A phospholipid has

Question: A phospholipid has
Options:
- All of the answers are correct
- 2 fatty acids attached
- Has a phosphate group attached
- Is an important component of the membranes of cells

Option 1: All of the answers are correct. This statement asserts that every listed characteristic is true for a phospholipid, which we will verify by evaluating the other options.
Option 2: 2 fatty acids attached. Indeed, phospholipids typically have two fatty acid tails esterified to a glycerol backbone, forming a diglyceride moiety.
Option 3: Has a phosphate group attached. Phospholipids include a phosphate-containing head group, which is polar and hydrophilic, attached to the glycerol backbone.
Option 4: Is an important component of the membranes of cells. Phospholipids are the fundamental building blocks of cellular membranes, forming a bilayer that provides structure and barrier function.

Analyzing each option in turn:
- If only option 2 were true, that would describe part of the molecule, but it would not capture the full identity of a phospholipid, so it would be incomplete.
- If only option 3 were true, it would describe a feature (phosphate group) but not the entire structure, since there are two fatty acid tails as well.
- If only option 4 were true, it would describe the role of phospholipids but not the chemical makeup; nonetheless, it is a true statement, but not sufficient alone to define a phospholipid.

Considering these together, the combination of two fatty acid tails, a phosphate-containing head group, and the role as a membrane component all align with the defining characteristics of phospholipids. Therefore, the statement that all of the listed attributes are correct accurately captures the full description of a phospholipid.
