1
Q
Function of lysosomes
A
- transports RER to golgi
2
Q
Outline the role of acid hydrolases in lysosomes
A
- digests pathogens
- digests worn out organelles
- catalyses hydrolysis
3
Q
Suggest how carrier proteins maintain the lower pH within lysosomes
A
- pumps hydrogen ions into the lysosome
- against concentration gradient by active transport using ATP
4
Q
Features to confirm that the cell is prokaryotic and not eukaryotic
A
- circular dna
- naked dna
- peptidoglycan cell wall
5
Q
Difference between prokaryotic and eukaryotic cell
A
Peptidogylan cell wall- cellulose cell wall
Circular dna- linear dna
No true nucleus- true nucleus
70s ribosomes only- 70s and 80s ribosomes
