By spreading throughout the cell (in the cytoplasm), the cytoskeleton helps maintain the shape of the cell while also ensuring its elasticity.
Also known as the powerhouse, mitochondria play an important role in respiration where they generate ATP (adenosine triphosphate) from substrates in the presence of oxygen.
Using their DNA, mitochondria are able to encode for some of the components they require to perform their functions.
The origin of most lipids imported into mitochondria is the endoplasmic reticulum, which requires interaction of these two subcellular compartments.
Recently, protein complexes that are involved in membrane contact between endoplasmic reticulum and mitochondria were identified, but their role in lipid transport is still unclear.
Ribosomes are tiny organelles that contain RNA and specific proteins within the cytoplasm.
Within the cell, ribosomes are directly involved in the manufacture of proteins by using their RNA and amino acids.
On the other hand, the rough ER is involved in the production of antibodies, insulin as well as transportation of proteins into the smooth ER.
A lysosome is commonly referred to as sacs of enzymes.
They protect the cell from external influences, organize the interior in distinct compartments and allow balanced flux of components.
Besides their specific proteome, organelles exhibit unique lipid compositions, which influence their shape, physical properties, and function.
