The mitochondria, "the powerhouse of the cell", is the organelle responsible for this key cellular function.
What is cellular respiration (generation of ATP/energy).
400
These proteins are made by white blood cells, and have a special shape to fit into and recognize pathogens/antigens to destroy them or label them for destruction (immune response).
What are antibodies?
