15 Questions
What is the primary function of the inner membrane of the mitochondria?
To increase the surface area for enzyme attachment
What is the purpose of the intermembrane space between the inner and outer membranes of the mitochondria?
To contain cytochrome c and other proteins involved in the electron transport chain
How do the cristae in the inner membrane of the mitochondria contribute to the organelle's function?
They increase the surface area for enzyme attachment, improving the efficiency of cellular respiration
What is the primary role of the outer membrane of the mitochondria?
To allow the passage of small molecules in and out of the mitochondria
What is the main difference between the inner and outer membranes of the mitochondria?
The outer membrane is smooth, while the inner membrane is folded into cristae
What is the primary function of the mitochondrial matrix?
To contain the enzymes for the Krebs cycle and fatty acid oxidation
How do the cristae in the inner membrane of the mitochondria vary in shape and arrangement?
They can be densely or sparsely packed, and their shape varies depending on the cell type
What is the primary role of the transport proteins found in the inner membrane of the mitochondria?
To facilitate the movement of small molecules in and out of the matrix
Which of the following statements about mitochondria is true?
Mitochondria are responsible for cellular respiration and energy production.
What is the typical size range of mitochondria?
0.5 - 1.0 micrometers
How can mitochondria change their shape?
Mitochondria can change their shape from spherical to oval or rod-shaped.
Where are mitochondria typically located within a cell?
In the cytoplasm
Which of the following cell types is likely to have a higher number of mitochondria?
Muscle cells
What is the purpose of the fatty droplets located near mitochondria in muscle cells?
To provide energy for cellular respiration
How do mitochondria reproduce?
They divide themselves in the middle to produce two daughter mitochondria.
Learn about the crucial role of mitochondria in cellular respiration and energy production in living organisms. Explore how this organelle functions as the powerhouse of the cell, providing essential energy for normal cell functioning and survival.
