lipid synthesis is a primary function of which organelle
Endomembrane system Most lipids are synthesized in yeast either in the endoplasmic reticulum, lipid particles, or the mitochondrion, with little or no lipid synthesis occurring in the plasma membrane or nuclear membrane.[12][13] Sphingolipid biosynthesis begins in the endoplasmic reticulum, but is completed in the Golgi apparatus.[14] The situation is similar in mammals, with the exception of the first few steps in ether lipid biosynthesis, which occur in peroxisomes.[15] The various membranes that enclose the other subcellular organelles must therefore be constructed by transfer of lipids from these sites of synthesis.[16] However, although it is clear that lipid transport is a central process in organelle biogenesis, the mechanisms by which lipids are transported through cells remain poorly understood.[17]
Rate equation k is the first order rate constant, which has units of 1/s or sâˆ’1.
Nuclear membrane Exactly how the nuclear membrane reforms during telophase of mitosis is debated. Two theories exist[7]â€”
