2.1 Structures & Functions of Eukaryotic Cells (CQ - Exam) Flashcards
Describe 4 functions of the cell membrane.
- Protective barrier
- Regulate transport
- Allow cell recognition
- Provides anchoring sites
Why are the properties of the cell membrane not adequately explained by the presence of lipids alone in their structure?
Cell membrane has the ability to do cell signaling, lipids do not have this ability but proteins do
xplain why a cell membrane is a dynamic structure, rather than static such as the wall of a building.
The cell membrane has a fluid mosaic model that allows for fluidity and movement, lipid bilayer, and protein movement. All that are abilities that would not be able to be provided if it was a wall of a building
Explain why it is beneficial for a cell to use enzymes that work best at an acidic pH inside lysosomes.
if an enzyme were to fall out, then the acidity works as a safety guard because then the enzymes are less likely to break down the parts of the living cell Because it would become neutral and inactive
