Question 9 of 22

1

Which of the following definitions is incorrect?

Select one of the following:

  • Uptake- picking up of the antigen from surrounding fluid

  • Degredation- total digestion of the antigen

  • Presentation- movement of the complex to the cell surface

Explanation

Question 10 of 22

1

Endosomal Pathway- What is it for?

Select one of the following:

  • Processing of extracellular antigens picked up by antigen presenting cells

  • Processing of cytosolic viral antigens

Explanation

Select one of the following:

  • True
  • False

Explanation

Question 12 of 22

1

Endosomal Pathway- The extracellular antigen is picked up by phagocytosis

Select one of the following:

  • True
  • False

Explanation

Question 13 of 22

1

Endosomal Pathway- How is picking up of the antigen mediated?

Select one or more of the following:

  • Receptor mediated

  • Compliment mediated

  • Hormone mediated

Explanation

Question 14 of 22

1

Endosomal Pathway- The antigen containing endosome only binds to the MCHII containing endosome after partial digestion

Select one of the following:

  • True
  • False

Explanation

Question 15 of 22

1

Endosomal Pathway- How is the active site of MHCII covered in the cell?

Select one of the following:

  • Covered by an invariant 'cap'

  • The two parts are connect by a subunit that must be removed

  • Receptor surface is bound to the endosome envelope

Explanation

Question 16 of 22

1

Endosomal Pathway- The cover of the MHC complex is called a CLIP

Select one of the following:

  • True
  • False

Explanation

Question 17 of 22

1

Endosomal Pathway- How is the processed antigen added to the MHCII complex?

Select one of the following:

  • Acessory proteins swap the CLIP for the peptide when the two vesicles fuse

  • Acessory proteins remove the MHCII from the envelope when the two vesicles fuse

  • Acessory proteins remove the subunit connecting the two halves when the two vesicles fuse

Explanation

Question 18 of 22

1

Endogenous Pathway- Main use is for what?

Select one of the following:

  • Viral antigen processing

  • False

Explanation

Question 20 of 22

1

Endogenous Pathway- How are cytosolic antigens processed?

Select one of the following:

  • By the TCR

  • By MHCI

  • By cytosolic proteases

Explanation

Question 21 of 22

1

Explanation

Question 22 of 22
