Mitochondria and chloroplasts are organelles of energy conversion that carry their own DNA

Mitochondria – release energy from nutrients and convert it to ATP
Chloroplasts – capture solar energy and store it in carbohydrates

Organelles in a cell

Mitochondria
Mitochondria are membrane-enclosed organelles distributed through the cytosol of most eukaryotic cells.
Their main function is the conversion of the potential energy of food molecules into ATP.
Every type of cell has a different amount of mitochondria.
There are more mitochondria in cells that have to perform lots of work, for example - your leg muscle cells, heart muscle cells etc.
Other cells need less energy to do their work and have less mitochondria.

Mitochondrion

Size: 0.5 x 1.0 µm
Copy number per cell: ~2000

Particles: portion of integral membrane proteins The mitochondrion

Cristae are sometimes tubular and are connected to the inner membrane space through small holes that restrict the flow of protons. This restriction causes an increase in the pH gradient and increases the ATP production.

    Mitochondria carry out critical steps in the extraction of energy from food, and the conversion of that “trapped” energy to a useful form. They are the cell’s “power plants.” Chloroplasts are organelles found in algae and in the green parts of plants. Chloroplasts have two membranes surrounding them, as well as an internal system of stacked membrane discs.…

    Mitochondria- Mitochondria are the energy factories of the cells. The energy currency for the work that animals must do is the energy-rich molecule adenosine triphosphate (ATP). The ATP is produced in the mitochondria using energy stored in food. Just as the chloroplasts in plants act as sugar factories for the supply of ordered molecules to the plant, the mitochondria in animals and plants act to produce the ordered ATP molecules as the energy supply for the processes of life.…

    Respiration is a very important process for every living organism. While it is typically thought of as breathing in oxygen, and exhaling carbon dioxide, like all things, it must take place at the cellular level. The electron transport chain is responsible for cellular respiration. The process uses four complexes; the fourth is cytochrome c oxidase. Cytochrome C oxidase is responsible for the reduction of oxygen to water. There are thirteen subunits that make up the complete complex. Each of these is coded by its own gene in the DNA. Most of them are in the nuclear DNA; however three are encoded by mitochondrial DNA, including COX1 (Karp, 2010) (Li, Youfen et al.).…

    In the article Beware of Data is went over the Uniform Crime Report and it explained it included four types of Violent crimes, these crimes were murder/nonnegligent manslaughter, forcible rape, robbery and aggravated assault, and three types of property crime such as burglary, larceny-theft and motor vehicle theft. The Uniform crime report does include arson but that is on a very limited basis. This data base is very impressive with how it collect and records these crimes but at the same time like any data base it does have its flaws. These flaws are that the actual crime levels are not accurate due to not all of the crimes committed are called into police agencies to have reports filed, some of these crimes can be Rape and assaults since victims could know the suspect and they fear retribution from the suspect. To redress the weaknesses in the reports the Bureau of Justice created another data base called the National Crime Victimization Survey. This data base surveys individuals as well as households around the country asking if they have been victims of crimes over the last 6 months and if they had it collects information on what happened. This data base shows that the crime rates are a lot higher than the Uniform Crime report especially for violent crimes. This was a brief summary of what this article was going over.…
