Photochemical phase of photosynthesis
WebPGA is a three-carbon compound, and the mode of photosynthesis is thus referred to as C 3. In the two other known pathways, C 4 and CAM (crassulacean acid metabolism), the C 3 pathway follows the fixation of CO 2 into oxaloacetate, a four-carbon acid, and its reduction to malate. PGA is formed from 2-carboxy-3-keto-D-arabinitol 1,5-bisphosphate ... WebThe photochemical phase of photosynthesis is also known as light reaction. It is responsible for the formation of high-energy chemical intermediates, ATP and NADPH, and it includes light absorption, water splitting and release of oxygen. It takes place in the granal thylakoids of chloroplasts. Following are the main steps of photochemical phase ...

A light phase requires light and hence is also called photochemical reaction but reactions of dark phase require no light and are purely chemical reactions. Complete answer: >The chloroplast is the green colored plastid that acts as the site for photosynthesis.
WebBlackmann (1905) pointed out that the process of photosynthesis consists of two phases: (1) Light reaction or Light phase or Light-dependent phase or Photochemical phase (2) Dark reaction or Dark phase or Light independent phase or Biochemical phase.
