Study Notes
Mitochondria Overview
- Primary function is energy production through ATP synthesis, which is essential for cellular processes.
- Often referred to as the "powerhouse of the cell" due to their role in generating energy.
Mitochondrial Presence in Organisms
- Certain organisms, such as some protozoa and parasites, lack mitochondria in some of their cells, showcasing adaptations to different environments.
- The organism Giardia lamblia is known for completely losing its mitochondria during evolution.
Historical Discoveries
- Mitochondria were discovered by scientist Albert von Kölliker in the context of muscle cells, emphasizing their role in energy metabolism.
- The term "mitochondrion" was coined by Richard Altmann, highlighting its significance in cellular biology.
Physical Characteristics
- Mitochondria vary in size, typically ranging from 0.5 to 10 micrometers, allowing them to fit within different cell types and serve various functions.
