Telomerase is an enzyme that is responsible for the addition of telomeric units or repeats to the end of the bacterial chromosome. This enzyme is critical for maintaining the length of the telomere. Mammalian somatic cells lack the activity of this enzyme and therefore, results in the shortening of telomeres in each of the cellular respiration processes.

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

Telomerase is an enzyme that is responsible for the addition of telomeric units or repeats to the end of the bacterial chromosome. This enzyme is critical for maintaining the length of the telomere. Mammalian somatic cells lack the activity of this enzyme and therefore, results in the shortening of telomeres in each of the cellular respiration processes.

Expert Solution & Answer

Explanation of Solution

A phenomenon in which the normal diploid cells end the division process is known as cellular senescence. The somatic cells present in the human as well as the majority of animal exhibit the feature of senescence. Such cells undergo division for a particular number of generations and then cease their activity.

A portion of the telomeres (cap ends of the chromosome) is lost during every division until the complete telomeric region disappears as well as the essential genes are lost. On the other hand, the yeast Saccharomyces cerevisiae is a single-celled microbe that continues to grow as well as it divides throughout its life cycle. Therefore, senescence might be the possible reason for the cessation of telomerase activity in somatic cells.
