(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
Substrate-level Phosphorylation vs Oxidative Phosphorylation from Chapter 12 / Lesson 5 235K Learn to differentiate substrate-level phosphorylation vs. oxidative phosphorylation. Know the importance of substrate-level phosphorylation for cellular energy. Understand the importance of substrate-level phosphoryla...
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?
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 ...
In which part of the citric acid cycle does substrate level phosphorylation occur? Explain what happens in the citric acid cycle and list four different products of the citric acid cycle. Give a brief explanation about the citric acid cycle. ...
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...
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 glutathione peroxidase to produce the oxidized form of glutathione, GSSG. The mineral selenium is an essential component of glutathi...
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 ...
7, top). Conversely, if mitochondria cease to provide ATP then the drop in ATP lowers the threshold at which the loss of substrate occurs. The worst case scenario is shown with AMP, which does not inhibit UCP (Fig. 7, bottom). Download: Download full-size image Fig. 7. Substrate ...
The formation of ATP from ADP is a phosphorylation reaction (a type of biological reaction) where we will see an addition of the phosphate group in the structure of the starting material. There are two types of phosphorylation for the formation ...
