Answer 2

Answer:

A light reaction involves the conversion of light energy from sunlight into cellular energy (ATP and NADPH), by the oxidation of water molecule. ... The dark reaction occurs in the stroma of chloroplast, which lacks the chlorophyll pigments.

Differences between light reaction and dark reaction:

Light reaction

Requires Dark reaction of light

Dark reaction

Does not require presence of light

Light reaction

Occurs in thylakoid membranes of grana and stroma lamellae

Dark reaction

Occurs in stroma of chloroplasts

Light reaction

Involves absorption of light energy and its conversion into chemical energy in the form of ATP and NADPH + H+.

Dark reaction

Utilises ATP and NADPH2 for the fixation and reduction of CO2 to form carbohydrates.

Light reaction

Also called photochemical reaction or Hill reaction

Dark reaction

Also called biosynthetic phase or Blackman’s reaction or carbon dioxide fixation or Calvin cycle.
