Question

Accepted Answer

∻Answer∻ ⚹ The amount of fumarate produced in the urea cycle is used to generate ATP in the mitochondria, which can then be used for gluconeogenesis. ⚹ ∻Solution∻ ‖ a ⋮ Fumarate production in the urea cycle: Fumarate is generated in the urea cycle when argininosuccinate is cleaved into arginine and fumarate. ‖ ‖ b ⋮ Conversion of fumarate to malate: Fumarate is transported into the mitochondria where it is hydrated to form malate by the enzyme fumarase. ‖ ‖ c ⋮ Malate to oxaloacetate conversion: Malate is then oxidized to oxaloacetate by malate dehydrogenase, producing NADH. ‖ ‖ d ⋮ ATP generation: The NADH produced can enter the electron transport chain to ultimately generate ATP. ‖ ‖ e ⋮ Gluconeogenesis utilization: The oxaloacetate can be used as a substrate for gluconeogenesis to form glucose. ‖ ∻Key Concept∻ ⚹ The urea cycle and gluconeogenesis are interconnected metabolic pathways, with fumarate linking the two. ⚹ ∻Explanation∻ ⚹ Fumarate produced in the urea cycle can be used to generate ATP, which is necessary for gluconeogenesis, thus connecting the energy requirements of both processes. ⚹◊What is the role of fumarate in the urea cycle and gluconeogenesis in terms of ATP formation?⍭ Generate me a similar question◊
