Protein Trafficking (ER)
This term describes the maturation process of the Golgi cisternae, moving from the cis face to the trans face.
What is Cisternal Progression.
This cellular process involves engulfing large particles or bacteria, commonly performed by immune cells like macrophages
What is Phagocytosis.
This translocon complex in the ER membrane is a key component in the translocation of newly synthesized proteins into the ER.
What is Sec 61.
This filamentous protein is crucial for cell movement and shape, forming the cytoskeleton's microfilaments.
What is Actin.
This term refers to the action of myosin pulling actin filaments during muscle contraction, powered by ATP hydrolysis.
What is Power Stroke.
This type of protein, exemplified by clathrin and COPII, helps in the formation and budding of transport vesicles.
What is Coat Protein.
Often referred to as 'cell drinking', this process involves the ingestion of liquid into a cell by the budding of small vesicles
This complex facilitates the import of proteins into mitochondria.
What is TOM, short for 'Translocase of the Outer Mitochondrial membrane'.
This dynamic process describes the polymerization at one end of an actin filament and depolymerization at the other, wherein the overall effect is that the call seems to maintain a constant length.
The basic contractile unit of muscle fiber, this structure is defined from one Z disk to another in a myofibril.
What is sarcomere.
This factor facilitates the exchange of GDP for GTP, activating GTPase proteins involved in cell signaling.
What is Guanine Exchange Factor.
This receptor in cell membranes binds and internalizes low-density lipoproteins, playing a key role in cholesterol metabolism.
What is LDL Receptor.
This type of molecular chaperone assists in the proper folding of proteins within cells, an example being HsC in mitochondrial import.
What is Chaperonin.
This protein binds to actin monomers, preventing them from polymerizing into filaments, thereby regulating actin dynamics.
What is Thymosin Beta 4.
This structure serves as the anchoring point for actin filaments in the muscle sarcomere.
What is Z Disk.
This structure functions as a sorting station between the ER and Golgi apparatus.
What is ERGIC, short for 'ER-Golgi intermediate compartment.
This protein forms a triskelion shape and is involved in the formation of coated vesicles during endocytosis.
What is Clathrin.
This cytosolic receptor recognizes and transports proteins with a peroxisomal targeting signal to peroxisomes.
What is Pex 5.
This protein caps the barbed end of an actin filament, stabilizing it and regulating its length.
This type of muscle contraction is involuntary, controlled by the autonomic nervous system, and is found in organs like the intestine and bladder.
What is Smooth Muscle Contraction.
This term refers to the part of a cell or tissue that is nearest to the lumen or external environment, especially in epithelial cells.
What is Apical.
This GTPase enzyme is critical for 'pinching off' vesicles from membranes during processes like receptor-mediated endocytosis.
What is Dynamin.
This type of protein forms channels that allow the passage of certain ions and small molecules across the outer mitochondrial membrane.
What is porin.
This regulatory protein wraps around actin filaments in muscle cells and, along with troponin, controls muscle contractions.
What is Tropomyosin.
This voluntary muscle contraction involves the sliding filament theory, where actin and myosin filaments slide past each other.
What is Skeletal Muscle Contraction.
