What is the function of cell cortex?A.Although actin is found throughout the cytoplasm of a eukaryotic cell, in many cells it is highly concentrated in a layer just beneath the plasma membrane. In this region, called the cell cortex, actin filaments are linked by actin-binding proteins into...

The key difference between G-actin and F-actin is that G-actin is a form of actin with a globular configuration. At the same time, F-actin is a form of act
Once myosin and actin interact, myosin undergoes the power stroke that causes force production/cell shortening. Relaxation occurs when cytosolic [Ca2+] is reduced by pumping Ca2+ back into the SR by SERCA2. The amount of force production is primarily dependent on the amount of calcium that is...
How does the cytoskeleton specifically contribute to neuronal function? The neuronal cytoskeleton, which is composed of microtubules (MTs), actin filaments and neurofilaments, enacts importantfunctions in both the establishment and maintenance of neuronal polarity, morphology and integrity of axons(Luo, 20...
What function occurs as a result of the contractions in the skeletal muscle and smooth muscle? (a) Where is teres major located? (b) Explain its action. What is the action of the risorius? Name and describe the location and actions of the muscles typically used ...
What is the function of CapZ and tropomodulin in the sacromere?A.a. to center myosin thick filamentsB.b. to attach actin thin filaments to the Z diskC.c. to maintain a constant actin thin filament lengthD.d. to make contraction sensitive to Ca 2+的答案是
Fibrils, within this context, often refer to the finer structures that make up these larger fibers or that are components of the extracellular matrix, such as collagen fibrils, which are crucial for the structural integrity and function of tissues. 9 At the molecular level, fibers can refer to...
