Study Notes
Mitochondria Functions
- Mitochondria are not responsible for protein synthesis.
- The typical size of a mitochondrion is 0.5-1.5 μm in diameter.
- The lipid associated with Barth syndrome is cardiolipin.
- Uncoupling protein generates heat in brown adipose tissue by creating a proton leak across the inner mitochondrial membrane.
- Mitochondria are not involved in the process of transcription.
Mitochondria Characteristics
- The main function of mitochondria is to generate energy for the cell through cellular respiration.
- Cardiolipin is a phospholipid that plays a crucial role in maintaining the structure and function of mitochondrial membranes.
- Mitochondria can range in size from 0.5-1.5 μm in diameter, but their size can vary depending on the cell type and energy demands.
