(What's the substrate-level phosphorylation and gave two examples) 相关知识点: 试题来源: 解析 底物水平磷酸化是代谢过程中,底物分子直接将高能磷酸基团转移给ADP生成ATP的过程。两个例子:糖酵解中的1,3-二磷酸甘油酸生成ATP;柠檬酸循环中琥珀酰-CoA生成ATP。 底物水平磷酸化发生在酶
What is substrate-level phosphorylation?Phosphorylation:The term phosphorylation refers to the addition of a phosphate group to a particular molecule, protein, enzyme, etc. Phosphorylation can occur by the action of enzymes called kinases or through other means....
as well. Low blood glucose level, also known as low blood sugar, results in the production of glucagon. This hormone is produced in the pancreas and raises blood sugar. It inhibits the activity of pyruvate kinase in the final glycolysis step, preventing substrate phosphorylation from taking ...
What is substrate-level ATP formation?"Nuclear" Power:The A in ATP stands for Adenosine, an Adenine base bound to a ribose sugar, just like a nucleotide in RNA. The difference is that ribose is bound on the other to not one but three phosphate groups in tandem (hence tri-phosphate or ...
what mechanism do metabolism energy of you comes from? Answer :The metabolism energy is ATP ,it comes from two ways ,substrate-level phosphorylation and oxidative phosphorylation . 1.6, if glucose and fatty acid have equal numbers of carbons, which one would have the most energy, why?
and bifidum pathway. The bacteria that use the homofermentative pathway convert glucose into two molecules of lactate and use this reaction to carry out substrate-level phosphorylation in order to make two molecules of ATP. Examples of homofermentative bacteria includeStreptococcus,Lactococcus...
What process requires oxygen to function? a. Aerobic respiration b. Anaerobic respiration c. Lactic fermentation d. Alcoholic fermentation e. Substrate-level phosphorylation In which organelle of the cell does the anaerobic type of respiration occur?
where DG°ATP is the free energy of ATP hydrolysis under standard conditions of temperature, pressure, and substrate/product concentrations in solution, R is the gas constant, and T is the temperature in °K[14]. An important aspect of this is that the amount of available energy does not ...

Beta-carotene, the major carotenoid precursor of vitamin A, is the most efficient “quencher” of singlet oxygen (40). Glutathione serves as a substrate for glutathione peroxidase, an enzyme that functions to remove hydrogen peroxide. The reduced form of glutathione (GSH) is acted on by ...
