What are the cell builders of the body? What is the system that releases energy, and requires oxygen?

1 Answer
  1. Nucleus, Ribosome, ER, Golgi
  2. Mitochondria


  1. "Builders" is a bit vague. So I'll just lay out the purpose of each.
    Nucleus- gives instructions (RNA and DNA)
    Ribosome- makes proteins that make up important parts of the body
    ER(Endoplasmic Reticulum)- makes proteins and fat
    Golgi Apparatus- Packages the proteins, fat, etc and makes some hormones too

  2. "The Mitochondria is the powerhouse of the cell!"
