Answer
Triglycerides are the main form of energy storage in animals.
Solution
The correct answer is:
**B) Triglycerides**
**Explanation:**
- **Triglycerides** are the main form of energy storage in animals. They are stored in adipose (fat) tissue and can be broken down to release fatty acids and glycerol when the body needs energy. Triglycerides are highly efficient for long-term energy storage because they contain more energy per gram compared to carbohydrates.
- **Phospholipids** are primarily components of cell membranes and are not used for energy storage.
- **Steroids** serve various functions, including acting as hormones (e.g., testosterone, estrogen) and structural components of cell membranes (e.g., cholesterol), but they are not a primary energy storage form.
- **Carbohydrates**, such as glycogen, are used for short-term energy storage in muscles and the liver. While they are important for energy metabolism, triglycerides are the main storage form for long-term energy reserves.

Simplify this solution Beyond the Answer
The main form of energy storage in animals is triglycerides! These fat molecules provide a highly efficient way for animals to store energy, as they contain more than double the energy of carbohydrates. When energy is needed, enzymes break down triglycerides into fatty acids and glycerol, which can then be utilized for energy through various metabolic pathways. In addition to being energy powerhouses, triglycerides also play an essential role in insulation and protecting vital organs. So, next time you munch on some fats, remember – you’re tapping into a well of energy that’s been refined over millions of years of evolution!
