What are the 2 types of reactions in photosynthesis?
Within the chloroplasts of a plant cell, photosynthesis occurs in two main phases: the light-dependent and light-independent reactions. Within plant cells, chloroplasts are specialized organelles that serve as the sites of photosynthesis.
What is the 2nd reaction of photosynthesis?
The Calvin Cycle The second stage of photosynthesis is the production of glucose from carbon dioxide. This process occurs in a continuous cycle, named after its discoverer, Melvin Calvin. The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose.
What are the reactions in photosynthesis?
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.
What are the two sets of reactions for photosynthesis quizlet?
Photosynthesis can be divided into two sets of reactions – the Light Dependent reactions and the Calvin Cycle (also known as the light independent reactions.
What are the two stages in photosynthesis Class 10?
There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.
Which of the following is the second step of the Calvin cycle?
Reduction. In the second stage of the Calvin cycle, the 3-PGA molecules created through carbon fixation are converted into molecules of a simple sugar – glyceraldehyde-3 phosphate (G3P). This stage uses energy from ATP and NADPH created in the light-dependent reactions of photosynthesis.
What is photosynthesis with diagram?
Photosynthesis vs Cellular respiration
| Photosynthesis | Cellular respiration |
|---|---|
| Photosynthesis is an anabolic process, resulting in the production of organic molecules. | Cellular respiration is a catabolic process, resulting in the oxidation of organic molecules to release energy. |
What occurs in photosystem II?
Photosystem II obtains replacement electrons from water molecules, resulting in their split into hydrogen ions (H+) and oxygen atoms. The oxygen atoms combine to form molecular oxygen (O2), which is released into the atmosphere. The hydrogen ions are released into the lumen.
What is photosynthesis reaction?
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.
What are the 3 steps in the Calvin cycle?
The Calvin cycle reactions can be divided into three main stages: carbon fixation, reduction, and regeneration of the starting molecule.
