The mitochondria is the location inside the cell where the energy, called adenosine triphosphate, or ATP, is made. This specific part of the cell is composed of rod-shaped organelles. Mitochondria are the animal-version chloroplast, where the energy cycle in plants takes place.
In a normal animal or human cell, there can be anywhere between a thousand and two thousand mitochondria. The energy created by organelle is done through the process of cellular respiration. Every living cell in an organism contains this structure because every living cell plays a role in respiration. Even though these structures are important in the cells, they only range in size between a half and one micrometer. Along with being the main area of energy production, the mitochondria play a part in a number of other functions including cell signaling, growth and cell cycles. The structure has both an inner and outer membrane, which contain a large number of very important proteins. The outer membrane contains proteins called porins, which form channels and let material diffuse from one side of the membrane structure to another. The inner membrane contains around a fifth of the total protein in the mitochondrion structure. The inner membrane does not have porins, which helps makes it impenetrable to other molecules. Along with this, the inner membrane has a phospholipid called cardiolipin which adds another layer of protection to make it even harder for anything to enter the structure that should not be there.Learn More
Cellular respiration is used to make ATP, adenosine triphosphate, which provides the energy that the cells need to be able to carry out their functions in living cells. All cells carry out some form of cellular respiration, either aerobic or anaerobic. The cells that perform aerobic respiration need oxygen to carry out the process, while cells that use the anaerobic process do not, instead relying on fermentation.Full Answer >
The energy-converting organelle found in plant and algae cells is called the chloroplast. Only some plants and algae have chloroplasts.Full Answer >
The largest organelle in plant cells containing the cell sap is the vacuole. Plant cells usually have a single vacuole that can take up 80 percent or more of the volume of a cell.Full Answer >
Carl Rod Nave of Georgia State University explains that biologists consider ATP, short for adenosine triphosphate, to be the energy currency of life. An ATP molecule stores energy that organisms require to perform vital functions and processes. During cellular respiration, ADP converts into ATP storage molecules which supply energy.Full Answer >
