Multiple Choice

Why are omega-6 and omega-3 fatty acids classified as essential fatty acids?

Because they are the primary components of all proteins.

Because they are the only fatty acids used for energy production in cells.

Because they can be converted into glucose through gluconeogenesis.

Because the human body cannot synthesize them and they must be obtained from the diet.

Verified step by step guidance

Understand the concept of essential fatty acids: Essential fatty acids are those that the human body cannot synthesize on its own and must be obtained through dietary sources.

Recognize the specific types of essential fatty acids: Omega-6 and omega-3 fatty acids are classified as essential because the body lacks the enzymes required to introduce double bonds at the omega-3 and omega-6 positions in fatty acid chains.

Clarify why the other options are incorrect: Omega-6 and omega-3 fatty acids are not primary components of proteins, nor are they the only fatty acids used for energy production. Additionally, they cannot be converted into glucose through gluconeogenesis.

Explain the biological importance of omega-6 and omega-3 fatty acids: These fatty acids play critical roles in maintaining cell membrane integrity, producing signaling molecules like eicosanoids, and supporting cardiovascular and neurological health.

Conclude with the correct answer: Omega-6 and omega-3 fatty acids are classified as essential because the human body cannot synthesize them and they must be obtained from the diet.
