Help prevent injury to vital organs
Correct Answer(s)
A. Store energy
A. Help prevent injury to vital organsExplanation
Lipids are a diverse group of molecules that serve various functions in the body. One of their primary roles is to store energy. Lipids, such as triglycerides, store energy in the form of fat, which can be utilized by the body when needed. Additionally, lipids also play a crucial role in protecting vital organs. They form a protective layer around organs, acting as a cushion and helping to prevent injury.Rate this question:

Lipids are soluble in...
-
Water
-
Coke
-
Ether
-
Chloroform
Correct Answer(s)
A. Ether
A. ChloroformExplanation
Lipids are not soluble in water because they are hydrophobic, meaning they repel water. However, they are soluble in organic solvents such as ether and chloroform. These solvents have nonpolar characteristics that allow them to dissolve lipids, which are also nonpolar in nature.Rate this question:

Two types of lipids are...
-
Steroids and proteins
-
Fatty acids and nucleic acids
-
Fatty acids and steroids
-
Proteins and enzymes
Correct Answer
A. Fatty acids and steroidsExplanation
Fatty acids and steroids are two types of lipids. Fatty acids are long chains of hydrocarbons with a carboxyl group at one end, and they are important for energy storage and membrane structure. Steroids, on the other hand, are a class of lipids with a specific four-ring structure, and they have various physiological functions such as hormone regulation and membrane fluidity. Therefore, the correct answer is fatty acids and steroids.Rate this question:

What are oils made of?
-
Dehydration synthesis
-
Lipids
-
Fatty acids
-
Glycerol
Correct Answer(s)
A. Dehydration synthesis
A. Fatty acids
A. GlycerolExplanation
Oils are made up of lipids, which are organic compounds that are insoluble in water. Lipids consist of fatty acids and glycerol. Dehydration synthesis refers to the chemical reaction that occurs when a molecule of water is removed to join two smaller molecules together, such as in the formation of a lipid molecule. Therefore, all three options - dehydration synthesis, fatty acids, and glycerol - are correct explanations for what oils are made of.Rate this question:
