Light-dependent reactions are the energy conservation phase of photosynthesis. The ultimate aim of these reactions is to convert light energy from the sun into chemical energy that can be utilized to make glucose during dark reactions. The chemical energy is obtained in the form of two high energy metabolites; ATP and NADPH. scarborough temple

WebThey occur in the stroma of the chloroplast and are called the Calvin cycle. Carbon dioxide combines with a 5-carbon sugar called ribulose bisphosphate (RuBP) to form a 6-carbon sugar. This process is known as carbon fixation and is catalysed by the enzyme ribulose bisphosphate carboxylase (rubisco). WebBiology A level OCR. 674 terms. 5. Jamie_Chapman2112.
