Glucose, GLYCOSIS, gluconeogenesis - Coggle Diagram
Glucose
utilization for four major pathways
energy production
藉由堂分解(代謝)產生高能物質(eg. ATP, NADH)

pathway
GLYCOSIS
-
-
glycolysis
-
payoff phase(產生能量)
-
-
step7:1st產生ATP(1,3BPG→3PG)
1,3BPG是高能化合物(提供C1上的phosphate group給ADP以形成ATP)
-
-
-
-
step10:2nd產生ATP(PEP→Pyr)
-
-
-
favorable/irreversible [單向:調控點] (被ATP, 二價金屬及其他代謝物調節)
-
step6:GAP的氧化( G3P→1,3BPG)
-
詳細反應
-
thiohemiacetal被NAD+氧化:NAD+會去抓電子使與S接合的G3P碳的碳氧單鍵變雙鍵,然後G3P就成了一個酵素附著(enzyme-bound)的硫酯(thioester),而NAD+轉為NADH + H+
