Is CO2 oxidized or reduced in photosynthesis?
The process During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.
Is photosynthesis a redox process?
Photosynthesis is the conversion of light energy into chemical energy. The primary event is light-driven electron transfer — a redox reaction — and it sets in motion a chain of electron transfers upon which all life ultimately depends.
How is carbon dioxide reduced and water oxidized 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 is oxidized and which is reduced during photosynthesis?
What Is Oxidized and Reduced in Photosynthesis and Cellular Respiration? During photosynthesis, CO2 is reduced to glucose and H2O is oxidised to release O2.
Why photosynthesis is oxidation-reduction?
The reduction of carbon dioxide into sugars and oxidation of water into molecular oxygen is involved in photosynthesis. To produce carbon dioxide and water, the reverse reaction, respiration, oxidizes sugars. Complete answer: Redox (oxidation-reduction) reactions are characterized by electron transfer.
What oxidizes water in photosynthesis?
PSII is a multi-subunit membrane protein that acts as the first light-transducing complex in the redox pathway of oxygenic photosynthesis. It uses the energy of sunlight to oxidize water, producing dioxygen and protons, and reduces lipid-soluble plastoquinone.
Why is photosynthesis called redox?
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.
Why photosynthesis is oxidation-reduction reaction?
What is the photosynthesis process?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Why do we say that photosynthesis is a kind of redox reaction?
Does photosynthesis reduce CO2?
Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2. However, these processes are not in balance. Not all organic matter is oxidized.
