Parts of a cell where aerobic production (also known as cell respiration) takes place.
Specialized subcellular compartment in the muscle cell. The powerhouse of the cell, capable of producing mass quantities of ATP to fuel muscular contractions.
Spherical or rod-shaped organelles, found outside the nucleus, that produce energy for cells through cellular respiration.
Granular or rod-shaped bodies in a cell that contain the zyme systems required in the citric acid cycle, electron transport, and oxidative phosphorylation.
Important compartment of eukaryotic cells; site of the Krebs cycle and respiration chain (production of ATP); mitochondria have their own DNA, replication, transcription and ribosomes.
The largest organelles in the cytoplasm. The cell contain important enzymatic, oxidative, and respiratory systems.
Organelle in the cell; contains the citric acid cycle and respiration coupled with ATP synthesis; involved in fatty acid oxidation. Cells vary in the number of mitochondria they contain. Liver cells contain 800-1200; ova contain up to 20,000.
Mitochondria are organelles within cells that possess the capability of producing energy from macronutrients. During exercise training, mitochondria proliferate and their function is enhanced, allowing for more energy production than during the untrained state.
Small, spherical or rod-shaped components found in the cytoplasm of cells, the fluid in which most chemical changes take place. Mitochondria are the principal sites at which cells oxidize food, thereby generating energy in the form of ATP (adenosine triphosphate). Mitochondria contain enzymes used in the synthesis of proteins. They also contain RNA and DNA, which they can use to replicate and code their metabolic activities. On average, each cell contains between 500 and 2,000 mitochondria.
The rod-like bodies in the cells of the body which contain the enzymes necessary for the activity of the cell. They have been described as the power plant of the cell.
The cellular organelles responsible for generating energy through the process of respiration.
Tiny organelles located within cells where cellular respiration takes place. The mitochondria possess a double membrane structure. The inner membrane is extensively folded, offering ample surface area for respiration processes. Cells with high energy demands, like muscle cells, house numerous mitochondria.
