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 and chloroplasts have two membranes that surround them. The inner membrane is probably from the engulfed bacterium and this is supported by that the enzymes and proteins are most like their counterparts in prokaryotes. The outer membrane is formed from the plasma membrane or endoplasmic reticulum of the host cell. The electron transport enzymes and the H+ ATPase are only found in the mitochondria and chloroplasts of the eukaryotic cell. (2)

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.

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)

How is the mitochondria structure? It’s made of two membranes: first, the outer membrane, the mitochondria is covered by it, it’s like it was the skin; then we can find the inner membrane, it folds over the mitochondria many times and creates cristae (layered structures). The mitochondria

Each mitochondrion has a double-layered membrane like the cell membrane, however the inner layer is folder which produces ‘shelves’ which are known as cristae, this is where the end stages of glucose oxidation are located. The energy that has been released is stored until required by a ‘chemical battery’ called adenosine triphosphate.

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: The mitochondria makes energy for the cell. The mitochondria is inside the yarn making energy for the ball to move and change speeds.

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).

Vacuole: Helps with intracellular digestion and throws out the waste products in the cell. The plant vacuole is bigger than the vacuole in a animal cell. The plant vacuole plays many jobs, such as storing nutrients and waste products, helps the cell grow bigger, and controls turgor pressure in the

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.

The molecule is an important part of the inner part of the mitochondria in which the actual production of the energy occurs.

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.

Organelles are the internal structures of the cell that are important for the cell to survive. Each organelle has a specific function for the cell. The types of organelles in the cell can be different from each other depending on the type of cell. Plant cells and animal cells both have a cytoskeleton, endoplasmic reticulum (smooth and rough), golgi apparatus, mitochondrion, nucleus, plasma membrane, and ribosomes. Animal and plant cells also have vacuoles, but they are rarely found in animal cells. Vacuoles in animal cells are very small compared to the vacuoles in plant cells. Lysosomes are also rarely found in plant cells but mostly found in animal cells.
