What do light reactions in plants produce?
What do light reactions in plants produce?
Photosynthesis begins with the light reactions. The energy is then temporarily transferred to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis. ATP and NADPH are generated by two electron transport chains. During the light reactions, water is used and oxygen is produced.
What are the products of light phase?
Difference between Light and Dark Reaction
| Light Reaction | Dark Reaction |
|---|---|
| The end products are ATP and NADPH. | Glucose is the end product. ATP and NADPH help in the formation of glucose. |
| The water molecules split into hydrogen and oxygen. | Glucose is produced. Co2 is utilized in the dark reaction. |
What are products of light reaction?
The products of light reaction are ATP , NADPH and oxygen of which oxygen is released into the atmosphere , NADPH acts as reducing agent and ATP is consumed during the carbon dioxide fixation in dark reaction.
What does light-independent reactions do?
The light-independent reactions (Calvin cycle) use stored chemical energy from the light-dependent reactions to “fix” CO2 and create a product that can be converted into glucose. The ultimate goal of the light-independent reactions (or Calvin cycle) is to assemble a molecule of glucose.
Which is a light independent reaction?
What are the products of light independent reactions in plants?
What are the products of light independent reaction? Light-independent reactions take place in plant chloroplasts. In this process, sugars are made from carbon dioxide. The process, known as the Calvin cycle, uses products of the light-dependent reactions (ATP and NADPH) and various enzymes.
Where do light independent reactions take place in chloroplasts?
Light-independent reactions take place in plant chloroplasts. In this process, sugars are made from carbon dioxide. The process, known as the Calvin cycle, uses products of the light-dependent reactions (ATP and NADPH) and various enzymes.
What is the difference between light-dependent and light-independent reactions?
The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.
What is the goal of the light-dependent reactions of photosynthesis?
The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions. Within chloroplasts, chlorophyll is the pigment that absorbs sunlight.
