13 Questions
What is the function of cristae in the mitochondria?
Increase the surface area of the membrane for chemical reactions
Where is mitochondrial DNA (mtDNA) located, and how does it differ from nuclear DNA?
Located in the matrix of the inner membrane; mtDNA is more similar to bacterial DNA and contains fewer base pairs
Explain the significance of the maternal inheritance of mtDNA in tracing genetic lines.
Maternal inheritance of mtDNA allows for tracing genetic lines and determining common ancestry.
Mitochondria are also involved in other tasks apart from energy production.
True
Mitochondria are typically visible under the microscope without staining.
False
Mitochondria have two membranes, an inner one and an outer one.
True
The outer membrane of mitochondria allows large molecules to pass freely through it.
False
The inner membrane of mitochondria is impermeable to most molecules due to the presence of porins.
False
Mitochondria are only responsible for energy production and do not perform any other important tasks.
False
The DNA in mitochondria is more similar to plant DNA than bacterial DNA.
False
The child always inherits their mtDNA from their father.
False
Mitochondria are constantly dividing and bonding together, forming ever-changing networks.
True
Mature red blood cells have a greater number of mitochondria compared to liver cells.
False
Test your knowledge about the functions and importance of mitochondria in human cells. Explore their role in energy production, cell signaling, and apoptosis.
