Otu Enzymes si arụ ọrụ: Ikpughe ihe nzuzo nke ihe ndị na-akpalite ihe ndị dị ndụ
Enzymes bụ ụdị protein nke na-arụ ọrụ dị ka ihe na-akpali mmeghachi omume kemịkalụ dị ndụ. Na-enweghị enzymes, ọtụtụ mmeghachi omume dị mkpa na ihe ndị dị ndụ ga-eme nwayọ nwayọ iji kwado ndụ. N'isiokwu a, anyị ga-atụle otu enzymes si arụ ọrụ, site na nhazi ha ruo na usoro ọrụ ha, na-eme ka mmeghachi omume bayoloji mee ihe n'ụzọ dị elu.
Nhazi na Nhazi nke Enzyme
Enzymes bụ isi ihe mejupụtara protein, nke bụ polymers nke amino acid. Dịka protein ndị ọzọ, enzymes nwere nhazi atọ kpọmkwem. E kewara nhazi a n'ọkwa anọ: praịmarị, nke abụọ, nke atọ, na nke anọ.
– Nhazi Mbụ: Nke a bụ usoro ahịrị nke amino acid nke edobere n'ụzọ pụrụ iche dabere na koodu mkpụrụ ndụ ihe nketa.
– Nhazi nke Abụọ: Nhazi nke ụkpụrụ dịka alpha helices na mpempe akwụkwọ beta, nke a na-emepụta site na njikọ hydrogen n'etiti isi agbụ amino acid.
– Nhazi nke atọ: Ọdịdị protein dị mgbagwoju anya na nke nwere akụkụ atọ kpọmkwem, nke mmekọrịta dị n'etiti agbụ amino acid na-eme ka ọ dị mfe.
– Nhazi nke Quaternary: Ụfọdụ protein nwere nhazi nke Quaternary, nke bụ ihe mgbagwoju anya nke e guzobere n'etiti polypeptides abụọ ma ọ bụ karịa.
Enzymes nwekwara ebe na-arụ ọrụ, ebe kpọmkwem ebe substrate (molekul reactant dị na mmeghachi omume enzyme-catalyzed) ga-ejikọta. Ebe a nwere ọdịdị na ihe onwunwe kemịkalụ kpọmkwem nke dabara na substrate ahụ, dịka igodo si adaba na mkpọchi.
Usoro Ọrụ Enzyme
Enzymes na-arụ ọrụ site n'ibelata ike mkpali achọrọ iji malite mmeghachi omume kemịkalụ. Mmeghachi omume kemịkalụ ọ bụla chọrọ oke ike iji malite. N'ime usoro ihe ndị dị ndụ, ike a na-adịkarị oke elu, yabụ a chọrọ enzymes iji belata ya. Lee usoro izugbe:
1. Njikọta nke Substrate: Ihe mejupụtara ya na-ejikọ na ebe enzyme ahụ na-arụ ọrụ, na-emepụta mgbagwoju anya nke enzyme-substrate. Njikọ a nwere ike ibute mgbanwe nhazi na enzyme a maara dị ka "njikọ nke induced fit." Mgbanwe a na-eme ka mmekọrịta dị n'etiti enzyme na substrate dịkwuo mma.
2. Ibelata Ike Mmegharị Ahụ: Site na njikọ nke substrate, enzyme ahụ na-eme ka ọnọdụ mgbanwe ahụ sie ike, nke bụ usoro nwa oge n'oge mmeghachi omume nke nwere ike kachasị elu. Enzyme ahụ na-enye ụzọ ọzọ nwere ike imegharị ahụ dị ala, si otú a na-eme ka mmeghachi omume ahụ dị ngwa.
3. Nhazi Ngwaahịa: Mgbe mmeghachi omume ahụ gasịrị, enzyme ahụ na-akwado mgbanwe nke substrate ahụ ka ọ bụrụ ngwaahịa. Enzyme ahụ na-ewepụta ngwaahịa ahụ wee dị njikere ijide molekul substrate ọzọ.
Ụdị Enzymes Dabere na Ọrụ
A na-ekewa enzyme dịka ọrụ ha si dị, ọtụtụ n'ime ha na-adaba na nhazi ndị a:
– Oxidoreductase: Na-eme ka mmeghachi omume mbelata oxidation, nnyefe elektrọn n'etiti molekul dị mfe.
– Transferase: Na-ebufe otu ọrụ site na otu molekul gaa na nke ọzọ.
– Hydrolase: Na-agbaji njikọ molekul site na itinye mmiri.
– Lyasis: Ịkụji njikọ site na ihe ndị ọzọ na-abụghị hydrolysis ma ọ bụ oxidation, nke na-ebutekarị njikọ abụọ.
– Isomerase: Na-agbanwe nhazi nke atọm n'ime molekul.
– Ligase: Na-ejikọta molekul abụọ site n'ịmepụta njikọ kemịkalụ ọhụrụ, ọtụtụ mgbe na njikọta ATP hydrolysis.
Ihe Ndị Na-emetụta Ọrụ Enzyme
Ihe dị iche iche gburugburu ebe obibi nwere ike imetụta ọrụ enzyme, gụnyere:
– pH: Ọtụtụ enzymes na-egosipụta ọrụ kacha mma n'ime oke pH akọwapụtara. Mgbanwe na pH nwere ike imetụta nhazi nke enzyme ahụ, ọkachasị na ebe ọrụ.
– Okpomọkụ: Ọrụ enzyme na-abawanye ka okpomọkụ na-arị elu ruo oke ụfọdụ, mgbe nke ahụ gasịrị, nhazi enzyme ahụ nwere ike imebi (denaturation).
– Ntinye nke ihe dị n'ime ala na Enzyme: Ọrụ na-abawanye ka mmụba nke ihe dị n'ime ala na-abawanye ruo mgbe enzyme niile jikọtara na ihe dị n'ime ala. Enwere ike ịbawanye ọrụ enzyme site na ịbawanye ọnụọgụ enzyme.
– Ihe mgbochi na ihe na-eme ka ihe rụọ ọrụ: Ụfọdụ molekul nwere ike igbochi ma ọ bụ mee ka ọrụ enzyme ka mma. Nke a nwere ike ịbụ asọmpi, enweghị asọmpi, na allosteric.
