Question

What is true about all lipids in all cells? Select all that apply. A) Are made from glycerol and fatty acids B) Contain nitrogen C)Have low energy content D) Do not dissolve well in water E) Contain phosphate

Answer 1

Lipids are hydrophobic and do not dissolve well in water; some lipids such as phospholipids contain phosphate and are key components of cell membranes.

Step-by-step explanation:

What is true about all lipids in all cells? The characteristics of lipids include being largely nonpolar in nature, which accounts for their hydrophobic ("water fearing") properties, meaning they do not dissolve well in water. Furthermore, lipids are a diverse group of compounds, with some like phospholipids containing phosphate and glycerol in addition to fatty acids, which are the main component of cell membranes in all living things. While not all lipids are made from glycerol and fatty acids, a common type known as triglycerides are. It's important to note that lipids generally contain high energy content, rather than low, due to their dense hydrocarbon structures that store energy.

Answer 2

The true statements about all lipids in all cells are that they are made from glycerol and fatty acids, and they do not dissolve well in water. Not all lipids contain nitrogen or phosphate, and they have a high energy content.

Step-by-step explanation:

What is true about all lipids in all cells? Among the options provided:

A) Are made from glycerol and fatty acids - This is true for some lipids, like triglycerides and phospholipids, which are the main components of cell membranes.

B) Contain nitrogen - This is not generally true as lipids typically do not contain nitrogen.

C) Have low energy content - This is incorrect, as lipids have a high energy content and are used for long-term energy storage.

D) Do not dissolve well in water - This is true, because lipids are hydrophobic due to their nonpolar nature, they are insoluble in water.

E) Contain phosphate - This is true only for phospholipids, which contain a phosphate group, but not all lipids contain phosphate.

To summarize, the correct statements about all lipids in all cells are that they are made from glycerol and fatty acids (although not exclusively) and they do not dissolve well in water.
