Based on your residing of this chapter, what would you expect to be the most immediate effect oil glycolysis, if the steady-state concentration of gJucose-6-P were 8.3 mM instead of 0.083 mM?
Please answer as many as possible 1. Substrate regulation of glycolysis and citric acid cycle (fructose-2,6-bisphosphate, fructose-1,6-bisphosphate, ADP, AMP-positive effectors of glycolysis enzymes; ATP, citrate, NADH, acetyl-CoA-negative effectors of glycolysis enzymes; ADP, AMP-positive effectors of citric acid cycle enzymes; ATP, NADH-negative effectors of citric acid cycle enzymes). 2. The role of the liver in the regulation of glucose concentration. 3. Hormonal regulation of glucose metabolism (the influence of epinephrine, glucagon, glucocorticoids, ACTH, STH, the central role of insulin in regulation of glucose metabolism). 4. Peculiarities of carbohydrate metabolism in the liver and muscles. 5. Peculiarities of carbohydrate metabolism in tumor cells.
Long explanations are NOT NEEDED. Answer only d and e. ATP accounting. Consider 1 molecule of the sucrose (monomeric units: glucose and fructose) that will undergo complete oxidation. -Number of pyruvate molecules after glycolysis is 4.-Net ATP produced in glycolysis only (via substrate-level phosphorylation) is 2.-Number of NADH produced using the pyruvate dehydrogenase complex reaction is 1. Now find:d. Number of NADH and FADH2 produced from Krebs cycle.e. Net ATP produced (complete oxidation via Malate aspartate shuttle).
The pathway that converts glucose to acetyl-CoA is often referred to as an “aerobic oxidation pathway.” (a) Is molecular boxygen involved in any of the steps of glycolysis? (b) Thinking back to Chapter 20, where does molecular oxygen enter the picture?
Multiple Choice: A. Glycolysis “uses” ATP by: Reducing CO2 Substrate-level phosphorylation Anabolism Oxidative phosphorylation B. Labels glucose for glycogenesis. GTP ATP CTP UTP C. The enzymes involved in the anaerobic reactions of pyruvate are (naka checkbox, so pwede more than one it answer) Releases energy by producing ATP Coenzymes act as oxidizing agents for the oxidation of metabolites Examples are glycolysis, PPP, & photosynthesis Breakdown of larger molecules into smaller ones
Please answer yes or no and give a short explanation. Thank you 1. The rate of glycolysis and glycogenolysis is controlled by phosphofructokinase. 2. Glycogen in the muscles falls with the formation of glucose-6-phosphate. 3. Is the process of anaerobic glycolysis accompanied by accumulation of NADH (H +)?
Explain why gluconeogenesis is not the mere reversal of glycolysis. Give at least 3 reasons to support your answer. The answer must include the terms; endergonic, exergonic, reciprocal regulation, and futile cycle.
