What is the main form of energy storage in animals?
A) Phospholipids
B) Triglycerides
C) Steroids
D) Carbohydrates

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!
