The eukaryotic cell nuclear transport system selectively mediates molecular trafficking to facilitate the regulation of cellular processes. The components of this system include diverse transport factors such as importins and nuclear pore components that are precisely organized to coordinate cellular events. In Cell Biology (Third Edition), 2017. Actin-Based Movements of Organelles in Other Cells. Like Nitella, budding yeast cells transport vesicles along bundles of actin filaments from the mother to the bud (Fig. 37.11), although the movements of these solitary vesicles do not produce cytoplasmic streaming. 2021-04-24 · Transport of these vital substances is carried out by certain classes of intrinsic proteins that form a variety of transport systems: some are open channels, which allow ions to diffuse directly into the cell; others are “facilitators,” which, through a little-understood chemical transformation, help solutes diffuse past the lipid screen; yet others are “pumps,” which force solutes through the membrane when they are not concentrated enough to diffuse spontaneously.

Transport across cell membranes: Paul Andersen describes how cells move materials across the cell membrane. All movement can be classified as passive or active. Passive transport, such as diffusion, requires no energy as particles move along their gradient. Active transport requires additional energy as particles move against their gradient.

Stomatal guard cells are widely recognized as the premier plant cell model for membrane transport, signaling, and homeostasis. This recognition is rooted in half a century of research into ion transport across the plasma and vacuolar membranes of guard cells that drive stomatal movements and the signaling mechanisms that regulate them.

This scenario, however, is unlikely to occur in the intestine because of the efficient dephosphorylation of phosphorylated thiamin derivatives in the lumen by the abundant intestinal phosphatases.
