Final answer:
Excess protein consumption results in the storage of energy as fat in the body. Hence, 3) is correct.
Step-by-step explanation:
When protein consumption exceeds body needs, the excess energy derived from the protein is stored as fat in the body. Proteins are not stored for later use, so the excess proteins must be converted into glucose or triglycerides to be used as energy or build energy reserves.
Excess amino acids are typically converted into glucose through a process called gluconeogenesis, and then the glucose can be converted into triglycerides and stored as fat if not needed immediately.
