Question

What is the difference between light dependant and light independent  photosynthesis? T

Jeremiah Allen · Accepted Answer

Light dependent part of photosynthesis is concerned with production of ATP and #NADPH2# utilizing solar energy.

Light independent part of photosynthesis involves reduction of #CO_2# to #C_6H_12O_6#.

In photosynthesis, there are two steps: 1. Hill's or Light's reaction 2. Blackmann's or Dark's reaction In light reaction, solar energy is entrapped by chlorophyll pigment. Solar energy is converted into chemical energy in the form of ATP molecules. This is termed by photophosphorylation . Hydrolysis of water occurs to liberate #O_2# and reducing power in the form of #NADPH2# is produced. Dark reaction involves reduction of #CO_2# to glucose ( #C_6H_12O_6#) utilizing ATPs and #NADPH2# produced during light reaction. As a result, a dark reaction can happen without light but depends on the outcomes of a light-dependent reaction.

undefined Light-independent photosynthesis, also called the Calvin cycle, uses the ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose. Light-dependent photosynthesis uses light energy to drive the conversion of water and carbon dioxide into oxygen and energy-rich molecules such as ATP and NADPH.
