Cell membranes are composed mainly of _____.Multiple choice question.phospholipidscarbohydratesnucleic acids

Break Down the Problem

1. Identify the components of cell membranes.
2. Determine the primary component from the given options.

Relevant Concepts

• Cell membranes are biological membranes that separate and protect the interior of a cell from its external environment.
• The main structural component of cell membranes is the phospholipid bilayer.

Analysis and Detail

Phospholipids consist of a hydrophilic (water-attracting) "head" and two hydrophobic (water-repelling) "tails." This unique structure allows phospholipids to arrange themselves into bilayers, making them ideal for cell membranes. While carbohydrates and nucleic acids play important roles in cellular functions, they are not the primary components of cell membranes.

Verify and Summarize

Given the options:

1. Phospholipids
2. Carbohydrates
3. Nucleic acids

The correct answer is that cell membranes are primarily composed of phospholipids.

Final Answer

Cell membranes are composed mainly of phospholipids.
