The cells in our bodies are made up primarily of which four elements?
hydrogen, nitrogen, calcium, and oxygen
hydrogen, nitrogen, sodium, and oxygen
carbon, hydrogen, oxygen, and nitrogen
sodium, potassium, chloride, and calcium

The cells in our bodies are primarily composed of carbon, hydrogen, oxygen, and nitrogen, often referred to as the “big four” elements of life. These elements form the building blocks of essential biomolecules like proteins, nucleic acids, carbohydrates, and lipids, which are crucial for cellular function and structure.

In practical terms, understanding these elements can help you appreciate the chemistry behind nutrition! For instance, when you consume foods rich in these elements, you’re also providing your body with the necessary nutrients to build and repair tissues, produce energy, and maintain homeostasis. So, next time you sit down for a meal, think about how those nutrients contribute to the very cells that make up your body!
