What factors influence membrane fluidity?
Fluidity is influenced by lipid composition, temperature, and cholesterol content.
How does cholesterol affect membrane fluidity?
Cholesterol decreases fluidity at high temperatures by restricting lipid movement but prevents solidification at low temperatures by disrupting lipid packing.
What are general functions of membrane proteins?
They function as receptors, transporters, enzymes, anchors for cytoskeletal attachment, and in cell recognition and signaling.
What role do aquaporins play in membranes?
Aquaporins are multi-pass membrane proteins that facilitate rapid and selective water transport across membranes.
