Here is the answer...hope it helps:)
Answer:
B. It inhibits the extrinsic pathway of apoptosis
Explanation:
Apoptosis is a cellular pathway that leads to programmed cell death. Viral FLICE-inhibitory proteins (FLIPs) bind to the adaptor proteins and block the interaction between the DISC complex with the caspase-8 protease enzyme, which triggers apoptotic cell death. In consequence, cells become resistant to Fas-mediated apoptosis, a pathway initiated by the FADD protein which is known to recruit caspase-8.
<u>Answer:</u>
c) phosphorylation of cellular proteins.
<u>Explanation:</u>
Background Knowledge:
Kinase Enzymes:
These are the enzyme which speedup the transfer of phosphate groups from high energy, phosphate-donating molecules like ATP to specific substrates. This process of phosphate donation from high energy molecules to specific substrate is known as phosphorylation.
Protein Kinases:
Protein kinases are the type of kinases which transfer phosphate group from high energy phosphate donating molecules to the proteins.
so correct answer of this question is c) phosphorylation of cellular proteins.
Animal cells have a cell membrane and not a cell wall. They have ribosomes and lysosomes and their nucleus is enveloped by a nuclear membrane. This means that the first description;
Cell membrane present;
ribosomes present;
lysosomes present;
nuclear membrane present.
Matches ANIMAL.
Plant cells on the other hand have something called a cell wall, which are more rigid than cell membranes. Plant cells are known for their large vacuole. They also have a nuclear membrane that covers its nucleus.
The third description:
Cell wall present
Ribosomes present
Nucleus present
Large vacuole present
Matches PLANT.
Viruses do not have any membrane on its wall nor its nucleus. Basically, they have no internal structures. The fourth and last description:
Reproduces inside of a cell
Nucleus absent
RNA present
Matches VIRUS
Prokaryotes are primitive cells and they do have a cell wall but they have no defined nucleus, which means they do not have a nuclear membrane. The second description:
Cell wall present
Ribosomes present
Nuclear membrane absent
Matches PROKARYOTE
