Answer:

Telomerase

Explanation:

Repetitive regions at the ends of Chromosomes are known as telomeres and these are crucial for chromosomal stability. There is no gene present and they provide protection to internal parts of chromosome. The telomeres are eaten up slowly by ‘DNA REPAIR MECHANISM’ after many division cycles, which is considered as ageing. That why, a cell can divide only certain number of times.

Some cells have ability to express an enzyme telomerase that maintain the length of telomere. The telomerase enzyme contributes to cell immortality by rebuilding the damaged telomere. Thus telomerase enzyme is necessary for cancer initiation and survival of tumor. Telomerase enzyme can make its own DNA by using its RNA as template . It extends the overhang strands of DNA by using a comlementary DNA.

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.
