Proteins in food are broken down into smaller units in the body. What are these units called?

Correct option is D

Correct Answer: (D) Amino acids
Explanation:
→ Amino acids are the fundamental chemical units that serve as the building blocks for complex protein structures in living organisms.
→ During digestion, enzymes break down large dietary protein molecules into absorbable amino acids to repair tissues and support growth.
→ This biochemical breakdown is an essential part of human nutrition, directly impacting health, muscle development, and metabolic function.
→ This conceptual foundation connects dietary intake with physiological health, a key topic in community wellness and human geography resource chapters.
Information Booster:
→ There are 20 standard amino acids required by the human body to manufacture the diverse proteins needed for survival.
→ They are broadly divided into essential amino acids (which must be consumed via diet) and non-essential amino acids.
→ Nitrogen acts as a core chemical element that sets amino acids apart from carbohydrates and simple fats.
→ Ensuring balanced intake of these organic units prevents major nutritional deficiency conditions like Kwashiorkor and Marasmus.
