Question

explain how lipids function in the human body by determining whether the following statements are \true\ or \false\: phospholipids are the backbone of cellular membranes. steroids have an entirely different structure from fats. fat forms a protective cushion around major organs. fat is used for short - term energy storage.

Explanation:

1. Phospholipids are amphipathic molecules that arrange themselves in a bilayer to form the basic structure of cellular membranes, so the statement "Phospholipids are the backbone of cellular membranes" is True.
2. Steroids have a characteristic four - ring structure, while fats are triglycerides. They have entirely different structures, so the statement "Steroids have an entirely different structure from fats" is True.
3. Fat deposits around major organs such as the kidneys and liver act as a protective cushion, so the statement "Fat forms a protective cushion around major organs" is True.
4. Fat is used for long - term energy storage, not short - term. Carbohydrates are used for short - term energy storage. So the statement "Fat is used for short - term energy storage" is False.

Answer:

1. True
2. True
3. True
4. False
