Question

True False
Lipids are a major component of cell membranes.

All biomolecules contain carbon, hydrogen, and oxygen.

A covalent bond is when electrons are transferred from one element to another.

Carbohydrates are good for long term energy.

Answer 1

Let's evaluate each statement:

1. Lipids are a major component of cell membranes.
   True - Lipids, particularly phospholipids, are indeed a major component of cell membranes.

2. All biomolecules contain carbon, hydrogen, and oxygen.
   False - While many biomolecules (like carbohydrates, lipids, and proteins) do contain carbon, hydrogen, and oxygen, there are biomolecules such as nucleic acids (e.g., DNA and RNA) that contain nitrogen and phosphorus as well.

3. A covalent bond is when electrons are transferred from one element to another.
   False - A covalent bond is formed when two atoms share electrons. The transfer of electrons refers to ionic bonds.

4. Carbohydrates are good for long term energy.
   False - Carbohydrates are typically used for short-term energy. Fats and lipids are more suitable for long-term energy storage.

In summary:

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