What process allows cells to receive nutrients for growth and reproduction?

1. Metabolism

2. Homeostasis

3. Digestion

4. Respiration

The correct answer is: Metabolism

Metabolism refers to the entire range of biochemical processes that occur within a living organism to maintain life. It encompasses all the chemical reactions that convert nutrients into energy and the building blocks necessary for cellular growth and reproduction. This includes both catabolic reactions, which break down molecules to release energy, and anabolic reactions, which utilize that energy to synthesize essential components like proteins and nucleic acids. While metabolism is the overarching process responsible for nutrient uptake and utilization, digestion is specifically about breaking down food into simpler forms. Homeostasis refers to maintaining stable internal conditions, and respiration is primarily associated with gas exchange and energy production from nutrients. Thus, metabolism is the correct choice as it encompasses the complete process by which cells receive and utilize nutrients for growth and reproduction.
