Why do cells divide? Why are B cells important? Infer why whitefish embryo cells and root-tip cells are used to study mitosis instead of cells in a human bone or plant leaf. Why do lipids make effective cell membranes in living cells?
Why do cells need selectively permeable membranes? What is the plasma membrane of a cell and what is the function of the plasma membrane? How is osmosis different with a semipermeable and permeable membrane? Why proteins are an excellent macromolecule for anchoring in the plasma membrane?
this is arguably one of thebiggest nutritional mythsout there. Asians enjoy soy in its fermented state and in considerably smaller quantities than we do.
“The adjuvanted effect of mRNA-based vaccine is delivered primarily by ionizable lipids in the LNP,” said senior author Elias El Haddad, PhD, a professor in the College of Medicine. “We found that empty LNPs, those with no mRNA, stimulate dendritic cell matura...
Given that acne commonly affects patients around the mouth, this has been interpreted as evidence of some unmet oral need. However, the potent effectiveness of isotretinoin, a retinoid that significantly reduces sebum production and is generally considered the most powerful treatment for acne but has...
It was speculated that peroxisomes may be needed at the division plane to remove hydrogen peroxide or to recycle membrane lipids [28]. The positioning could also contribute to an equal partitioning of peroxisomes to the daughter cells [28], [93]. Nevertheless, the accumulation of peroxisomes ...
can be essential, non-essential or conditional. Non-essential and conditional amino acids are made in your system, so you do not need to worry about consuming them each day. Knowing which foods provide all or some of the essential amino acids helps you make sure your body gets adequate amou...

Petroleum's main components come from lipids that were first assembled long ago in those organisms' cells. So the question is, if petroleum-derived plastic comes from biomaterial, why doesn't it biodegrade? A crucial manufacturing step turns petroleum into a material unrecognized by the organisms ...
Why do mitochondria and chloroplasts have 2 bilayer lipids around them? Do prokaryotic cells have mitochondria? If so, what is the purpose of the mitochondria? Why is the cell membrane important to homeostasis? Why do cells need carrier proteins that transport glucose?
