Proteins are most important for the following functions except which one?Group of answer choicesantibodiescell structureshormone structuresenergy production

To identify which function proteins are least important for, let's analyze the provided options:

1. Antibodies: Proteins are crucial in the immune system, where they function as antibodies to identify and neutralize foreign objects like bacteria and viruses.

2. Cell Structures: Proteins are vital components of cell structures, involved in maintaining the shape and function of cells. They form the cytoskeleton and other essential cellular networks.

3. Hormone Structures: Many hormones are proteins (or peptides), which play significant roles in signaling and regulatory functions within the body.

4. Energy Production: While proteins can be used for energy, they are not the primary macronutrient for energy production. Fats and carbohydrates are the body's preferred energy sources.

Conclusion

Given these analyses, proteins are least important for energy production compared to the other functions mentioned. Thus, the answer is energy production.
