What functions do proteins serve in the body?

Including structure, movement, defense, and signaling
Energy storage and insulation
Serving as biological catalysts
Forming the cell membrane

The correct answer is: Including structure, movement, defense, and signaling

Proteins have many important functions in the body and the molecules that carry out these functions are known as enzymes. Proteins are crucial for the structure of our bodies - they are a major component of skin, muscle, and bones. They also help with movement, defense against disease and injury, as well as signaling between cells and tissues. Option B is incorrect because proteins do not serve as energy storage or insulation. Option C is incorrect because while proteins can act as enzymes and act as biological catalysts, this is not their only function. Option D is incorrect because proteins do not form the cell membrane - lipids are the main component of cell membranes.
