Indlela Yokusebenza Ye-Insulin Receptor: I-insulin iyi-hormone ye-peptide edlala indima ebalulekile ekugcineni amazinga kashukela egazini alinganiselayo kanye nokulawula i-carbohydrate, amafutha, kanye ne-protein metabolism. Ukuze i-insulin isebenze, idinga "i-portal" ebusweni beseli engakwazi ukubona nokuhumusha izimpawu ze-insulin zibe impendulo yezinto eziphilayo. Lesi sikhungo sokungena yi-insulin receptor. Ukuqonda indlela yokusebenza… Funda kabanzi

Umsebenzi we-Myoglobin Ekugcinweni Kwe-Oxygen Yemisipha I-Myoglobin iyiprotheni ebalulekile emzimbeni womuntu nowesilwane, ehlotshaniswa kakhulu nekhono lemisipha lokusebenza kahle. Le protheni yaziwa ngokuthi "isitolo se-oxygen" ezicutshini zemisipha. Indima yayo iba ebalulekile lapho imisipha idinga amandla amaningi, njengalapho uzivocavoca, ugijima, ubhukuda, noma eminye imisebenzi yomzimba... Funda kabanzi

Izinzuzo Zokuhamba Ngempilo Yamathambo Ukuhamba ngezinyawo kuyindlela elula, eshibhile, futhi elula kakhulu cishe kunoma ubani. Nakuba kungase kubonakale kulula, ukuhamba kunomthelela omkhulu empilweni iyonke, okuhlanganisa nempilo yamathambo. Amathambo akuzona izinto "ezingaphili" okucatshangwa ukuthi ziyizo. Ziyizicubu eziphilayo ezakhiwa futhi zivuselelwa njalo. Umkhuba… Funda kabanzi

Ukubaluleka Kwama-Lipase Enzymes Ekugayweni Kwamafutha Amafutha avame ukuba nomthelela omubi ngoba ahlotshaniswa nokukhuluphala kanye nezifo ezithile. Kodwa-ke, amafutha ayi-macronutrient ebalulekile emzimbeni. Amafutha asebenza njengomthombo wamandla okusekelayo, ingxenye yama-membranes eseli, avikela izitho zomzimba, futhi asiza ekumuncweni kwamavithamini ancibilikayo amafutha njengevithamini A, D, kanye no-E. … Funda kabanzi

Imiphumela Ye-Hypothyroidism Ku-Metabolism I-Hypothyroidism yisimo lapho i-thyroid gland ingakhiqizi ama-hormone e-thyroid anele ukuhlangabezana nezidingo zomzimba. Ama-hormone e-thyroid—ikakhulukazi i-thyroxine (T4) kanye ne-triiodothyronine (T3)—adlala indima ebalulekile ekulawuleni i-metabolism, inqubo yomzimba yokuguqula ukudla kube amandla kanye “nezinto zokusetshenziswa” zokukhula nokulungiswa kwamaseli. Ngakho-ke, lapho kukhiqizwa ama-hormone… Funda kabanzi

Kungani i-ATP Ibalulekile Ku-Metabolism Ezintweni eziphilayo, i-metabolism iwuchungechunge lwezinqubo zamakhemikhali eziqhubekayo ezigcina impilo. I-Metabolism ihlanganisa amaqembu amabili amakhulu: i-catabolism (ukuwohloka kwama-molecule ukuze akhiqize amandla) kanye ne-anabolism (ukuhlanganiswa kwama-molecule ayinkimbinkimbi adinga amandla). Ngemuva kwazo zonke lezi zindlela zokusabela, kukhona "uhlobo lwemali lwamandla" olulodwa oludlala indima ebalulekile kakhulu:… Funda kabanzi

Isakhiwo kanye Nomsebenzi we-Mitochondria I-Mitochondria yi-organelles ebalulekile etholakala cishe kuwo wonke amaseli e-eukaryotic (amaseli ezilwane, izitshalo, isikhunta, kanye namaseli e-protist). Lawa ma-organelle avame ukubizwa ngokuthi "amandla amakhulu" eseli ngenxa yendima yawo ebalulekile ekukhiqizeni amandla ngesimo se-ATP (i-adenosine triphosphate). Kodwa-ke, i-mitochondria ingaphezu nje kwezinjini zamandla. Iphinde ihileleke ezinqubweni ezibalulekile ezahlukahlukene, njenge... Funda kabanzi

Umsebenzi we-Pepsin Enzyme ekugayweni kwamaprotheni Ukugaya amaprotheni kuyinqubo ebalulekile ohlelweni lokugaya ukudla lomuntu ngoba idlala indima enkulu ekwakhekeni nasekulungiseni izicubu, ekwakhekeni kwama-enzyme nama-hormone, nasekulondolozeni uhlelo lokuzivikela komzimba. Ukuze umzimba usebenzise amaprotheni okudla, kumele ahlukaniswe abe ama-molecule alula, ikakhulukazi ama-peptide, futhi ekugcineni… Funda kabanzi

Ukubaluleka kwe-Iodine Ekukhiqizweni kwama-hormone e-thyroid I-Iodine iyiminerali ebalulekile evame ukunganakwa, kodwa idlala indima ebalulekile emzimbeni womuntu. Omunye wemisebenzi eyinhloko ye-iodine isithako esiyinhloko ekwakhiweni kwama-hormone e-thyroid, okuyi-thyroxine (T4) kanye ne-triiodothyronine (T3). Lawa ma-hormone amabili alawula izinqubo eziningi ezibalulekile, kusukela ekusetshenzisweni kwamandla kuya ekukhuleni… Funda kabanzi

Kungani i-Fibrinogen Ibalulekile Ekuvimbeni Kwegazi Ukuvimbezeleka kwegazi kuyindlela ebalulekile yokuzivikela yomzimba ukuze uyeke ukopha lapho kwenzeka ukulimala. Ngaphandle kohlelo lokuvimbezeleka olusebenza kahle, ngisho nokulimala okuncane kungaba yingozi njengoba igazi liqhubeka nokuvuza ngokungalawuleki. Ngemuva kwale nqubo ebonakala ilula kukhona uchungechunge oluyinkimbinkimbi lwezimpendulo zamakhemikhali ezibandakanya eziningi… Funda kabanzi
