Final answer:
Extra membrane space is important for increased surface area, cellular signaling, and accommodation of cell expansion.
Step-by-step explanation:
The extra membrane space is important for various reasons:
- Increased surface area: Extra membrane space provides more surface area for proteins and other molecules to be embedded in the cell membrane. This allows for a greater number of transport proteins, receptor proteins, and other membrane-associated molecules, which are essential for cell function.
- Cellular signaling: The extra membrane space provides room for the movement and interaction of signaling molecules, such as hormones and neurotransmitters. This allows for efficient communication between cells and tissues.
- Accommodation of cell expansion: During certain cellular processes, such as growth and development, the cell may need to increase in size. The extra membrane space allows for expansion without compromising the integrity of the cell membrane.
