Mitochondria have more than one membrane.
C
The folds of the inner mitochondrial membrane are called cristae.

E
Mitochondria contain ribosomes in the intermembrane space.
Verified step by step guidance1
Understand the structure and function of mitochondria: Mitochondria are known as the powerhouse of the cell, involved in energy metabolism through the process of oxidative phosphorylation.
Recognize that mitochondria have a double membrane structure: They consist of an outer membrane and a highly folded inner membrane, which increases the surface area for energy production.
Identify the term 'cristae': The folds of the inner mitochondrial membrane are called cristae, which play a crucial role in the electron transport chain and ATP synthesis.
Acknowledge that mitochondria have their own genetic material: Mitochondria possess their own circular DNA, which is separate from the nuclear DNA, allowing them to produce some of their own proteins.
Clarify the location of ribosomes in mitochondria: Ribosomes are found in the mitochondrial matrix, not in the intermembrane space. The statement that mitochondria contain ribosomes in the intermembrane space is false.
