The ionic group coo- on succinate forms bonds with the succinate dehydrogenase
Dmitriy789 [7]

At neutral pH, the ionic group COO- on succinate makes bonds with the active site of succinate dehydrogenase. This bonding is required for succinate oxidation.

<h3>What is succinate oxidation?</h3>

In the Krebs cycle , succinate dehydrogenase catalyzes the oxidation of succinate to fumarate, with the resulting electrons being supplied to respiratory chain complex III to decrease oxygen and produce water.

SDH oxidizes succinate to fumarate during the citric acid cycle. SDH is structurally similar to fumarate reductase, an enzyme that catalyzes the opposite process during anaerobic respiration in bacteria.

Theoretically, how might researchers disrupt signal transduction pathways as possible treatments for cancer?
ivann1987 [24]

Answer:

d. disrupt the function of protein kinases involved in cell cycle regulation.

Explanation:

Protein kinases which are useful in cell cycles have major roles in the formation of tumors. So many of these protein kinases go through mutations. Cell cycles would be unable to be stoped and tumor would keep increasing.

A lot of receptors are G protein coupled. So it is going to be really helpful to alter and make G protein receptors to be inactive. Most if these kinases go through means of phosphorylation and dephosphorylation. Targeting these would cause disruption in signal transduction in cells with cancer
