Dark reaction in photosynthesis is called so because\

Question

Professor PC Thomas Classes · Answer

(b) : Biosynthetic phase (dark or Blackman's reaction) catalyses assimilation of $\mathrm{CO}_{2}$ to carbohydrates. They occur in stroma of chloroplasts. The reactions do not require light. Instead assimilatory power (ATP and NADPH) produced during photochemical phase is used in fixation and reduction of carbon dioxide. All the enzymes required for the process are present in the matrix or stroma of the chloroplast.
