Rna polymerases carry out transcription at much lower rates than dna polymerases carry out replication. Why is greater efficiency more important in replication than in transcription?

DNA polymerase is responsible for the catalysis of the replication of a vast region of DNA and the efficiency/speed of the replication is necessary to complete the replication process swiftly.

Explanation:

The difference between replication and transcription, is that in the replication process the DNA is making more copies of itself and in transcription, the DNA is being copied into RNA. DNA replication occurs in preparation for cell division, and transcription occurs in preparation for protein translation

This depends on the speed and duration of enzymatic activities of the  two enzymes.

DNA polymerises need to replicate  the entire long length of  DNA strands, thus enough time commitment and energy is needed for this.Therefore greater efficiency should be available to undertake this.

However,RNA polymerase do not need to transcribed the entire length of the chromosomes, only the essential small regions ( exons) of the  DNA  need to be transcribed. Thus  lesser speed and time is committed with  low energy. and efficiency.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
