Describe the stages of photosynthesis. use the terms thylakoid, light-dependent reactions and light-independent reactions.

Photosynthesis in plants occurs in two stages. These stages are known as the light-dependent reactions and the Calvin Cycle.

The first stage of photosynthesis is the light dependent reactions.  These reactions take place on the thylakoid membrane inside the chloroplast.  During this stage light energy is converted to ATP (chemical energy) and NADPH (reducing power).

The second stage of photosynthesis is the Calvin Cycle.  These reactions occur in the stroma of the chloroplast.  Energy from ATP and electrons from NADPH are used to convert carbon dioxide into glucose and other products.

lesson summarykaryotypes a genome is the full set of all the genetic information that an organism carries in its dna. chromosomes arebundles of dna and protein found in the nucleus of a eukaryotic cell.

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.
