Mastering Biology Ch. 7 (From the Ch.7 tutorial on MB)
Questions With Complete Solutions
A membrane-enclosed sac of hydrolytic enzymes found in the
cytoplasm of eukaryotic cells. Correct Answers lysome
A protein that binds selectively to a specific molecule (such as
an intercellular mediator or antigen) and initiates a biological
response. Correct Answers receptor
A three-dimensional biological polymer constructed from a set
of 20 different monomers called amino acids. Correct Answers
protein
A tiny membranous sac in a cell�s cytoplasm carrying
molecules produced by the cell. Correct Answers transport
vesicle
An organelle in eukaryotic cells consisting of stacks of flat
membranous sacs that modify, store, and route products of the
endoplasmic reticulum. Correct Answers golgi aparatus
autophagy is done by Correct Answers lysosome
Basal bodies and centrioles have Correct Answers identical
structures
Bound (free) ribosomes synthesize which three proteins?
Correct Answers ER protein, insulin, lysosomal enzyme
bound ribosomes make proteins destined for locations separated
from the cytoplasm by a cellular membrane Correct Answers
