Question
Chapter 7.8, Problem 23WDYL
Summary Introduction
To explain:
The risk of bearing weight on a bone when the fibrocartilage callus is forming.
Concept introduction:
The bones have great strength and rigidity, but the bones can break due to sudden actions, or due to some diseases. The fractures are divided into simple and compound, on the basis of severity of fractures.

QUESTION 9
An animal cell has been wounded and has a small rupture in its plasma membrane. Which of the following is more likely to happen next?
OA. The cell rapidly cleaves by cytokinesis.
OB. The rate of receptor-mediati endocytosis is increased.
OC. The rate of exocytosis is increased.
OD. The rate of pinocytosis is increased.
For the a subunit of a trimeric G protein,
A. a G-protein-coupled receptor GPCR) acts as a guanine nucleotide exchange factor (GEF), whereas a regulator of G protein signaling (RGS) can act as a GTPase-activating protein
(GAP).
B. a GPCR acts as a GAP, whereas an RGS can act as a GEF.
C. both a GPCR and an RGS can act as a GEF.
O D. both a GPCR and an RGS can act as a GAP
OE. None of the above.
A cell expresses a transmembrane protein that is cleaved at the plasma membrane to release an extracellular fragment. The fragment binds to receptor proteins on nearby cells and
activates signaling pathways resulting in altered gene expression patterns in the cells. What form of intercellular signaling does this represent?
OA. Contact-dependent signaling
B. Paracrine signaling
OC. Synaptic signaling
D. Endocrine signaling
E. Autocrine signaling
