What 2 main reactions take place in photosynthesis

Light-dependent and Light-independent reactions

Light-dependent reactions capture the energy of light and use it to make ATP and NADPH. The light-independent reactions use ATP and NADPH to capture and reduce carbon dioxide.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
