Photosynthesis is composed of two main parts (light-dependent and light-independent). Photosystem I (PS I) and photosystem II (PS II) are alike in many ways. How does photosystem I and photosystem II differ from one another? A) PS I produces glucose while PS II produces ATP. B) PS I occurs in the stroma while PS II takes place in the thylakoid membranes. C) PS I is a light-independent reaction while PS II is a light-dependent reaction. D) PS I absorbs the longer wavelength of light while PS II absorbs a shorter wavelength of light.
