Njengoba kunikezwe isigaba esilandelayo esithinta ukwakheka kwamangqamuzana, yiziphi izibonelo zamaprotheni e-membrane?
Context:Ingqamuzana ngayinye ihlanganiswe ulwelwesi lweseli oluhlukanisa i-cytoplasm yayo nendawo engaphandle kweseli. Ulwelwesi lweseli luqukethe i-lipid bilayer, kuhlanganise nama-cholesterol ahlala phakathi kwama-phospholipids ukuze alondoloze uketshezi lwawo emazingeni okushisa ahlukahlukene. Izindwangu zamangqamuzana ziyakwazi ukungena, zivumela ama-molecule amancane anjengomoya-mpilo, i-carbon dioxide namanzi ukuba adlule kuyilapho zivimbela ukunyakaza kwama-molecule amakhulu nezinhlayiya ezinama-ion. Izindwangu zamangqamuzana ziqukethe namaprotheni e-membrane, kuhlanganise namaprotheni e-membrane ahlanganisiwe ahamba ngaphesheya kwe-membrane asebenza njengabathwali be-membrane, namaprotheni angaphandle anamathela kancane ohlangothini lwangaphandle lwe-membrane yeseli, asebenza njengama-enzyme akha iseli. Izindwangu zamangqamuzana zibandakanyeka ezinqubweni ezihlukahlukene zamangqamuzana ezinjengokunamathelana kwamangqamuzana, ukugcina amandla kagesi, nokuthumela imiyalezo kwamangqamuzana futhi zisebenza njengendawo yokunamathisela izakhiwo eziningana ezingaphandle kwamangqamuzana ezinjengodonga lwamangqamuzana, i-glycocalyx, ne-cytoskeleton.
Isibonelo esisodwa samaprotheni e-membrane amaprotheni e-membrane ahlanganisiwe ahamba ngaphesheya kwe-membrane futhi asebenza njengabathwali be-membrane.
