Which process is light-independent does not need light?

The Calvin cycle, also called the light-independent reactions, takes place in the stroma and does not directly require light.

Which of the following does not happen during the light-dependent reactions of photosynthesis?

Answer and Explanation: Of the following, carbon fixation does not occur during the light-dependent reactions of photosynthesis.

What is required for both the light dependent and light-independent reactions to proceed?

Explanation: Energy is required in both light dependent and light independent reactions.

Which is required for the light-independent reactions in photosynthesis to occur?

The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.

Which step in photosynthesis does not need light?

The light-independent stage, also known as the Calvin Cycle, takes place in the stroma, the space between the thylakoid membranes and the chloroplast membranes, and does not require light, hence the name light-independent reaction.

Which of the following is not needed for light-independent reactions to occur?

Which of the following is not required for the light-independent reactions of photosynthesis? ATP, stroma, NADPH, and CO2 are required for the light-independent reactions of photosynthesis. H2O is not required for the Calvin cycle.

What are not products of light-dependent reactions?

Understand Light Dependent Reactions : Example Question #2 During the light reactions water is split and the by-product is oxygen. Oxygen is then released back into the atmosphere. Sugars are produced during the Calvin cycle and are not a direct product of the light reactions.

What is not a product of light Dependant reaction?

The correct option is B Glucose. Photosynthesis is a unique process in which green plants synthesise carbohydrates by utilising water and CO2 with the help of chlorophyll in presence of sunlight. During light dependent reaction, assimilatory powers, ATP and NADPH are produced.

Which event does not occur in light reactions?

Answer. Answer: C)CO2,reduced into C6H1206 .

What process does not require oxygen?

Key Terms

Term Meaning
Aerobic Process that requires oxygen
Anaerobic Process that does not require oxygen
Fermentation An anaerobic pathway for breaking down glucose

Which of the following does not happen during photosynthesis?

Final step: Oxidation of carbon to carbon dioxide doesn’t occur during photosynthesis.

Which one of the following is not required for Calvin cycle?

So, the correct option is ‘Light’.

Which one of the following does not belong to the light reactions?

Electron transport chain, chemiosmosis, and photosystem II are all associated with the light reactions of photosynthesis. Therefore, the term Calvin cycle does not belong. Distinguish between autotrophs and heterotrophs.

What are the requirements of light-independent reactions where do light-independent reactions occur?

The requirements or ingredients for light-independent reactions are carbon dioxide and energy in the form of ATP and NADPH.

Which of the following is not a requirement for carrying out photosynthesis?

Oxygen is not essential for the process of photosynthesis because oxygen is released in this process when plants utilize the raw materials i.e., carbon dioxide and water to produce sugars (glucose). Hence, it is not essential to carry out the process of photosynthesis.

Which is not a step of the light independent reaction?

Which is not a step of the light independent reaction? Explanation: Absorption of sunlight in photosystem II is the first step of the light dependent reaction, not the light independent reaction. During the light independent reaction, or the Calvin Cycle, carbon fixation first occurs.

What process does not require sunlight?

Which process does not directly require ATP?

Secondary active transport (cotransport), on the other hand, uses an electrochemical gradient – generated by active transport – as an energy source to move molecules against their gradient, and thus does not directly require a chemical source of energy such as ATP.

Which event in the process of photosynthesis do not require presence of sunlight?

The reduction of carbon dioxide to carbohydrates doesn’t directly depend on the presence of sunlight but on the supply of ATP and NADPH that were formed during the initial phase.

Which of the following is not required for the Calvin cycle reactions of photosynthesis?

Is carbon dioxide required for Calvin cycle?

Reactions of the Calvin cycle Diagram of the Calvin cycle, illustrating how the fixation of three carbon dioxide molecules allows one net G3P molecule to be produced (that is, allows one G3P molecule to leave the cycle).

What are needed for the light-dependent reactions to occur?

The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

Which of the following is not a requirement for carrying out?


Which of the following processes are not a part of the process of photosynthesis?

Option D: Photosynthesis is the process in plants where sunlight, carbon dioxide and water are converted to organic compounds, starch, energy and oxygen. This is not involved in the water cycle and hence, it is the correct option.

What goes in the light dependent?

– water – oxygen – carbon dioxide – NADPH

What are the steps of the light dependent reaction?

what are the steps for light dependent reactions? These reactions occur within specialised membrane discs within the chloroplast called thylakoids and involve three steps: Excitation of photosystems by light energy. Production of ATP via an electron transport chain. Reduction of NADP+ and the photolysis of water.

What is the light independent reactions of photosynthesis?

The Calvin Cycle

  • The Light Independent Reaction of Photosynthesis
  • Photosynthesis (UPDATED)
  • Photosynthesis – Light Dependent Reactions and the Calvin Cycle
  • What is the difference between light independent and dependent reactions?

    Both processes produce energy in the form of ATP.

  • Also,both are enzyme-mediated.
  • Furthermore,both take place in chloroplasts.
  • Moreover,both processes take place in autotrophic organisms.
