The ATP and NADPH formed in the light-dependent stage are used as the energy and electron carriers to transfer the energy to the next stage of photosynthesis which is called the light-independent stage or the dark reaction or the Calvin Benison Cycle. Plant cells need light energy, water and carbon dioxide to carry out the steps of photosynthesis. NADPH is often kept at higher concentration in the cytosol than NADP+, to allow for the easy reduction of small molecules into larger macromolecules. These reactions do not need light energy to proceed and are sometimes called the light-independent reactions. When cellular energy declines below a certain threshold, the cell dies and the tissue degenerates. This can be contrasted to NADH, which is often found in lower concentration than NAD+.
