Chemical reactions that require energy?
endothermic reactions require energy
The light independent reactions (also known as the dark reactions or Calvin cycle) require and from the light dependent reactions in order to operate.?
The light-independent reactions, or Calvin cycle, require ATP and NADPH produced during the light-dependent reactions of photosynthesis. These energy carriers provide the necessary energy and reducing power to convert carbon dioxide into glucose. Although they are termed "light-independent," these reactions still depend on the products of the light-dependent phase to function effectively.
What are the differences between light independent and light dependent?
Light-dependent reactions occur in the thylakoid membranes of chloroplasts and require sunlight to convert light energy into chemical energy, producing ATP and NADPH while splitting water molecules to release oxygen. In contrast, light-independent reactions, also known as the Calvin cycle, take place in the stroma and do not require light directly; they utilize ATP and NADPH produced in the light-dependent reactions to fix carbon dioxide into glucose. Essentially, light-dependent reactions capture energy, while light-independent reactions use that energy to synthesize organic molecules.
What reactions convert light energy to chemical energy?
The light dependent reactions take in the light energy and convert that to chemical energy, but it is in the Calvin cycle (light independent reactions) where the chemical energy is stored in a complex sugar.
Why do light reactions only occur during daylight?
Obviously, there is no sunlight energy for light dependent reactions to occur while calvin cycle AKA light independent phase does not require light as it uses energy in the form of ATP and the NADPH to form sugars
How do the light reactions and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
What are light light dependent reactions?
Light-dependent reactions are those that require light to proceed.
What does a light reaction need in plants?
Light reactions in plants require light energy, water, and chlorophyll. These reactions take place in the thylakoid membranes of chloroplasts, where light energy is captured and used to split water molecules, releasing oxygen. The light energy is also converted into chemical energy in the form of ATP and NADPH, which are essential for the subsequent dark reactions (Calvin cycle) that synthesize glucose.
Which reactions requires or stores energy?
Endothermic reactions require energy while exothermic reactions release energy.
True or false The light reactions of photosynthesis can occur only under light conditions and the dark reactions can occur only during the dark hours?
False. The light reactions of photosynthesis require light to convert solar energy into chemical energy, while the dark reactions (Calvin cycle) do not directly rely on light and can occur in both light and dark conditions. However, the dark reactions are indirectly dependent on the products of the light reactions.
Do anabolic reactions require energy to build complex molecules?
Yes, anabolic reactions require energy to build complex molecules.
The energy sources needed for the light reactions and the carbon reactions respectively are?
The energy sources needed for the light reactions in photosynthesis are light (photons), which are absorbed by chlorophyll. The energy sources needed for the carbon reactions (Calvin cycle) are ATP and NADPH, which are produced during the light reactions.
