The Mitochondri An Essential Organelle That Produces Energy For The Cell

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.

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 – Spherical bodies in the cytoplasm where energy is produced. The cell uses this energy to perform the specific work necessary for cell survival and function.

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

The mitochondria is an organelle of a cell. It works as it was the digestive system, it’s in charge of obtaining the nutrients, then break them down, and finally, all that work is for maintaining the cell full of energy, so they would be as the power plants of the cell. The mitochondria are in charge of creating 90% of the energy that our bodies need so it can sustain life and support our growth. The mitochondria are small organelles that floats all through the cell. Some cells have many, lots of mitochondria, but others just have none; for example, the muscle cells need a lot of energy, so they contain lots of mitochondria, otherwise, neurons don’t need as much. Depending of the quantity of energy that the cell needs, mitochondria could be created.

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 provide the energy used within our cell to carry the vast variety of actives that is fundamental life (). Without the huge input of ATP derived from the mitochondria, the

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.

Mitochondria convert the chemical energy stored in food into compounds that are more convenient for the cell to use. They are the power plants of the cell.

3. Mitochondria and chloroplasts are both circular or ovoid in shape, surrounded by double phosopholipid bilayers, have an intermembrane, and both are involved in ATP production by way of proton gradient. Also, both have ATP-synthases and electron transport chains appearing on the thylakoid membrane of the chloroplast and on the cristae of mitochondria.

Mitochondria are the powerhouse of the cell. They are organelles that convert the chemical energy stored in food into compounds that are more convenient for the cell to use. They are organelles that act like an digestive system which takes in nutrients. Mitochondria are small organelles floating free throughout the cell. It is found in the eukaryotic cell. Mitochondria contain their own genetic material. Mitochondria comes from the greek language.

Previously mitochondria were considered to be static and isolated organelles. However, it has now been established that mitochondria form a complex, interconnected, and highly dynamic network. Mitochondria dynamics also involves changes in mitochondrial morphology, number in the cell and movement along the cytoskeleton. Mitochondrial dynamics is said to be tightly regulated by mitochondrial fusion and fission.

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.

Chloroplasts are enclosed in a double membrane that creates a compartment between the membranes called stroma. The primary purpose of the mitochondria is to conduct cellular respiration, converting the chemical energy of food molecules into high-energy compounds. Similar to chloroplasts, the mitochondria is enclosed by a double membrane that creates a fluid-filled intermembrane space. Proteins are a second type of intracellular organic molecule. These substances are made from chains of smaller molecules called amino acids.

Introduction: - The mitochondria is a double membrane organelle that is found in all eukaryotic organisms. There is some evidence that proves some eukaryotes lack mitochondria, but there is no true evidence about complete lack of mitochondria in the organisms. Mitochondria is known as a power house of the living body cell. They store energy in the cell and release it as needed. Every structure in Mitochondria have their own specific roles which helps in storing energy (See Figure 1 for details). Evidence shows that mitochondria evolved from primitive bacteria. Is it really evolved from primary bacteria or were they the new adaptation in the plant and animal body? In this paper we are going to see how Mitochondrion have been evolved in different species and what methods have been used to prove that evolution. There is still debate between scientists about whether mitochondrion really evolved from bacteria or if it was present in the cells before bacteria were present. Yung et al. [1] says that Mitochondria’s cytochromes c (which is a mitochondrial intermembrane protein that is loosely attached to the inner membrane of mitochondrial membrane) is relatively close to the bacterial medium subunit in sequence of cytochrome. However,
