What are the Reactantsof photosynthesis?

Photosynthesis is a series of chemical reactions that convert carbon dioxide and water into glucose (sugar) and oxygen in the presence of sunlight.

What are the three cycles of photosynthesis?

The Calvin cycle reactions can be divided into three main stages: carbon fixation, reduction, and regeneration of the starting molecule.

What is the process of Photosyn?

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. This transforms the water into oxygen and the carbon dioxide into glucose.

What is nat5 photosynthesis?

Green plants make their own sugars by the process of photosynthesis. Photosynthesis takes place inside the chloroplasts of plant cells. Chlorophyll , the green pigment found in chloroplasts, traps light energy, usually from the sun.

What is the Calvin cycle in photosynthesis?

The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.

What are the 4 steps of photosynthesis?

The overall process of photosynthesis can be objectively divided into four steps/ process:

  • Absorption of light. The first step in photosynthesis is the absorption of light by chlorophylls that are attached to the proteins in the thylakoids of chloroplasts.
  • Electron Transfer.
  • Generation of ATP.
  • Carbon Fixation.

What is nat5 respiration?

Respiration is the cellular process of releasing energy from food and storing it as ATP. Biology.

Which part of plant traps sun?

During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.

What are the 5 steps of light-dependent reactions?

Terms in this set (7)

  • (1st Time) Energy is absorbed from the sun.
  • Water is broken down.
  • Hydrogen ions are transported across the thylakoid membrane.
  • (2nd Time) Energy is absorbed from the sun.
  • NADPH is produced from NADP+.
  • Hydrogen ions diffuse through the protein channel.
  • ADP becomes ATP.

What is Step 2 of photosynthesis?

Stage II is called the Calvin cycle. This stage combines carbon from carbon dioxide in the air and uses the chemical energy in ATP and NADPH to make glucose.
