Cells in the human body require which of the following?

The rationale for selecting the option that includes oxygen, nutrients, and waste removal lies in the fundamental needs of cells to maintain homeostasis and support metabolic processes.

Cells thrive in environments where they have access to oxygen, which is essential for aerobic respiration—a process that provides the energy necessary for cellular functions. Nutrients, such as carbohydrates, proteins, fats, vitamins, and minerals, are crucial as they serve as building blocks for cellular structures and are involved in various biochemical pathways that support growth, repair, and energy production.

Additionally, waste removal is a critical process that allows cells to expel byproducts of metabolism, such as carbon dioxide and other toxic substances, which can accumulate and become harmful if not adequately cleared. Therefore, the combination of oxygen, nutrients, and effective waste removal underscores the holistic requirements of cells in the human body to function efficiently and sustain life.

The other options do not capture the comprehensive necessities for cell survival. Focusing solely on water or inadequate sodium levels overlooks the broader spectrum of essential nutrients and oxygen required for optimal cellular functions. Moreover, the mention of muscle recovery only addresses a specific context and doesn't encompass the general needs of all cells.
