Peroxisomes oversee reactions that neutralize free radicals, which cause cellular damage and cell death. Peroxisomes chemically neutralize poisons through a process that produces large amounts of toxic H2O2, which is then converted into water and oxygen. Which cytoplasmic organelle detoxifies free radicals? Peroxisomes, on the other hand, oversee reactions thatRead More →
Ribosomes engaged in the synthesis of proteins that are destined for secretion are then targeted to the endoplasmic reticulum by a signal sequence at the amino terminus of the growing polypeptide chain. Where are proteins synthesized organelle? Ribosomes are the sites in a cell in which protein synthesis takes place.Read More →
