endoplasmic reticulum
Endoplasmic reticulum is the organelle composed of a series of channels throughout the cytoplasm. It functions in the transport of molecules, synthesis of lipids and proteins, and regulates calcium levels in the cell.
The endoplasmic reticulum is called the "transport system" of the cell because it is responsible for the synthesis, processing, and transport of proteins and lipids within the cell. It is a network of membranes that helps transport molecules from one part of the cell to another, ensuring that proteins and other important molecules are delivered to their correct destinations.
The endoplasmic reticulum moves substances through the cell within channels made of membranes. The cytoplasm also moves substances and organelles through cytoplasmic streaming
The channels that transport sodium and potassium within the axon are called voltage-gated sodium channels and voltage-gated potassium channels. These channels play a crucial role in generating and propagating action potentials along the axon.

Selective transport refers to the movement of specific substances across a membrane, such as a cell membrane or an organelle membrane, through specialized transport proteins or channels. This process allows cells to regulate the passage of certain molecules in and out of the cell, maintaining internal homeostasis. Selective transport ensures that only certain molecules are allowed to cross the membrane, while others are excluded.
The sarcoplasmic reticulum are the membranous interconnecting channels and sacs that surround and run parallel to the myofibrils.
Endoplasmic reticulum is the organelle composed of a series of channels throughout the cytoplasm. It functions in the transport of molecules, synthesis of lipids and proteins, and regulates calcium levels in the cell.
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
