The first process in the light-dependent reactions of photosynthesis is?

light absorption


Which simple food is prepared first in the process of photosynthesis?

The first simple food prepared in the process of photosynthesis is glucose. Glucose is synthesized from carbon dioxide and water using energy from sunlight during the light-dependent reactions of photosynthesis.


What is the first stage of photosynthesis is?

cell wall


The first process in the light dependent reactions of photosynthesis?

The first process in the light-dependent reactions of photosynthesis is photon absorption by chlorophyll molecules in the thylakoid membrane of the chloroplast. Absorbed photons then excite electrons in chlorophyll, initiating the transfer of these high-energy electrons through a series of protein complexes known as the electron transport chain.


What are the first 2 processes in photosynthesis?

The light dependent and the light independent reactions.


What are the reactions of the first stage of the photosynthesis called?

This is called the light phase oh photosynthesis as opposed to the dark phase. During the light phase, photons excite enzymes on the thylakoid. Also can be known as Light-Dependent Reactions


Where are the light dependent reactions located?

The light-dependent reactions of photosynthesis take place in the thylakoid membranes of the chloroplasts. This is where sunlight is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH.


In what way is the Calvin Cycle dependent on the first stage of photosynthesis?

The Calvin Cycle is dependent on the first stage of photosynthesis because it relies on the products of the light-dependent reactions, such as ATP and NADPH, to power the conversion of carbon dioxide into glucose.


Light-dependent reactions of photosynthesis?

The light-dependent reactions, or light reactions, are the first stage of photosynthesis. In this process light energy is converted into chemical energy, in the form of the energy-carriers ATP and NADPH. In the light-independent reactions, the formed NADPH and ATP drive the reduction of CO2 to more useful organic compounds, such as glucose.


Can the light dependant reactions occur without the light independent reactions?

No, the light-dependent reactions in photosynthesis cannot occur without the light-independent reactions. The light-dependent reactions, which take place in the thylakoid membranes of chloroplasts, require light energy to produce ATP and NADPH. These molecules are then used in the light-independent reactions (Calvin cycle) to convert carbon dioxide into glucose. Thus, both sets of reactions are interdependent and necessary for the complete process of photosynthesis.


The first pathway of photosynthesis was?

The first pathway of photosynthesis is the light reaction, which is the absorption of light energy from the sun by the chlorophyll in the plant. The pathway that follows this is the dark reaction or carbon fixation.


What are the two stages in photosynthesis?

Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
