Cristae are the folds of the inner membrane of mitochondria. They increase the surface area for biochemical reactions, such as cellular respiration, to occur more efficiently.
congrats on reading the definition of cristae. now let's actually learn it.
Cristae are essential for ATP production because they house the proteins involved in the electron transport chain.
The increased surface area provided by cristae allows for a greater number of ATP synthase enzymes to be present.
Cristae play a crucial role in energy metabolism within eukaryotic cells.
The structure of cristae can vary between different types of cells depending on their metabolic activity.
Cristae are dynamic structures that can change shape and size depending on the cell's energy demands.
