What is the Difference Between Cristae and Cisternae?
🆚 Go to Comparative Table 🆚Cristae and cisternae are structures found in different cellular organelles, with distinct functions and structures:
Cristae:
- Found in mitochondria.
- Foldings of the inner mitochondrial membrane.
- Provide a large surface area for the electron transport chain and ATP production.
- Contain proteins such as ATP synthase and cytochromes.
Cisternae:
- Found in the Golgi apparatus and the endoplasmic reticulum.
- Flattened membrane-bound compartments.
- Play a role in modifying and sorting proteins.
- Contain different enzymes involved in the phosphorylation and glycosylation of proteins.
In summary, cristae and cisternae are distinct structures in the mitochondria and endoplasmic reticulum/Golgi apparatus, respectively. Cristae increase the surface area of the inner mitochondrial membrane to enhance ATP production, while cisternae are involved in modifying and sorting proteins.
Comparative Table: Cristae vs Cisternae
Cristae and cisternae are two distinct structures found in different cellular organelles. Here is a table comparing their characteristics:
Feature | Cristae | Cisternae |
---|---|---|
Location | Mitochondria | Golgi apparatus and endoplasmic reticulum |
Structure | Folds of the inner mitochondrial membrane | Flattened, disk-like structures |
Function | Expand the surface area of the inner mitochondrial membrane to increase ATP production | Involved in the modification of proteins into their final products |
Enzymes | Contain ATP synthases and cytochromes | Contain different types of enzymes |
Cristae are the folds of the inner mitochondrial membrane, which help expand the surface area to increase ATP production. On the other hand, cisternae are the flattened, disk-like structures found in the Golgi apparatus and endoplasmic reticulum, and they are involved in the modification of proteins into their final products.
