Motor proteins, such as myosin, kinesin, and dynein, utilize chemical energy to move along cellular tracks, influencing processes like muscle contraction, organelle movements, and cellular migration. With the ability to translocate using ATP hydrolysis, these proteins play crucial roles in various c

Amoeba cells move by forming pseudopodia, which are cellular extensions due to the cytoskeleton. A study exposed Amoeba cells to drugs disrupting cytoskeletal proteins, showing a significant effect on cell shape. Statistical analysis using Chi-Square test indicated a strong correlation between drug

Platelets play a crucial role in hemostasis and bleeding disorders. This lecture by Dr. Mohammed Alotaibi covers the ultrastructure of platelets, functions of organelles and surface receptors, mechanisms of platelet functions, and the relationship of membrane receptors and granule content in normal

Explore the functions of Kinesin and Dynein, two vital motor proteins involved in intracellular transport. Kinesin drives anterograde movement, while Dynein facilitates retrograde transport along microtubules in cells. Discover the structure, mechanism, and functions of these essential proteins in c

The cytoskeleton, a network of fibers made from proteins, plays a crucial role in maintaining cell structure and shape. Microtubules, which are hollow straight rods made from tubulin proteins, control the movement of membrane-bound organelles and cell components. During cell division, microtubules a
