Ebe Glycolysis na-eme

Kedu ihe bụ Glycolysis?

Okwu Grik bụ́ “Glykos,” nke pụtara ụtọ (sugar), na “Lysis,” nke pụtara ikewa ma ọ bụ kewaa, bụ okwu ahụ bụ́ “glycolysis” si malite.

N'ihi ya, glycolysis (ma ọ bụ ụzọ glycolytic) bụ metabolic mbelata nke glucose, shuga nwere carbon isii, iji mepụta ume.

Ike n'ụdị adenosine triphosphate (ATP) dị mkpa maka ọrụ metabolic n'ụdị dị iche iche (dịka mmeghachi omume na-etinye aka na mkpụkọ akwara).

Ya mere, iji wepụta ike kemịkal a, glucose, isi iyi ike nke anụ ahụ, ga-agbaji site n'ọtụtụ usoro ndị a.

Usoro metabolic a na-ewepụkwa molekul abụọ nke pyruvate na NADH (nicotinamide adenine dinucleotide), na mgbakwunye na adenosine triphosphate (molecule carbon atọ).

Nke ka nke, ndị nchọpụta German Hans na Eduard Buchner, onye na-anwa imepụta ihe na-eko achịcha na-enweghị cell, chọpụtara glycolysis na 1897.

Akụkụ abụọ nke glycolysis, nke na-ewere ọnọdụ na cytoplasm ma na-akụda molekul 6-carbon nke glucose, na-eme n'ebe ahụ.

Ọzọkwa, site na usoro ihe omume, a na-ekewa glucose ụzọ abụọ phosphorylate 3-carbon molekul n'oge mbụ ogbo.

Nke ọ bụla n'ime ogige carbon atọ na-enweta oxidation na ọkwa nke abụọ, na-emepụta pyruvate na mkpụrụ ndụ abụọ nke ATP na usoro ahụ.

Ka anyị lebakwuo anya ugbu a, malite na otu molekul glucose na cytoplasm.

ogbo 1

nzọụkwụ 1

Molecule glucose anyị na-enweta phosphorylation ka ọ bụrụ glucose 6-phosphate, nke na-ejigide ọnọdụ intracellular ya na ikike mbufe phosphoryl.

Hexokinase, Enzyme, na-akpali mmeghachi omume a, nke chọrọ otu molekul nke ATP.

nzọụkwụ 2

A na-emepụta fructose 6-phosphate, glucose 6-phosphate isomer, n'oge ntụgharị nke glucose 6-phosphate.

Otú ọ dị, Fructose 6-phosphate na-adị mfe ihichapụ ebe glucose 6-phosphate adịghị, ya mere nzọụkwụ a dị oké mkpa.

Agba ọzọ nke phosphorylation na-agbanwe fructose 6-phosphate n'ime fructose 1,6-bisphosphate, nke pụtara na nsọtụ abụọ nke yinye ugbu a nwere otu phosphate jikọtara.

Site n'enyemaka nke otu molekul nke ATP, usoro a na-ejide molekul ahụ n'ọnyà ọnọdụ fructose ya.

Ebumnuche nke agba nke abụọ bụ iji usoro nke phosphorylation oxidative iji gbanwee mkpụrụ ndụ GAP abụọ anyị ka ọ bụrụ pyruvate.

Anyị ga-emecha ọkwa nke abụọ otu molekul GAP n'otu oge iji dobe ihe n'ụzọ kwụ ọtọ.

Ka anyị maliteghachi na nzọụkwụ isii ndị a;

nzọụkwụ 6

A na-agbanwe mkpụrụ ndụ GAP ọ bụla ka ọ bụrụ 1,3-Bisphosphoglycerate na nzọụkwụ a. Enwere ike itinye nke a na 1,3-BPG.

Nke ka nke, a na-emepụta 1,3-BPG n'ihi na otu phosphate nke e hibere nso nso a nwere ikike dị ịrịba ama maka mbufe phosphoryl. Njikọ a ga-ahapụ ike ma ọ bụrụ na agbajiri ya.

Otu molekul NADH, ihe na-ebu elektrọn ike dị elu nke enwere ike iji rụpụta ATP ma emechaa. n'oge iku ume cellular, A na-emepụtakwa na usoro yana 1,3-BPG.

nzọụkwụ 7

Site na iwepu molekul phosphate site na 1,3-BPG ma tinye ya na 3-phosphoglycerate, 1,3-BPG na-agbanwe ghọọ 3-phosphoglycerate.

Ọzọkwa, a na-emepụta ike site na ọrụ a n'ụdị otu molekul ATP.

nzọụkwụ 8

A na-emepụta molecule phosphoglycerate ọzọ na-agba ume mgbe 3-phosphoglycerate na-agbanwe ghọọ 2-phosphoglycerate.

nzọụkwụ 9

A na-emepụta Phosphoenolpyruvate, mgbe ụfọdụ a na-akpọ PEP, site na 2-phosphoglycerate.

Ka ọ dị ugbu a, ihe a nwere ike dị elu ma bụrụ nke a na-ejighị n'aka, na-agbanwe ngwa ngwa na pyruvate na usoro ọzọ.

nzọụkwụ 10

Ihe njedebe nke glycolysis bụ pyruvate, nke a gbanwere site na PEP.

Karia, maka ngụkọta nke mkpụrụ ndụ ATP abụọ maka usoro nke abụọ nke usoro na glycolysis n'ozuzu ya, usoro ntụgharị a na-emepụta otu molekul ATP ọzọ.

Nke a mechiri ọkwa nke abụọ maka molekul GAP mbụ, agbanyeghị, ọkwa nke mbụ mepụtara mkpụrụ ndụ GAP abụọ, yabụ buru nke ahụ n'uche.
