Describe the biochemical pathways of the light and dark reactions in c3 photosynthesis begin with a molecule of h2o and co2 and end with a molecule of glucose the light reactions (aka light dependent reactions) occur in the thylakoid of a chloroplast and uses h2o and light to create nadph, atp, and oxygen (which is the waste product).

Light reaction and dark reaction december 28, 2015 leave a comment written by photosynthesis is the process of conversion of light energy into chemical energy which can be utilized by the living organisms.
In plants, photosynthesis is used to convert light energy from sunlight into chemical energy (glucose) carbon dioxide, water, and light are used to make glucose and oxygen the reactions of photosynthesis can be categorized as light-dependent reactions and dark reactions chlorophyll is a key . The light reactions also generate atp by using chemiosmosis through a process called photosphorylation more about essay about compare photosynthesis and cellular . The photosynthesis equation can be written as: from this equation, we can see that plants take in carbon dioxide, water, and light energy as reactants and produce glucose and oxygen as products autotrophs are organisms that produce complex organic compounds from substances present in the . Photosynthesis lay in revealing which of its component en- zymic reactions require an input of energy-rich chemical intermediates that must be formed by the light reactions.
