Do you agree with this statement?The products of the light-dependent reactions feed intoa. the Calvin cycle. c. glycolysis.b. photosystem I. d. the Krebs cycle
- The light reactions of photosynthesis take place ______. in the stroma in the thylakoid membrane in the cytosol on the cristaeThis past weekend, Mrs. Richardson purchased some new succulents for her house. Explain the type of photosynthesis Mrs. Richardson can expect her plants will perform in detail.In chloroplasts, protons are pumped out of thestroma across the thylakoid membrane, whereas in mito-chondria, they are pumped out of the matrix across thecrista membrane.
