Molecular motors are tiny proteins that move within cells, playing a crucial role in various biological processes. They convert chemical energy from molecules like ATP into mechanical work, allowing them to transport cellular materials, such as organelles and vesicles, along structures called microtubules. This movement is essential for maintaining cell function and organization. These motors can be categorized into different types, including kinesins and dyneins, each with specific roles. For example, kinesins typically move towards the cell's outer edges, while dyneins transport materials back toward the center. Together, they ensure that essential components are delivered where needed, supporting overall cellular health.
