It occurs on its own without the input of energy. Intracellular transport is an essential process for cellular functions and is driven by molecular motors. Kinesin superfamily proteins (KIFs) are a major superfamily of molecular motors that use the microtubule cytoskeleton. KIFs are encoded by more than 45 genes and perform fundamental functions that are necessary for life.

The endoplasmic reticulum is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits – rough endoplasmic reticulum, and smooth endoplasmic reticulum. The endoplasmic reticulum is found in most eukaryotic cells and forms an interconnected network of flattened, membrane-enclosed sacs known as cisternae, and tubular structures in the SER. The membranes of the ER are Ans: In a normal cell, membrane transport is vital for the movement of glucose and amino acids into the cells for the production of energy and protein synthesis,, respectively. In the nerve cell, the conduction of nerve impulses occurs by polarization, depolarization, and repolarization process. The electron transport system consists of hydrogen carrier complexes, electron carriers and an ATP synthase ion channel. ETS creates a chemiosmotic gradient, which allows the diffusion of protons into the matrix by the production of ATP. The ATP is harnessed by the cell to perform cellular and metabolic activities.

Microtubules are one of the cytoskeletal filament systems in eukaryotic cells. The microtubule cytoskeleton is involved in the transport of material within cells, carried out by motor proteins that move on the surface of the microtubule. Microtubules are very important in a number of cellular processes.

Lymph containing large amounts of absorbed lipid is called chyle (k ı̄ l; milky lymph). The lymphatic system carries the chyle to the bloodstream. For an organism to function, substances must move into and out of cells.
Proteins synthesized in the cytosol are distributed to their respective organelles, according to their specific amino acid’s sorting sequence.

and is involved in moving materials around within the cell. Molecular motors are specialized proteins that bind to a variety of organelles, referred to as cell cargo, and transport them along microtubule filaments (structural proteins commonly referred to Transport in Cells: Diffusion and Osmosis | Cells | Biology | FuseSchoolIn this video we are going to discover how cells take in useful substances and remove an organelle that synthesizes and transports lipids.

Proteins synthesized in the cytosol are distributed to their respective organelles, according to their specific amino acid’s sorting sequence. Within a system, there will be different rates of diffusion of the different substances in the medium. Factors That Affect Diffusion.
