Question

what are the important events that occur during light reaction of photosynthesis?

Answer 1

Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls.

Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy while NADPH provides the electrons required to fix the CO2(carbon dioxide) into carbohydrates.

Answer 2

The 'light phase' is the initial part of 'photosynthesis'. It refers to the 'conversion' of 'solar energy' into 'chemical energy'. 'Light' is absorbed by 'complexes' created from 'chlorophylls' and 'proteins' known as 'photosystems', that square measure settled within the 'chloroplasts'.

• The pigment, 'chlorophyll', that is needed for the method is 'present' on the 'membrane' of those 'thylakoids' and this is often wherever the 'light method' happens.
• The main 'purpose' of the 'light reaction' is to come up with 'organic energy molecules' like 'adenosine triphosphate' and 'NADPH' that are required for the next 'dark reaction'.
