For what purpose is mitochondrial genomics used

2 answers:

8 0

The mitochondrial genome is particularly used in the genetics of human populations, or in agronomy, as a genetic marker for evolutionary biology.

The mitochondrial genome encodes the proteins involved in oxidative phosphorylation, as well as its rRNAs and tRNAs.

During evolution, the mitochondria has conserved their own genome. It is essential for the proper functioning of these organelles, which is the production of cellular energy.

The mitochondria are famously known as the powerhouse of the cell since it is the one that gives the cells energy that is also used by the human being. This energy conversion is called oxidative phosphorylation. Mitochondria are found in eukaryotic cells, including humans. These organelles also had its own genome, or what we called as DNA which is known as mitochondrial DNA, or mtDNA which is present in the mitochondrial matrix. The role of mtDNA or mitochondrial DNA is to convert the energy from food into any other forms that it thinks the cell can use. It is containing 37 genes which are all necessary for a normal mitochondrial function.

Which describes the process of fermentation?

pav-90 [236]

Explanation:

anaerobic process that restores NAD+ supply

Within cells, aerobic respiration may not occur due to several factors:

- a lack of inorganic, final electron acceptors
-incomplete or lack of a complete electron transport system
-missing genes for enzymes within the Kreb's cycle

Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+ an oxidized form of NADH, the main electron carrier in glycolysis. Pyruvate is produced in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation.

Further Explanation:

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Which occurs during translation

RideAnS [48]

Answer:

Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. ... Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination. During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.

In "simple columnar epithelium," which word describes cell shape and which word describes the number of cell layers?

dolphi86 [110]

Answer:columnar describes cell shape.

Simple describe the number of layers

Explanation: epithelial tissues are one of the four major tissues of the body.the others being nervous, muscular, connective tissues.

Epithelial tissues are made up of thin cells that cover the external and internal surface of the body.

The cells may form one layer or more and they occur in several shapes.if they form one layer ,it is called simple.if they form several layers,it is called stratified.

Some are called pseudo-stratified because the cells occur with varying lengths and give the impression of stratified but they are actually made up of one layer.

Simple columnar epithelium is a single layer of tall, closely packed cells. They possess cellular extensions ,such as microvilli in the small intestine, or the cilia in the female reproductive tract.
