6.2/6.3 Reflections

- I learned that Membranes regulate the transport of substances across the boundary, which only allows only certain substances to pass. Also the membrane maintains a specific chemical environment within each compartment it encloses.
- What I have found difficult to learn about is the selectively permeable membrane and how it just chooses to select some substances over other substances and how it blocks the passages of some substances altogether.
- How do biological systems regulate?- They are able to regulate the transport of substances across the boundary which allows certain to substances to pass so membranes can maintain a specific chemical environment.
