1) proteins
2) amphipathic
3) hydrophobic
4) phosphatidylserine
5) cholesterol
6) lipid bilayer
7) phospholipids
8) fatty acid tails
9) lipid monolayer proteins
10) glycolipids
11) lipids
12) sterols
13) hydrophilic head groups
14) phosphatidylcholine
15) sugars

Answer 1

The specialized functions of different membranes are determined by the proteins they contain. Membrane lipids are amphipathic molecules, composed of a hydrophilic portion and a hydrophobic portion.

Step-by-step explanation:

The specialized functions of different membranes are largely determined by the proteins they contain. Membrane lipids are amphipathic molecules, composed of a hydrophilic portion and a hydrophobic portion. All cell membranes have the same lipid bilayer structure.

Membranes function due to the proteins they contain, while their amphipathic lipids possess both hydrophilic and hydrophobic qualities, forming a consistent lipid bilayer structure across all cell membranes.

All cell membranes have the same lipid bilayer structure.
