What is the cytoskeleton?
The network of protein fibres and microtubles found within the cell that gives structure to the cell and is responsible for the movement of many materials within it.
35 of 52
What are the two types of protein fibre that make up the cytoskeleton?
Actin and Tubulin.
36 of 52
What are actin?
Fibres like the protein fibres found in muscle cells.
37 of 52
What are the roles of actin?
1-White blood cell movement.2-Organelle movement.
38 of 52
What are tubulin?
These Protein fibres form cylinders called microtubules.
39 of 52
What are the roles of tubulin?
1-Movement of a call through liquid.2-Waft a liquid past the cell.3-Organelle/chromosome movement.
40 of 52
The cytoskeleton protein fibres require energy to power motors to produce movement,where does this energy come from?
1-Aerobic respiration in the mitochondria.2-ATP is produces which releases the energy.
41 of 52
What are the roles of the cytoskeleton?
1-Provides strength/support to cell.2-Determines shape for endo/exocytosis.3-Movement of organelles/RNA/protein/chromosomes.4-Movement of flagella for cell movement.5-Movement of cilia to move mucus.6-hold organelles in place.7-make up spindle fibres

1-Contains essential genetic information that can be transmitted to next generation.2-Controls activities of cell.
46 of 52
What is the function of the plasmid?
1-Contains beneficial genetic information e.g. Antibiotic resistance.2-Can be copied and passed on to other bacterial cells.
47 of 52
What is the function of mesosome?
1-Aerobic respiration.2-Production of ATP. 3-Releases energy.
48 of 52
What is the function of the slime layer/capsule?
1-Protection from dehydration.2-Contains hydrolytic enzymes for protection from engulfment from White blood cells.
49 of 52
What is division of labour?
Any system where different parts perform specialised functions, each contributing to the functioning of the whole.
50 of 52
What are the first 3 stages of division of labour in protein synthesis?
1)mRNA leaves nucleus via nuclear pore.2)mRNA travels through RER and to ribosomes,which read genetic code and make proteins.3)Transport vesicles transport proteins from RER to golgi apparatus.
51 of 52
What are the next 3 stages of division of labour in protein synthesis?
4)Golf apparatus modifies and packages proteins to secretory vesicles.5)Secretory vesicles transport proteins from golgi body to plasma membrane.6)Vesicles fuse with plasma membrane, this is called exocytosis and secretes the proteins.
