Question

Phospholipids and triglycerides both _________.

A) are hydrophobic molecules
B) contain fatty acids
C) serve as structural components of cell membranes
D) function as enzymes

Answer 1

Phospholipids and triglycerides both serve as structural components of cell membranes. Triglycerides are hydrophobic molecules, while phospholipids have both hydrophobic and hydrophilic regions.

Step-by-step explanation:

Phospholipids and triglycerides both serve as structural components of cell membranes. Triglycerides consist of three fatty acids bonded to glycerol, and they are hydrophobic molecules. Phospholipids have two hydrophobic fatty acid tails and a hydrophilic phosphate head, making them amphipathic and capable of forming large-scale structures.
