WebPhotosynthesis is a process that takes place in the leaves of plants where carbon dioxide and water is converted to carbohydrates, also producing oxygen. This process occurs within the chloroplasts, on the thylakoid membranes that are stacked into structures called grana. In this exercise you will examine the process of ATP synthesis that ... WebThe important thing from the photosynthesis point of view is that it's this membrane. And on the outside of the membrane, right here on the outside, you have the fluid that fills up the entire chloroplast. So here you have the stroma. And then this space right here, this is the inside of your thylakoid.
