Question

Differentiate Light reaction and Dark reaction (location of occurrence)

Answer 1

Answer:

ExplanThe demand for light: A light reaction demands the source of light energy for the breakdown of water into oxygen, while dark reaction does not need a light source.

Site of occurrence: A light reaction resides within the thylakoid membrane, whereas dark reaction resides inside the aqueous stroma of the chloroplast.ation:

Light and dark reaction are the two phases that complete the process of photosynthesis in photosynthetic organisms.

Answer 2

Light reaction takes place at GRANA.

Here light energy is converted to chemical energy.

It involves pigments.

And occurs by two methods - Cyclic Photo Phosphorylation and Non Cyclic Photo Phosphorylation.

Dark reaction occurs at the STROMA of Chloroplast.

Even though it’s light Independent, it requires the products of Light reaction (ATP and NADPH ). Here CO2 is reduced to CARBOHYDRATE.
