Study Notes

Microfilaments

Thick filaments are composed of myosin

Ribosomes

Free ribosomes function in synthesizing proteins that are released into the cytosol
Attached ribosomes function in synthesizing proteins that are inserted into membranes or exported from the cell

Cytoplasm and Cell Shape

Microfilaments (actin filaments) give structural support to the cytoplasm and shape the cell

Centrioles

In non-dividing cells, centrioles are located near the nucleus and are involved in the formation of cilia and flagella
