Mitochondria Essay

The main function of the mitochondria is to convert fuel into a form of energy the cell can use. Specifically, the mitochondria is where pyruvate --derived from glucose-- is converted into ATP (Adenosine triphosphate) through cellular respiration. Cellular respiration involves four stages: glycolysis, the grooming phase, the citric acid cycle, and oxidative phosphorylation. The final two stages listed occur in the mitochondria.

First of all, the most important structure in the animal cell is the mitochondria. The mitochondria is the vital because it provides energy for the cell (Doc. 2). For example, without the mitochondria, organelles would function slowly because the cell has no energy (OI). In Document 3, it states “Breaking down the food and releasing’ energy” (Doc. 3). “The mitochondria are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell” (OI). According to Ms. Quitmeyer, the mitochondria is crucial to the animal cell, and

Mitochondria are small organelles found in eukaryotic cells which respire aerobically. They are responsible for generating energy from food to ‘power the cell’. They contain their own DNA, reproducing by dividing in 2. As they closely resemble bacteria, it gave the idea that they were derived from bacteria (which were engulfed by ancestors of the eukaryotes we know today). This idea has since been confirmed from further investigations, and it is now widely accepted. (Alberts et al., 2010a)

Mitochondria, dubbed the ‘powerhouse of the cell’, are a type of organelle present in most human cells. Their primary function is to generate Adenosine Triphosphate (ATP), the cell’s principal source of chemical energy. Unlike most other organelles, mitochondria store their own set of genetic material, distinct from the DNA situated in a cell’s nucleus. Although this ‘mitochondrial genome’ represents only 0.1% of a cell’s genetic information, it often plays a significant role in development.

Mitochondria are important because they allow our bodies to function by converting oxygen that we breathe in and the nutrients we ingest from food to energy we can use in the form of ATP (Adenosine triphosphate). This is done through aerobic respiration (requires oxygen), without the many mitochondria we have in our body we would not have sufficient energy from anaerobic respiration for our metabolic requirements. (Link its importance to its other functions- what would happen if it could not perform its functions e.g. lack of regulation of apoptosis and cancer- links to essays overall argument).

The mitochondria is known as the “power house” of a cell that functions at the site of respiration. Within the inner membrane, ATP synthesis occurs which provides energy to the cell and it other parts. Without function of a mitochondria, a cell would die; it has no energy to repair itself, has no energy to transport molecules across the membrane, transport nutrients, send signals to other cells, or any other processes. Metabolism, release of energy, movement, or forming new nucleotides would not occur simply because energy is not available.

Mitochondrion’s most important job is to produce energy through cellular respiration. Mitochondria does this by taking in nutrients from the cell itself, breaking it down and then turning it into energy. Then, the energy gathered is utilised by the cell to carry out various functions, hence this organelle is also known as the ‘powerhouse’ of the cell. Its purpose is to keep the cell full of energy.

What it is: Mitochondria are a part of eukaryotic cells and it takes in nutrients from the body and breaks it down and then it eventually turns it into energy.

The hub of energy metabolism, the mitochondrion, is found in virtually all eukaryotic cells, with the exception being erythrocytes. The mitochondrion generates cellular energy in the form of adenosine triphosphate (ATP), mostly by means of the oxidative phosphorylation (OXPHOS) system that is located in the inner mitochondrial membrane. The respiratory chain (CI-CIV) and ATP synthase (CV) is collectively known as the OXPHOS system, encoded by both nuclear DNA (nDNA) and mitochondrial DNA (mtDNA). The number of mitochondria per cell, ranging from hundreds to thousands, is controlled by the energy requirements of specific tissues with the greatest abundance of mitochondria found in metabolic active tissue (Pieczenik and Neustadt, 2007). Mitochondrial disease is caused when there is a defect in any of the numerous mitochondrial pathways, due to spontaneous or inherited mutations. Respiratory chain deficiencies (RCDs) are the largest subgroup of mitochondrial disease and occur when one of the four respiratory chain complexes become impaired. RCDs are considered to be one of the most common

Mitochondrial damage is a normal part of aging, but is accelerated in many metabolic disorders. Chronic deficiencies and gut imbalances can destroys the mitochondrial membranes and lead to the modern diseases we see today.

Mitochondria: a word many people have used in their vocabulary, but one that most people fail to understand. Why is the mitochondria famously known as the powerhouse of the cell? It is because of its energy production. The mitochondria is responsible for the large majority of the production of ATP(adenosine triphosphate for those who actually care). ATP is the molecule that provides energy for most of the body’s functions. This organelle also aids in the processes of cellular differentiation(the changing of one cell type to another) and cell death(literal programmed, predetermined death of a cell). The mitochondria is made up of several different regions that help the organelle to function properly. These regions include the outer membrane,

What are mitochondria? Mitochondria are the power plants for your cells. They convert the nutrients that you eat into energy. Logically then, the more mitochondria you have, the more fat you burn.

Mitochondria are organelles that are considered the “power generators” within the cell. Mitochondria convert oxygen and nutrients into adenosine triphosphate (ATP), which is the energy that the cell uses. The energy is produced from the breakdown of glucose. Along with creating energy for the cell, the mitochondria also help certain cells self-destruct after they have served their purpose or if they are damaged. In the article “In cleaning up misfolded proteins, cell powerhouses can break down" by Science Daily, researchers at John Hopkins discovered that mitochondria can dispose of unwanted protein clumps. Many of the protein clumps in their experiment broke down in the cell's mitochondria. The experiment revealed that too many misfolded

Mitochondrion is an importance structure that lies in the cytoplasm area. Mitochondrion is the plural word for mitochondria, which is the key organelle that converts energy from one form to another. Mitochondria changes the chemical energy stored in food into compounds that are more convenient for the cell to use. The mitochondrion contains two special membranes. The outer membrane surrounds the organelle, and the inner membrane has many folds that increase the surface area of the mitochondrion.

Mitochondria are double membrane organelles that are found in the cytosol in Eukaryotic cells. There are many within the cells, and their function is to produce ATP. The organelle originated from the endosymbiosis theory, which means the bacteria engulfed the cell and formed a mutualism relationship. Mitochondria can be used to measure age, health, and stress levels of individuals. Scientist use mitochondria as a measurement tool by using the reporter gene to produce a protein that when newly made appears green, and then when it ages, it appears red (UVA 2014). Furthermore, if mitochondria appear green they are producing a lot of ATP and functioning properly, if they appear red they are oxidized and are not performing correctly. (UVA 2014)
