B. Apaf-1
C. executioner caspases
D. FADD
Ans: C. Executioner caspase
Explanation: Caspase 3 is an example of executioner caspase. It takes part in both the intrinsic and extrinsic pathways of apoptosis. It is a protease enzyme and cleaves proteins in both types of apoptosis.

How can you generate a mouse that expresses a gene on demand as an adult mouse. none of the above using a tissue specific promotor to drive expression of a tetracycline response element and ubiquitous promotor to control expression of the gene of interest with lots of training using a tissue specific promotor to drive expression of a tetracycline reregulatory protein and a tetracycline response element to control expression of the gene of interest that is driven by a ubiquitous...
TRUE/FALSE 13.There are two pathways contributing to hemostasis: the extrinsic and intrinsic pathways. The extrinsic pathway utilizes chemicals that are released into the bloodstream only after blood vessels have been damaged 14. The CoaguChek S instrument uses samples obtained via capillary puncture, not tubes of blood collected via venipuncture. 15.INR results accompany Protime results, not D-dimer assays. 16.Coumadin may be used to treat patients who have experienced thrombosis as well as other conditions, such as atrial fibrillation, which increase the...
Depletion of cholesterol in the cell membrane using a drug (mevastatin) has been associated with apoptosis in cancer cells. a. What effect would cholesterol depletion have on the integrity of lipid rafts in the membrane? b. Researchers found that FAS death receptor was activated in cholesterol depleted cancer cells. Explain how activation of this receptor activates killer caspases. c. When a caspase is converted from its inactive to its active form there are changes in the primary and tertiary structure...
State whether each sentence is true or false. If it is false, cross out the incorrect word and write the correct word in its place. a) Apoptotic cells will express structures, such as the Fas death receptor, on their plasma membrane. _________ b) Bcl2 prevents cell death by inhibiting the actions of caspases. ___________ c) The binding of a survival factor to a membrane bound receptor stops the transcription of Bcl2. ___________ d) Assembly of the apoptosome is induced by...
