How many ATP and NADPH are consumed in the process? 9 What is primary function of the chloroplast? NADPH is an electron carrier that accepts a pair of high-energy electrons and transfers them, along with most of their energy, to another molecule. Because nitrogen can move around in the plant, older growth often yellows more than the new growth. organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis. The Calvin Cycle uses 6 molecules of carbon dioxide to ultimately produce a single 6-carbon sugar molecule. The variations of chlorophyll-b and the bacterial version are indicated above. Most leaves appear green because the chloroplasts in plant cells give plants their green color. NADPH, in turn, is used to reduce carbon dioxide (CO2) into sugars, such as glucose.
