The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
Mitochondria produce ATP<span> by </span>respiration<span> and the Kreb's cycle. If you want some extra credit, the cytoplasm of a </span>cell<span> (the fluid </span>cellular<span> matrix) also </span>produces ATP<span>, but by glycolysis.</span>
Interphase. This is the most important stage because during this time the DNA is replicating and the cell is growing. I think it’s about 95% of its life in interphase.
