphorylation occur?

the mitochondria
Oxidative phosphorylation occurs in the mitochondria of all animal and plant tissues, and is a coupled process between the oxidation of substrates and production of ATP. As the Kreb’s cycle runs, hydrogen ions (or electrons) are carried by the two carrier molecules NAD or FAD to the electron transport pumps.

What are the favorable conditions for cyclic photophosphorylation?

Explanation: Favorable conditions for cyclic photophosphorylation are aerobic and optimum light. Explanation: Diphosphopyridine nucleotide transfers hydrogen from the light reaction to the dark reaction in photosynthesis.

Where do the light independent reactions take place?

stroma
The light-independent reactions represent the known Calvin–Benson–Bassham (CBB) cycle which takes place in the stroma of chloroplasts and is the primary pathway of carbon fixation of C3 plants [119]. The CBB cycle proceeds in three main stages: carboxylation, reduction and regeneration.

What is phosphorylation Where does it take place Class 11?

It occurs on the amino acids such as histidine, lysine, and arginine, etc. ATP is the energy currency. Conversion of ADP to ATP occurs by the addition of one phosphate group in it. It is referred to as oxidative phosphorylation.

Which of the following takes place during oxidative phosphorylation in the mitochondria?

Oxidative phosphorylation occurs in the mitochondria The proteins that mediate the processes of oxidative phosphorylation, including electron transport and ATP synthesis, are embedded within the inner membrane. The majority of energy, at this point, is stored in the reduced electron carriers NADH and FADH2.

Which one does not occur in cyclic photophosphorylation?

NADPH formation does not take place in cyclic photophosphorylation. In this pathway, only a single molecule of ATP is synthesised.

Which of the following is are formed during cyclic photophosphorylation?

NADPH2​, ATP and O2​

Which reaction takes place in the stroma?

the Calvin cycle
The series of biochemical redox reactions which take place in the stroma are collectively called the Calvin cycle or light-independent reactions.

Why does the Calvin cycle take place in the stroma?

Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts). This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.

Where does the process of cyclic photophosphorylation take place?

This process usually takes place in the thylakoid membrane and uses Photosystem I and the chlorophyll P700. During cyclic photophosphorylation, the electrons are transferred back to P700 instead of moving into the NADP from the electron acceptor.

Where does photophosphorylation occur in the thylakoid membrane?

This type of photophosphorylation usually occurs in the thylakoid membrane. The electron begins in a pigment complex called photosystem I in cyclic electron flow. It then further passes from the primary acceptor to ferredoxin and eventually to cytochrome b6f.

How do electrons travel in a non-cyclic way?

Electrons travel in a non – cyclic manner. Electrons from Photosystem I are accepted by NADP. ATP molecules are produced. Both NADPH and ATP molecules are produced. Water is not required. Photolysis of water is present. NADPH is not synthesized. NADPH is synthesized. Oxygen is evolved as a by-product. This process is predominant only in bacteria.
