Light-dependent reactions use the excited electrons produced by the light-capturing events that are used to produce ATP.
In the structure of a chloroplast, a thylakoid is a membrane-bound compartment where photosynthesis takes place, while a grana is a stack of thylakoids. The grana are interconnected by stroma thylakoids, which help in the exchange of materials within the chloroplast.
The light reactions of photosynthesis take place in the thylakoid membrane of the chloroplast. Here, light energy is captured by pigments and converted into chemical energy in the form of ATP and NADPH.
Stroma
Grana are stacks of thylakoids.They are in stroma.
Chloroplasts contain thylakoids, which are membrane-bound compartments where photosynthesis takes place. Thylakoids are stacked into structures called grana within the chloroplasts.
Photosynthesis takes place in the grana which is present in the chloroplasts of the plant cell.
No, grana are not the site of ATP production within a chloroplast. ATP is primarily produced in the stroma of the chloroplast through the process of photosynthesis. Grana, on the other hand, contain chlorophyll pigments and are responsible for capturing light energy used in the conversion of light energy into chemical energy.
The light phase of photosynthesis takes place in the thylakoid membranes within the chloroplasts. These membranes contain the pigment chlorophyll which captures light energy to initiate the process of photosynthesis.
It takes place on thylokoid membranes.Dark reaction takes place in stroma.
Water is converted into H+ ions and oxygen (O2) is expelled.
Light reaction takes place. The first step of photosynthesis
The structures within the chloroplast, such as the thylakoids, stroma, and grana, play essential roles in photosynthesis. Thylakoids house the photosynthetic pigments and proteins necessary for light-dependent reactions. Grana help increase the surface area for light absorption. The stroma is where the Calvin cycle takes place, leading to the production of sugars.
