Final answer:
The functions of membranes are acting as a scaffold for biochemical activities and enzyme localization, being a selectively permeable barrier, transporting solutes, facilitating intercellular interaction, and enabling energy transduction.
Step-by-step explanation:
The functions of membranes are:
- Acting as a scaffold for biochemical activities and enzyme localization
- Being a selectively permeable barrier
- Transporting solutes
- Facilitating intercellular interaction
- Enabling energy transduction
Membranes also have other functions, but these are the main ones.
