|
Nuclear Membrane/Envelope |
Surrounds nucleus. |
|
|
Nuclear Pores |
Allow selective two-way exchange of material. |
|
|
Nucleolus |
Subsection of nucleus where rRNA is synthesized. |
|
|
Outer Membrane of Mitochondria |
Barrier between cytosol and inside of mitochondrion. |
|
|
Cristae |
Infoldings that contain molecules and enzymes for ETC. |
|
|
Intermembrane Space |
Space between inner and outer membranes of mitochondria. |
|
|
Mitochondrial Matrix |
Innermost space from where protons are pumped for proton-motive force and ATP generation. |
|
|
Mitochondria |
Semi-autonomous power plants. Have own genes and can replicate independently via binary fission. |
|
|
Lysosomes |
Membrane-bound structures containing hydrolytic enzymes that break down substrates. |
|
|
Rough Endoplasmic Reticulum |
Studded with ribosomes that permit the translation of proteins destined for secretion directly into its lumen. |
|
|
Smooth Endoplasmic Reticulum |
Primarily used for lipid synthesis and detoxification of drugs and poisons. Transports proteins from RER to Golgi Apparatus. |
|
|
Golgi Apparatus |
Modifies cellular products from SER, repackages them into vesicles, and then transports them to other parts of cell or excretion via exocytosis. |
|
|
Peroxisomes |
Contain hydrogen peroxide for breaking down very long-chain fatty acids via beta oxidation. Also help synthesize phospholipids and pentose phosphate pathway. |
|
|
Microfilaments |
Made of solid rods of actin filaments. Reinforce structure of cell and allow for movement with myosin. Plays a role in cytokinesis. |
|
|
Microtubules |
Hollow tubes of tubulin. Provide pathways for motor proteins like kinesin and dynein. Compose cilia and flagella, and organized in centrioles at the centrosome. |
|
|
Intermediate Filaments |
Diverse group of filamentous proteins. Provide cell to cell adhesion, cytoskeleton support, and help anchor organelles. |
