Regulation of glycolysis under given conditions:-
At low ATP :- Rate of glycolysis increase
At High ATP :- Glycolysis is inhibited by increasing ATP
At increased insulin :- as insulin increases glycolysis rate also increases to lower the blood sugar level.
At low blood sugar levels :- the rate of glycolysis process is comparatively slower than normal.
Q2: HOW IS GLYCOLYSIS REGULATED UNDER THESE CONDITIONS? LOW ATP HIGH AΤΡ INCREASED INSULIN LOW BLOOD...
How does the level ATP and NADH affect glycolysis and TCA cycle? I know the high levels of ATP will slow down glycolysis, and that low ATP levels will activate it. But does NADH inhibit glycolysis too? Also, how do ATP/NADH levels affect the TCA cycle? Thank you!
Match: Diabetes Type I (IDDM) Lack of insulin produced [Choose) Insulin Acts to decrease blood sugar when levels are high Lack of insulin produced Glucagon Too much insulin produced Cells resistant to the insulin message Diabetes Type II (NIDDM) Acts to increase blood sugar levels when low Hypoglycemia [Choose)

Under increased concentrations of glucose 6-phosphate, the rate of glycolysis ___________. Increases Decreases Stays the same Under increased concentrations of ATP, the rate of glycolysis __________. Increases Decreases Stays the same
25. Glucagon is a hormone released by the pancreas in response to low blood glucose levels. It can stimulate a pathway that regulates flux through glycolysis and gluconeogenesis. Explain the steps involved in this pathway (beginning with glucagon binding to its receptor) and explain exactly how flux through glycolysis and gluconeogenesis are regulated in response to glueagon
3. Under conditions of hypoglycemia, the hormone glucagon is released, due to its action, intracellular cAMP levels are increased. Basically, how the following processes will be found in this condition and its consequences for blood glucose: a) glycogenesis. b) glycogenolysis. c) glycolysis. d) gluconeogenesis.
