    NameOxidation of the body
    phosphatization
    is mainly affected by the cell's regulation of energy needs(i) ATP/ADP value on the direct impact of oxidation phosphate in the membrane has adenosine transposase, catalytic mitochondrial ATP and mitochondrial ADP exchange, ATP molecules dissophase with 4 negative charges, and ADP molecules dissofides with 3 negative charges, because the mitochondrial membrane inside and outside the trans-membrane ψ), the outer side of the inner membrane is positively charged, the inner membrane is negatively charged, so the ATP line-out granules are faster than the entering mitochondrial speed, and the ADP-in mitochondrial speed is faster than the out-line granules. Pi into mitochondrials is also catalyzed by phosphate transtosase, phosphate transdesase catalytic OH and Pi exchange, phosphate transtosase catalytic Pi2- and phosphate transdesinate (such as apple acid) exchange.When there is sufficient oxygen and substrate supply in the mitochondrials, phosphate oxide will continue until ADP-Pi is fully synthesized at ATP, at which point breathing is reduced to a minimum speed, and if ADP is added, oxygen consumption will suddenly increase, indicating that ADP controls the rate of oxidation phosphate, which is known as respiratory control.the energy consumption of the body increases, ATP decomposition produces ADP, ATP out-of-line mitochondrials increase, ADP enter mitochondrials increase, mitochondrial ATP/ADP value decreases, so that phosphate oxide speed is accelerated, ADP-Pi receives energy to generate ATP. When the body consumes less energy, the ATP/ADP value increases in the mitochondrial body, and the ADP concentration in the mitochondrial decreases, which slows down the rate of phosphate oxide.(ii) When the ATP/ADP value is increased, the phosphorylation rate is slowed down, resulting in slower NADH oxidation and higher NADH concentration, which inhibits the oxidation and TCA cyclic activity of acetone
    dhydrogenase
    system, isocitric acid dehydrogenase, α-ketone dihydrogenase and citric acid synthesis enzyme.(iii) THE direct impact of ATP/ADP values on key enzymes ATP/ADP value increase will inhibit many key enzymes in the body, such as variant inhibition of fructose phosphate
    kinase
    , acetone kinase and isocitric acid dehydrogenase, but also inhibit acetone dehydrase, α-ketone dihydrogenase system, through direct feedback to inhibit the decomposition of sugar and TCA cycle.
