Euakryotic cells - Mitochondrion Flashcards
1
Q
What shape is the mitochondrion?
A
Sausage shaped organelle.
2
Q
What happens in the mitochondrion?
A
Where aerobic respiration takes place.
3
Q
What does the mitochondrion release?
A
Energy in the form of the molecules ATP from carbohydrates, lipids and other energy rich molecules.
4
Q
Cells that have many mitochondria…
A
Use a lot of energy.
eg muscle cells.
5
Q
What are mitochondria surrounded by?
A
A double membrane.
The outer membrane is simple and quite permeable.
The inner membrane is highly folded into cristae, which give a large surface area
6
Q
What is the space enclosed by the inner membrane called?
A
Mitochondrial matrix.
Contains small circular strands of DNA.
7
Q
What is the inner membrane studded with?
A
Stalked particles which are enzymes that make ATP.
