Organelle with no defined membrane
Witryna10 kwi 2024 · Author summary Critical cellular processes require spatiotemporal regulation of sphingolipid levels among organelle membranes. Programmed cell death and inflammation, for example, are impacted by the distribution of ceramide-1-phosphate (C1P). C1P levels are specifically altered by ceramide-1-phosphate transfer protein … WitrynaThe membranous organelles are said to be fluid-filled and are generally separated from the contents of the cytoplasm through the defined membrane. The organelle ‘Endoplasmic Reticulum’ is referred to as a double membrane-bounded structure, which considered to be involved in the transferring of substances from one part of the …
