mitochondrion Flashcards
1
Q
shape
A
rod- shaped
2
Q
size
A
1-10 um in length
3
Q
structures inside
A
- double membrane
- cristae
- matrix
4
Q
double membrane
A
controls entry and exit of material. the inner of the two membranes is folded to form extensions known as cristae
5
Q
cristae
A
extensions of the inner membrane. provide a large surface area for the attachment of enzymes and other proteins involved in respiration
6
Q
matrix
A
makes up remainder of the mitochondrion. it contains protein, lipids, ribosomes and dna that allows the mitochondria to control the production of some of their own proteins. many enzymes involved in respiration are found in the matrix
7
Q
function
A
- site of the aerobic stages of respiration
- responsible for the production of ATP from respiratory substances such as glucose. .^. there are lots of mitochondrion in cells that have a high level of metabolic activity so require high levels of ATP (eg muscle and epithelial cells)
