Question

match the term on the left with its description on the right. triglycerides choose an emulsifier a chain of carbon and hydrogen atoms with an acid at one end cholesterol major component of cell membrane a sterol common food fat phospholipids choose fatty acid choose bile choose

Explanation:

Each term is matched to its defining biological function/structure:

1. Triglycerides are the most common form of fat in food and the body's fat storage.
2. Cholesterol is classified as a sterol, a type of lipid with a four-ring structure.
3. Phospholipids form the primary structural component of cell membranes due to their amphipathic nature.
4. Fatty acids consist of a hydrocarbon chain with a carboxylic acid group at one end.
5. Bile acts as an emulsifier, breaking down large fat globules into smaller droplets for digestion.

Answer:

• triglycerides: common food fat
• cholesterol: a sterol
• phospholipids: major component of cell membrane
• fatty acid: a chain of carbon and hydrogen atoms with an acid at one end
• bile: an emulsifier
