The cell akpụkpọ ahụ na ya ndu ọrụ

Ugbu a, n'ihi na ọtụtụ ndị na ọ bụ ọ bụla na nzuzo na membranes bụ a-eme ihe ụkpụrụ nke Biochemical Filiks ke cell. N'ihi ndu membranes-akwado site na esịtidem homeostasis n'ime cell. Cell akpụkpọ ahụ vysokoizberatelno eji ọsọ nke penetration nke dị iche iche ndu ogige n'ime cell, nakwa dị ka ụzọ nke enzymes na ụgbọala. Ọzọkwa, a na Ọdịdị nwere a mgbagwoju ndu mgbagwoju nke na-enye nghọta, mgbanwe na nyefe nke ọmụma si na gburugburu ebe obibi n'ime cell.

The cell akpụkpọ ahụ bụ a Ọdịdị nke ekwe sel subcellular organelles (lysosomes, mitochondria, Golgi ngwa , wdg). Onye ọ bụla cell bụ a holistic usoro membranes wuru na tubular, na akpa na tankị. The ndu akpụkpọ - na mkpa efere (60-70%) glycoprotein na lipoprotein okike. Ọ ga-kwuru na nje na osisi sel , n'adịghị ka ụmụ anụmanụ na-enweghị ike ịgbanwe ha udi dị ka ha na-gburugburu a oké cell mgbidi. Cell akpụkpọ ahụ osisi ahụ mejupụtara polysaccharides, bacteria nke monosaccharides, amino ilekwata shuga, lipids na amino asịd.

Ọdịdị nke ahụ cell akpụkpọ ahụ.

The isi mmiri nke cell membranes na-lipids (60-70%) - phosphatidylcholine, phosphatidylethanolamine, sphingomyelin na cholesterol. Cholesterol bụ mmasị na ndu akpụkpọ ahụ rigidity, otú ahụ akpụkpọ ahụ na a obere ịta nke cholesterol ọzọ na-agbanwe. akpụkpọ ahụ na-edozi na-ọkọnọ lipoprotein na glycoprotein okụre (30-35%). Cell akpụkpọ ahụ na a obere ego nwekwara carbohydrates dị ka akụkụ nke glycoproteins, glycolipids na glycosaminoglycans (5-10%). Ọdịdị nke cell membranes na-adị obere ogige (nucleic asịd, antioxidants, inorganic ion, coenzymes, wdg). Plasma akpụkpọ ahụ na-anya yiri na na-integral na intracellular membranes nke endoplasmic reticulum (reticulum). The mejupụtara agụnye reticulum akpụkpọ ahụ granular na agranular endoplasmic reticulum, nke kewaa n'ime ohere n'ime a plurality nke cell compartments. Ọ dị mkpa nke ukwuu na ụkpụrụ nke intracellular iga nke bekee na eruba nke metabolic n'ibu.

The ọrụ nke cell akpụkpọ ahụ.

Cell membranes enye a mgbochi ọrụ, nke na-egosipụta onwe n'ụdị nhọrọ, na-achịkwa metabolism na gburugburu ebe obibi. Site nhọrọ permeability n'ime a cell nwere ike tinye na bekee nke a ụfọdụ size.

Biomembrane iga ọrụ na-enye nyefe nke nri n'ime cell na mwepụ nke ikpeazụ metabolites ya nime ya. The cell akpụkpọ ahụ na-aka na ịnọgide na-enwe ezigbo onye Onyenwe anyị +.

Matriks akpụkpọ ahụ ọrụ mere site ụfọdụ interposition na ikuziri nke akpụkpọ ahụ na-edozi. Ịrịba ama ọrụ na huu n'ibu ọrụ nwere cell mgbidi, na ụmụ anụmanụ - intercellular umi. The ihe nnabata ọrụ a rụrụ n'ihi ọnụnọ nke pụrụ iche na-edozi ahụ na-metụtara nanị akụkụ ụfọdụ na cell akpụkpọ ahụ.

The enzymatic ọrụ nke ndu membranes metụtara na akpụkpọ ahụ na-edozi na enzymes. Ka ihe atụ, plasma membranes nke epithelial mkpụrụ ndụ (epithelial sel nke eriri afọ) nwere digestive enzymes.
