CytoskeletonHow does it work?
The cytoskeleton functions as the cell's skeleton. One of its contents are microfilaments that are composed of protein actin. These microfilaments determine the consistency of the cytoplasm, and can change the shape of the cell. Next, intermediate filaments are the objects that strengthen the cell and give it shape, as well, stabilizes the position of the organelles, and the position of the cell relative to other cells. The final content is the microtubules, they make the cell rigid and provide movement for the cell, serves as the highway of the cells that affected by molecular motors, and forms spindle apparatuses during cell division. Why is it important? The cytoskeleton is important because of all that it does. All it is is a boundary, but it can do so much more. The cytoplasm can give shape to the cell and/or make it rigid. It can form spindle apparatuses during the division of the cell, and keep all of the cell intact in the same action! |
Centrioles & CentrosomeHow does it work?
Because of a pair of centrioles, all animal cell are capable of undergoing cell division. Centrioles are cylindrical (like a cylinder) structures composed of short microtubules. From there, the microtubules form nine groups, with three in each group. During cell division, the centrioles form the spindle apparatus associated with the movement of DNA strands. Along with the centrioles, the centrosome is the cytoplasm surrounding the centrioles, and is the heart of the cytoskeletal system. Why are these important? The centrioles and centrosomes are important because of how they work together. As they a part of the cytoskeleton, the centrioles and the centrosome work together to perform one of the main functions of the cytoplasm. This functions consists of the cell division, including the spiral apparatus, all happening inside the boundary of the cell. |
Proteasome
How does it work?
The function of the proteasome is to take the proteins made by the ribosomes and remove them. Proteins that are "tagged" by enzymes are transported into the proteasome and are rapidly disassembled. The proteins are separated back into amino acids and small peptides that can be released into the cytoplasm.
Why is it important?
The Proteasomes are important because of the responsibilities it has. The responsibilities of the proteasome include removing and recycling damaged or denatured proteins, and the breaking down of abnormal proteins, such as those produced within cells infected by viruses.
