Worked Solution & Example Answer:What is happening at position 3? - Enzymes that break down the microorganism are released into the vesicle - VCE - SSCE Biology - Question 20 - 2019 - Paper 1
Step 1
Enzymes that break down the microorganism are released into the vesicle.
Answer
At position 3, enzymes are released into the vesicle. These enzymes play a crucial role in degrading the microorganism, breaking it down into smaller, manageable components. This process is essential for the subsequent clearing of the pathogen.
Step 2
Antibodies are added to the vesicle to kill the microorganism.
Answer
Additional to enzyme activity, antibodies are incorporated into the vesicle. These antibodies specifically bind to the microorganism, marking it for destruction and enhancing the immune response by aiding in pathogen neutralization.
Step 3
The cell is sampling the vesicle for antigen presentation.
Answer
The cell is actively sampling the contents of the vesicle. This process is vital for antigen presentation, where fragments of the microorganism are displayed on the cell surface to alert other immune cells, triggering a broader immune response.
