Phagocytosis and exocytosis ( 1 week off)

Question 1

What happens in the phagocytosis process?

Answer 1

1. Action makes little smalls called pseupods which engulf the bacteria
2. The bacteria moves in the pseudpods area and tne ends of the pseudopods infuse
3. The actin molecules at the end of the pseudopods pull the vesicle in the cell that contain the bacteria
4. It becomes a phagosome will allows proton pumps so proton enter the vesicle but it goes aganist its concentration gradient so ATP is required , once it is in it make the vesicle negative
5. The phagosomes bind with the lysosomes,(Phagolysosmes) the lysosomes break down the bacteria into small bateria molecules (contains lysosmes and bacteria molecules)
6. Lastly the secondary lysosomes go to the cell membrane and release the bacteria molecule out through exocytosis.

Question 2

What happens in exocytosis?

Answer 2

1.DNA converts to mRNA( transciption) then the mRNA leave the nucleus through the nuclear pores
2.The vesicles will bind to the ribosomes on the R.E.R and it will go through its process e.g protein folding.
3.The vesicles leaves the ribsomes and has cop 2 which tells it to go to the golgi
4.The golgi goes through its process, then it spits out the vesicles and microtubules motor protein dyin and kinase use ATP to tell the vesicle where to go
5.Then v snare protein are on the vesicle and they intertwine with the t snare which will pull the vesicle down to the cell membrane and the protein or hormone is released.

Question 3

What are the three types of vesicular transport?

Answer 3

1. Pinocytes
2. Phagocytosis
3. Exocytosis
