- Ribosome attached to the cytosolic face of the endoplasmic reticulum. The site of synthesis of proteins that enter the endoplasmic reticulum.
- Organelle in green algae and plants that contains chlorophyll and carries out photosynthesis.
- Ribosome that is free in the cytosol, unattached to any membrane.
- Large internal compartment of the mitochondrion.
- Membrane proteins anchored in the endoplasmic reticulum (ER) membrane by a single transmembrane α helix contained at their C-terminus.
- Monomeric GTPase of the Ras superfamily present in both cytosol and nucleus. Required for the active transport of macromolecules into and out of the nucleus through nuclear pore complexes.
- Membrane-bounded organelle, about the size of a bacterium, that carries out oxidative phosphorylation and produces most of the ATP in eukaryotic cells.
- Bind to both the export signal and nuclear pore complex proteins to guide their cargo through the nuclear pore complex to the cytosol.
- Proteins first fully synthesized in the cytosol and then translocated into mitochondrial subcompartments as directed by one or more signal sequences.
- Signal sequence or signal patch found in proteins destined for the nucleus that enables their selective transport into the nucleus from the cytosol through the nuclear pore complexes.
- Protein that escorts macromolecules either into or out of the nucleus: nuclear import receptor or nuclear export receptor
- Endoplasmic reticulum with ribosomes on its cytosolic surface. Involved in the synthesis of secreted and membrane-bound proteins
- Form a protein translocator that participates in the import of proteins into peroxisomes.
- One of two concentric membranes comprising the nuclear envelope; contnuous with the outer nuclear membrane; contains specific proteins as anchoring sites for chromatin and the nuclear lamina.
- T/F: The nuclear membrane is freely permeable to ions and other small molecules under 5000 daltons.
- Channel-forming proteins of the outer membranes of bacteria, mitochondria, and chloroplasts.
- Transport of proteins from one cell compartment to another by means of membrane-bounded intermediaries such as vesicles or organelle fragments.
- mRNA engaged with multiple ribosomes in the act of translation.
- Mitochondrial membrane that encloses the matrix space and forms extensive invaginations called cristae.
- Protein-sorting signal that consists of a specific three-dimensional arrangement of atoms on the folded protein's surface.
