Six molecules of carbon dioxide enter the cycle, which in turn produces one molecule of glucose or sugar. It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation). Stage One Absorption of Light Energy. In the first step, energy from light is stored in the bonds of adenosine triphosphate (ATP), and nicotinamide adenine dinucleotide phosphate (NADPH). During this process, ATP molecules will be converted to simple sugars. The ATP is broken down to release energy which is used to combine hydrogen (from the light reactions) with carbon dioxide to produce sugar. The stages of photosynthesis take place within the chloroplast, stage 1 within the granum and stage 2 within the stroma. Our tips from experts and exam survivors will help you through. This process consists of the transformation of light into energy, necessary for survival. The light-dependent reactions and the Calvin cycle. The dark reactions do not require direct light, however dark reactions in most plants occur during the day. Photosynthesis is a complex process that can be divided into two or more stages, such light-dependent and light-independent reactions. a year ago. The conversion of unusable sunlight makes plants green. In photosynthetic bacteria, the reaction takes place in the cell membrane and within the cell, but outside of the nucleus. In this reaction the carbon dioxide (CO2) in the atmosphere combines with hydrogen (H) from water molecules and forms glucose. Photosynthesis is a two stage process. Transforming light photons into ATP and the electron carrier NADPH. The overall effect of photosynthesis is to increase the concentration of oxygen in the Earth's atmosphere. Use ATP/NADPH to make glucose. In the first stage, light-dependent reactions or light reactions capture light energy and utilize it to make energy-storage molecules ATP and NADPH.
