What are the products of Anaerobic Respiration in yeast?
8090 [49]

The products of anaerobic respiration in yeast are carbon dioxide and ethanol.

<h3>Anaerobic respiration</h3>

This refers to respiration in the absence of oxygen.

In the absence of oxygen, both the citric acid cycle and the electron transport chain cannot proceed. Thus, only glycolysis takes place.

The two pyruvate molecules produced in anaerobic respiration in yeast are converted to ethanol, instead.

aleksley [76]

Ribonucleic acid (rna) and additional deoxyribonucleic acid (dna) surrounds genes. in a process called methylation, they enhance, silence, or alter genetic instructions.

<h3>What is DNA methylation?</h3>
  • Adding methyl groups to the DNA molecule is a biological process known as DNA methylation. Methylation has the ability to change a DNA region's activity without changing the sequence.
  • When DNA methylation takes place at a gene promoter, it frequently decreases gene transcription.
  • DNA methylation plays an important role in a number of critical processes in mammals, including aging, cancer, X-chromosome inactivation, genomic imprinting, and transposable element repression.
  • The majority of eukaryotic genomes contain DNA methylation, a dynamic epigenetic alteration. It is well recognized to cause a high rate of CpG to TpG mutations.
  • However, nothing is known about the connection between the rate of germline mutation and the dynamics of methylation during germline development.
