Mitochondrion

Mitochondrion is an organelle that exists within the cytoplasm of eukaryote cells, they are considered to be one of the most important organelles. Mitochondrion is usually oval in shape and can vary in size from 0.5 - 1µm. Mitochondrion is composed of a double membrane, the outer membrane is smooth and encompasses the organelle whereas the inner membrane is folded to form layered structures called cristae. In between the outer and inner membrane, is an area called the Intermembrane space. Inside the inner membrane consists a gel like fluid called the matrix, here enzymes that are involved in aerobic respiration can be found. Mitochondrion also contains its own DNA and ribosomes, separate from the eukaryote cell it resides in, these are also located in the matrix.…

Mitochondrion are made of two membranes. The outer membrane covers the organelle and acts as a layer of skin, whereas the inner membrane constantly folds over and creates layered structures called Cristae (The constant folding increases the surface area of the organelle). And the fluid inside the organelle is called the matrix. The matrix carry the specific DNA and ribosomes for the mitochondria, because the organelle carries its own DNA. Site of aerobic respiration and provides energy (ATP) to…

The mitochondrion of the cell is the powerhouse of the cell meaning it is responsible for providing energy and respiration. The mitochondrion is used to provide the necessary energy which is generated for the cells to do its job. We can take brain cells for example, which need a lot of energy to be able to communicate with other body parts. This is achieved by substances being transported around the body along with the cells so they can be reached by those body parts which are far away. Tiny…

energy (See Figure 1 for details). Evidence shows that the mitochondria evolved from primitive bacteria’s. Is it really evolved from the primitive bacteria or are there any other evidences that mitochondrion has been evolved from. Here, in…

The mitochondria take over this category of course. It is a on a constant prowl to provide energy for a cell. The mitochondrion is very unique of course. It has said to have been evolved from bacteria, by a process called endosynbiosis. It has an outer and inner membrane structure. The mitochondrion has an “oblong” oval type shape found in both animal and plant cells. Some cells don’t contain a true mitochondria in which are replaced by hemoglobin cells, like the red blood cells. The…

The mitochondrion is an organelle which produces ATP or energy for all cells. The ATP produced by the mitochondria can be used to measure certain physical activities of fruit flies. In this experiment the development, climbing, flight, and in vitro activity of Drosophilia Melanogaster flies were tested. Three different strands of flies were used. One strand was the wild-type (wt) fly, which had normal mitochondria without any mutations. Another stand was the W501 strain (hybrid) which had…

Oxaloacetate, found in the mitochondrion, is a four-carbon molecule. In this project we performed a Bradford Assay and an SDH (Succinate Dehydrogenase) Assay. The goal of this project was to work with enzymes to gain a better understanding of how enzymes function and how they are impacted with the introduction of a variety of factors. A significant part of the experiment was determining the protein concentration of the prepared mitochondrial fraction which will be further explained. The reason…

include poor growth, loss of muscle coordination, learning disabilities and heart disease," Peter Sutovsky said, a professor of reproductive physiology at Mizzou who conducted research on Mitochondrial irregularities with his partner, Won-Hee song, at Proceedings of the National Academy of Sciences (PNAS). These diseases are usually caused by heteroplasmy, or an incorrect inheritance of mtDNA (Mitochondrial DNA). To understand heteroplasmy, first one must know that when DNA is inherited from…

organisms, respiration occurs to maximize ATP production; this is contrary to anaerobic respiration, which occurs during the absence of a ready supply of oxygen (mostly in prokaryotic organisms). Plants are autotrophs, meaning that the provided their own food. This is unlike animals, who need to digest other organisms for energy. Because of the autotrophic nature of plants, they perform photosynthesis and cellular respiration simultaneously. Glycolysis proceed cellular respiration, and it is…

The outer membrane shields the organelle and represses it like a skin (3). It also allows the passage of smaller molecules that contain mitochondrion sequences. The inner membrane folds over many times and produces layered structures called cristae (4). The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur (4). If you have more…
