Description

Plasma membrane proteins are inserted into the membrane in the __________________. Endoplasmic reticulum Plasma membrane proteins are inserted into the membrane in the __________________. The address information for protein sorting in a eukaryotic cell is contained in the __________________ of the proteins. Amino acid sequence, folded Proteins enter the nucleus in their __________________ form. Sorting signal Proteins that remain in the cytosol do not contain a __________________. Transport vesicles Proteins are transported into the Golgi apparatus via __________________. The proteins transported into the endoplasmic reticulum by __________________ are in their __________________ form. Transport vesicles, protein translocators, unfolded Where are proteins in the chloroplast synthesized? (a) in the cytosol (b) in the chloroplast (c) on the endoplasmic reticulum (d) in both the cytosol and the chloroplast D (in both the cytosol and the chloroplast) Proteins that are fully translated in the cytosol do not end up in _______. (a) the cytosol. (b) the mitochondria. (c) the interior of the nucleus. (d) transport vesicles. D (transport vesicles) Proteins that are fully translated in the cytosol and lack a sorting signal will end up in ____. (a) the cytosol. (b) the mitochondria. (c) the interior of the nucleus. (d) the nuclear membrane. A (the cytosol) Signal sequences that direct proteins to the correct compartment are _________. (a) added to proteins through post-translational modification.

(b) added to a protein by a protein translocator. (c) encoded in the amino acid sequence and sufficient for targeting a protein to its correct destination. (d) always removed once a protein is at the correct destination. C (encoded in the amino acid sequence and sufficient for targeting a protein to its correct destination)...
