Question

Select the pathway that would lead to the activation of cytotoxic T cells. A. B cell contact antigen \rightarrow helper T cell is activated → clonal selection occurs B. body cell becomes infected with a virus → new viral proteins appear \rightarrow class I MHC molecule-antigen complex displayed on cell surface C. complement is secreted →B cell contacts antigen → helper T cell activated → cytokines released D. cytotoxic T cells → class II MHC molecule-antigen complex displayed → cytokines released \rightarrow cell lysis

Answer 1

The pathway that would lead to activation of cytotoxic T cells includes body cell that becomes infected with new virus entry.

What is the role of Cytotoxins in the entry of a new viruses?

Cells can die in one of two ways.

Physical or chemical damage causes cell disintegration or necrosis.

• One such example is the lack of oxygen in the cardiac muscle during a heart attack or the damage produced by antibodies and complements.
• Phagocytic cells collect and destroy dead or necrotic tissue, cleaning the wounded tissue and repairing the lesion gradually.
• The other form of cell death is apoptosis or intentional cell death.
• Apoptosis is a normal cellular response that is essential for tissue remodelling throughout development and metamorphosis in all multicellular animals.

Hence, the correct answer is option B
