Why is photosynthesis called an oxidation reduction process?

Why is photosynthesis called an oxidation reduction process?

Explanation: Answer. During oxidation a substance tends to loose its electrons whereas duringreduction a substance tends to gain electrons. Photosynthesis is a processin which plants containing chlorophyll convert the carbon dioxide into sugars in the presence of sunlight by a set ofredox reactions.

Is photosynthesis an oxidation reaction?

Photosynthesis involves oxidation and reduction by oxidizing the oxygen in water and reducing the carbon in carbon dioxide.

Where does oxidation and reduction occur in photosynthesis?

Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.

Why photosynthesis is reduction reaction?

Photosynthesis is a redox process where oxidation and reduction both occurs. During photosynthesis, water gets oxidized to oxygen (O2). In photosynthesis, CO2 gets reduced to carbohydrates. NADP+ getting reduced to NADPH is the reduction half and water giving rise to oxygen is the oxidation half.

Which of the following is reduced during photosynthesis?

During true photosynthesis, the carbon dioxide is reduced and water is oxidized. The carbon dioxide is reduced to glucose and the water is oxidized to release oxygen in the presence of sunlight to synthesize nutrients such as carbohydrates in the form of glucose and release oxygen.

Which one undergoes reduction in photosynthesis?

In the process of photosynthesis, the carbon dioxide undergoes reduction to give sugar molecules. The NADPH molecule formed during the oxidation of water gives away its electrons and releases protons and NADP+. These electrons and hydrogen atoms are used for the reduction of carbon dioxide.

Is the NADP+ oxidized or reduced in the process of photosynthesis?

NADP is the reducing agent produced by the light reactions of photosynthesis and is consumed in the Calvin cycle of photosynthesis and used in many other anabolic reactions in both plants and animals.

What is oxidized and reduced in photosynthesis and cellular respiration?

Redox reactions are an important process for cellular respiration and photosynthesis. In respiration, electrons are transferred from glucose molecules to oxygen. Therefore, glucose is oxidized, while oxygen is reduced in cellular respiration.

What is oxidized and what is reduced in a combustion reaction?

Oxygen (in its elemental form) is a crucial reactant in combustion reactions, and it is also present in the products. In combustion, the oxygen (O2) is reduced and the other elements are oxidized.

What undergoes oxidation in photosynthesis?

In the process of photosynthesis, the water undergoes oxidation to give oxygen molecules. The water molecule splits into an electron, oxygen, and hydrogen atoms in the presence of sunlight. The electrons reduce carbon dioxide to form sugar molecules or glucose. The oxidation state of carbon decreases in this process.

What does NADP+ do in photosynthesis?

NADP+ functions as a carrier to transfer high energy electrons from chlorophyll to other molecules.
