2. Which of the following is correct about a G protein coupled receptor?
A) It is activated by attaching to a GTP
B) It activated a G protein by attaching a GTP to it
C) It needs to be dimerized to be fully functional.
D) Once it is activated, it is constitutively active: B) It activated a G protein by attaching a GTP
to it
3. Which of the following is a long distance signaling?

,D) Signaling through junctions: B) Endocrine signaling
4. Which of the following statements is correct about cell cycle?
A) Bacterial cell division is called mitosis
B) Cells are always dividing and go through the cell cycle nonstop.
C) Mitosis is the cell division that results in daughter cells that have the same
chromosomes as the parent cells have.
D) Meiosis is the cell division that results in daughter cells that have the same
chromosomes as the parent cells have.: C) Mitosis is the cell division that results in daughter cells

5. Which receptor is NOT a membrane protein receptor?
A) G protein coupled receptor
B) Calcium ion channel receptor
,C) Intracellular receptor
D) Receptor tyrosine kinase: C) Intracellular receptor
6. Which of the following statements is correct about how cyclins and Cdk
regulate cell cycle?
A) Accumulation of Cdk phosphorylates cyclins
B) Accumulation of cyclins leads to activation of Cdk, which allows DNA dupli-
