A single bidirectional transport mechanism appears to be responsible for axonal transport. (From Human Anatomy and Physiology Marieb 8th Ed.)
Active transport is the type of transport mechanism that goes against the concentration gradient.
Kinesin is responsible for anterograde transport within cells.
it allows humoral factors in hypophyseal portal circulation or systemic circulation to access hypothalamic nuclei via retrograde axonal transport (i.e. feedback regulation of pituitary hormones)
The primary transport mechanism in intestinal cells is active transport, utilizing carrier proteins to move nutrients against a concentration gradient into the cell. This mechanism allows for the absorption of essential nutrients like sugars and amino acids from the intestine into the bloodstream for distribution throughout the body.
Symporters are active transport mechanisms that move molecules across a cell membrane using energy from ATP or an electrochemical gradient.

Passive transport is the cellular transport mechanism. This all depends on the blood pressure.
Active transport is the type of transport mechanism that goes against the concentration gradient.

Transport Nutrients
Axonal recruitment refers to the process by which motor neurons control muscle contraction by selectively activating more or fewer muscle fibers. As the strength of a muscle contraction increases, more motor units are activated and more muscle fibers are recruited, leading to a more forceful contraction. Axonal recruitment plays a crucial role in the fine control of movements and is essential for activities that require varying degrees of force, such as lifting objects of different weights or controlling the speed and force of movements during physical activities.
Active Transport
the two types are anterograde transport and retrograde transport. anterograde is the flow of new or recycled cell products from the soma to the axon terminals for growth or regeneration in the axon. retrograde is the return from the axon terminal back to the soma so products can be degraded or recycled.
