Which statements are true regarding protein transport into peroxisomes? Choose one or more: Like mitochondrial proteins,...

Which statements are true regarding protein transport into peroxisomes? Choose one or more: Like mitochondrial proteins, some peroxisomal proteins arrive via vesicles that bud from the ER. Like proteins transported into mitochondria, proteins can enter the peroxisome in a folded conformation. Like prospective nuclear proteins, some peroxisomal proteins are recognized by receptor proteins in the cytosol. Like proteins destined for the ER, nucleus, or mitochondria, peroxisomal proteins bear a distinct signal sequence. Like proteins transported into the nucleus, proteins must...
