Ohograde axonal transpo involves all except
**Core Concept**
Ohograde axonal transport is a process by which molecules are transported along the axon of a neuron from the cell body to the axon terminals. This process is essential for the delivery of proteins, lipids, and other essential molecules to the axon terminals, where they are required for neurotransmission and maintenance of axonal function.
**Why the Correct Answer is Right**
Ohograde axonal transport involves the movement of molecules through the axoplasm, a complex network of microtubules and motor proteins. The key motor protein involved in this process is kinesin, which binds to the microtubules and moves along them, carrying the molecules with it. This process is essential for the delivery of synaptic vesicles, neurotransmitter receptors, and other essential molecules to the axon terminals.

**Clinical Pearl / High-Yield Fact**
It's essential to note that anterograde axonal transport is disrupted in certain neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS) and Alzheimer's disease. This disruption can lead to the accumulation of toxic proteins and the degeneration of axons, contributing to the pathogenesis of these diseases.
**Correct Answer:** D.
