WebThe Calvin cycle is also called the dark reactions or light-independent reactions because it is the part that doesn't need energy from the sun to happen. The Calvin cycle takes place within the stroma of the chloroplast. This is where plants make sugar molecules that they can use to make other essential components, and that all other organisms ... WebA) the light-dependent reactions can occur only in the light, the light-independent reactions only in the dark. B) photorespiration is more efficient at producing glucose than is photosynthesis. C) the light-dependent reactions produce the energy-rich compounds that are used to run the light-independent reactions.
