What is cytoplasm and what is its function? What is the role of coat proteins in vesicle trafficking? Describe the vesicle that move from the endoplasmic reticulum (ER) to the Golgi apparatus? What are the functions of the cytoskeleton within the cell?
What structures and cellular processes are microtubules involved in? Which is not a function of the cytoskeleton? a. maintains a cell's shape b. anchors organelles in place within a cell c. allows cell and its organelles to move d. secretes the calcium for bone tissue e. allows...
Neurofilaments (NF) are classed as type IV intermediate filaments foundin the cytoplasm of neurons. They are protein polymers measuring 10 nm in diameter and many micrometers in length. Together with microtubules (~25 nm) and microfilaments (7 nm), they form the neuronal cytoskeleton. What is...
Microtubules are not simple equilibrium polymers, but rather, they are capable of unusual nonequilibrium dynamic behaviors. One such behavior, termed treadmilling, involving the intrinsic flow of subunits from one polymer end to the other, is created by differences in the critical subunit ...
Lysosomes are described as the digestive system of the cell; they contain degradative enzymes. To maintain the function of these enzymes, the lysosome must remain in acidic conditions (around pH 5), in contrast to the neutral pH of the cytoplasm, meaning they require the active transport of pr...

Microtubules are an essential component of the cellular cytoskeleton, providing structural support for the cell as well as serving as tracks for the translocation of organelles during interphase and chromosomes during mitosis. Microtubules form via the head-to-tail polymerization of tubulin dimers into ...
What are the 3 types of cytoskeleton? The filaments that comprise the cytoskeleton are so small that their existence was only discovered because of the greater resolving power of the electron microscope. Three major types of filaments make up the cytoskeleton:actin filaments, microtubules, and interm...
Centromere proteins, like CENP-A, are crucial for its function. 8 Centrosome A centrosome is an organelle that organizes microtubules in animal cells. The centrosome duplicates before cell division to help form the spindle apparatus. 10 Centromere Centromeres are pivotal in maintaining genetic stabilit...
Both cilia and flagella are made of microtubules and are covered by the cell membrane. 9 The primary function of cilia is to move fluid, mucus, or cells over their surface. In the human respiratory system, for example, cilia help move mucus and trapped particles out of the lungs. Flagella...
