WebThe chemical equation that correctly summarizes the overall reaction in oxidative phosphorylation is A) H2 + O2 → H2O + O. B) 2 H2 + O2 → 2 H2O. C) 3 H2 + 2O2 → 3 H2O + 2 O. D) H2 + O2 → H2O. E) P + 3 O → PO3. B The function of the citric acid cycle is to A) remove hydrogen atoms from organic molecules and transfer them to coenzymes. WebIn gluconeogenesis, organisms use ATP to make glucose, then in cellular respiration they break down the glucose again to get energy. Why not just store the ATP? A. ATP does not have high-energy bonds. B. ATP is not energy dense enough. C. ATP only has energy after it is activated by glucose. D. ATP only has energy when it is attached to glucose.

Web2 ATP and 2 NADH. Strategies of glycolysis: -Form phosphorylated intermediates G6P and F6P using ATP as phosphate donor. - Convert phosphorylated int. to compounds with high energy phosphate bonds. - Couple the cleavage of high-E phosphate bonds to the synthesis of ATP. Glucose --> Glucose-6-phosphate. hexokinase. WebNov 25, 2015 · The additional ATP occurs if one considers the total energetic cost of the aminoacylation reaction as 2 ATP, not 1 ATP. This arises from the fact that the ATP is hydrolysed to AMP (+PPi) and not ADP. Recycling of the AMP involves first the use of 1 molecule of ATP in the adenylate kinase reaction to produce ADP: ATP + AMP ⇄ 2ADP
WebSo to put this in context with glycolysis and gluconeogenesis above, it turns out that ATP is actually a big allosteric regulator of one of these two pathways. So recall that gluconeogenesis requires ATP, a net amount of ATP, to produce glucose. It's an anabolic building up pathway. WebGluconeogenesis is the synthesis of glucose. It is basically glycolysis run backwards; three new reactions (involving four new enzymes) make the standard free energy favorable. For every molecule of glucose synthesized from two molecules of pyruvate, 4 ATP, 2 GTP, and 2 NADH are used.
Web2. All gluconeuogenesis precursors must be converted to OAA for the process. In glycolysis: PEP is converted to pyruvate by pyruvate kinase in an irreversible reaction. So in gluconeogenesis: conversion of pyruvate-->PEP consists of two steps: 1a. Pyruvate-->oxaloacetate (OAA) by pyruvate carboxylase. **1b. WebThere are 14 enzymes involved in the conversion of lactate into glucose; three of these enzymes are classified as gluconeogenic (PEPCK, fructose-1,6-bisphosphatase (FBPase), and glucose-6-phosphatase (G6Pase)) and one is anaplerotic (PC), since it is important in both gluconeogenesis and lipogenesis.

In gluconeogenesis the conversion of pyruvate to PEP, the conversion of fructose-1,6-bP, and the conversion of glucose-6-P to glucose all occur very spontaneously which is why these processes are highly regulated. how to stop screen sharing on laptopThe gluconeogenesis pathway is highly endergonic until it is coupled to the hydrolysis of ATP or GTP, effectively making the process exergonic. For example, the pathway leading from pyruvate to glucose-6-phosphate requires 4 molecules of ATP and 2 molecules of GTP to proceed spontaneously. See more Gluconeogenesis (GNG) is a metabolic pathway that results in the generation of glucose from certain non-carbohydrate carbon substrates.
