Question
Which of the following statements is true for the class of biological molecules known as lipids?Group of answer choicesThey are made from glycerol, fatty acids, and phosphate.They contain less energy than carbohydrates of the same number of carbon atoms.They are polymers made by dehydration reactions.They are insoluble in water.They contain nitrogen.
Solution
The statement that is true for the class of biological molecules known as lipids is: "They are insoluble in water."
Here's why:
-
"They are made from glycerol, fatty acids, and phosphate." - This is only true for a specific type of lipids known as phospholipids, not all lipids.
-
"They contain less energy than carbohydrates of the same number of carbon atoms." - This is incorrect. Lipids actually contain more energy per gram than carbohydrates.
-
"They are polymers made by dehydration reactions." - This is more characteristic of carbohydrates and proteins, not lipids.
-
"They are insoluble in water." - This is true. Lipids are hydrophobic, meaning they do not dissolve in water.
-
"They contain nitrogen." - This is not typically true for lipids. While some lipids may contain nitrogen, it is not a defining characteristic of the class.
