In the epidermis, there were scattered dead epidermal cells that hadrounded contours and pyknotic nuclei. This form of cell death is caused bya.activation of caspases through receptor transmitted signals on the cell surfaceb.inhibition of ATPasec.inhibition of oxidative phosphorylationd.activation of lysosomal enzymese.depletion of glycogenANS:A,Graft-versus-hostinduced cell death in the epidermis is a form of apoptosis. It ismediated by caspases and other enzymes of the suicide pathway of "programmed cell death."3.Uptake of bacteria into the cytoplasm of neutrophilic leukocytes is calleda.autophagocytosisb.heterophagocytosisc.exocytosisd.pinocytosise.involutionANS:B,Uptake of bacteria and other exogenous particulate material into the phagosomes iscalled phagocytosis.
