What molecules are used to capture the light in photosynthesis?
Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
What two molecules are used in photosynthesis?
Photosynthesis uses carbon dioxide and water to assemble carbohydrate molecules (usually glucose) and releases oxygen into the air. Eukaryotic autotrophs, such as plants and algae, have organelles called chloroplasts in which photosynthesis takes place.
What are the 2 requirements for light reaction of photosynthesis?
Photosynthesis occurs in two stages. Stage I is called the light reactions because it requires sunlight or artificial light. This stage uses water and changes light energy from the sun into chemical energy stored in ATP and NADPH (another energy-carrying molecule). This stage also releases oxygen as a waste product.
What two molecules are produced by the light reactions and used to power the Calvin cycle?
This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
What are the two reactions in the process of photosynthesis?
The reactions that make up the process of photosynthesis can be divided into light-dependent reactions, which take place in the thylakoids, and light-independent reactions (also known as dark reactions or the Calvin cycle), which take place in the stroma.
What two products of the light reactions are used up in the Calvin cycle?
What two molecules are produced in the light reaction?
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.
Which of the following molecules is produced during the light reactions of photosynthesis and used in the Calvin cycle reactions?
Explanation: ATP and NADPH are produced during the light dependent reaction, and are reactants necessary for the light independent reaction (Calvin Cycle) to occur. During the light independent reaction, ATP and NADPH are used to convert phosphoglycerate molecules (PGA) to glyceraldehyde-3-phosphate molecules (G3P).
What are the 2 types of reactions?
Types of Chemical Reactions
- Synthesis reactions. Two or more reactants combine to make 1 new product.
- Decomposition reactions. A single reactant breaks down to form 2 or more products.
- Single-replacement reactions.
- Double-replacement reactions.
- Combustion reactions.
What are the light reactions in photosynthesis?
During the light-dependent stage (“light” reactions), chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these leave the chlorophyll and pass along a series of molecules, generating formation of NADPH (an enzyme) and high-energy ATP molecules.
What are the 3 products of light reaction?
Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH.
What are the products of light independent reactions of photosynthesis?
The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose….
