9.Ribosome – organelle that links amino acids together to form proteins.
Neutron – A neutral charged subatomic particle found in the nuclei of atoms.
protein phosphatase – An enzyme that removes phosphate groups from (dephosphorylates) proteins, often functioning to reverse the effect of a protein kinase.
mitochondrion – in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration, which produces ATP
