MULTIPLE CHOICE
A STUDENT IS OBSERVING A CELL UNDER THE MICROSCOPE. IT IS OBSERVED TO HAVE SUPERCOILED
DNA WITH HISTONES. WHICH OF THE FOLLOWING WOULD ALSO BE OBSERVED BY THE STUDENT?
A SINGLE CIRCULAR CHROMOSOME A NUCLEUS
FREE-FLOATING NUCLEAR MATERIAL NO ORGANELLES
ANS: B
THE CELL DESCRIBED IS A EUKARYOTIC CELL, SO IT HAS HISTONES AND A SUPERCOILED DNA WITHIN ITS
NUCLEUS; THUS, THE NUCLEUS SHOULD BE OBSERVED. A SINGLE CIRCULAR CHROMOSOME CALLED A
PROKARYOTE CONTAINS FREE-FLOATING NUCLEAR MATERIAL BUT HAS NO ORGANELLES.
,REF: P. 2
A NURSE IS INSTRUCTING THE STAFF ABOUT CELLULAR FUNCTIONS. WHICH CELLULAR FUNCTION IS THE
NURSE DESCRIBING WHEN AN ISOLATED CELL ABSORBS OXYGEN AND USES IT TO TRANSFORM
NUTRIENTS TO ENERGY?
METABOLIC ABSORPTION COMMUNICATION SECRETION RESPIRATION
ANS: D
THE CELL’S ABILITY TO ABSORB OXYGEN IS REFERRED TO AS RESPIRATION WHILE ITS COMMUNICATION
ABILITY INVOLVES MAINTENANCE OF A STEADY DYNAMIC STATE, METABOLIC ABSORPTION PROVIDES
NUTRITION, AND SECRETION ALLOWS FOR THE SYNTHESIZING OF NEW SUBSTANCES.
REF: P. 2
A EUKARYOTIC CELL IS UNDERGOING DNA REPLICATION. IN WHICH REGION OF THE CELL WOULD MOST
OFTHE GENETIC INFORMATION BE CONTAINED?
MITOCHONDRIA RIBOSOME NUCLEOLUS
NUCLEUS CYTOPLASM
ANS: C
THE REGION OF THE CELL THAT CONTAINS GENETIC MATERIAL, INCLUDING A LARGE AMOUNT OF
RIBONUCLEIC ACID, MOST OF THE DNA, AND DNA-BINDING PROTEINS, IS THE NUCLEOLUS, WHICH IS
LOCATED WITHINTHE CELL’S NUCLEUS. MITOCHONDRIA IS ASSOCIATED WITH CELLULAR RESPIRATION,
WHILE RIBOSOMES ARE INVOLVED WITH PROTEIN MANUFACTURING. CYTOPLASM IS A FLUID FILLING
THAT IS A COMPONENT OF THE CELL.
REF: P. 2
WHICH OF THE FOLLOWING CAN REMOVE PROTEINS ATTACHED TO THE CELL’S BILAYER BY DISSOLVING
THELAYER ITSELF?
PERIPHERAL MEMBRANE PROTEINS INTEGRAL MEMBRANE PROTEINS GLYCOPROTEINS
CELL ADHESION MOLECULES
, ANS: B
PROTEINS DIRECTLY ATTACHED TO THE MEMBRANE BILAYER CAN BE REMOVED BY THE ACTION OF
INTEGRAL MEMBRANE PROTEINS THAT DISSOLVE THE BILAYER. PERIPHERAL MEMBRANE PROTEINS
RESIDE AT THE SURFACE WHILE CELL ADHESION MOLECULES ARE ON THE OUTSIDE OF THE MEMBRANE.
GLYCOPROTEIN MARKS CELLS AND DOES NOT FLOAT.
REF: P. 7
WHICH OF THE FOLLOWING CAN BIND TO PLASMA MEMBRANE RECEPTORS?
OXYGEN RIBOSOMES
AMPHIPATHIC LIPIDS LIGANDS
ANS: D
LIGANDS ARE THE ONLY SPECIFIC MOLECULES THAT CAN BIND WITH RECEPTORS ON THE CELL
MEMBRANE.
REF: P. 9
A NURSE IS REVIEWING A REPORT FROM A PATIENT WITH METASTATIC CANCER. WHAT ALTERNATION
IN THEEXTRACELLULAR MATRIX WOULD SUPPORT THE DIAGNOSIS OF METASTATIC CANCER?
DECREASED FIBRONECTIN INCREASED COLLAGEN DECREASED ELASTIN INCREASED GLYCOPROTEINS
ANS: A
ONLY A REDUCED AMOUNT OF FIBRONECTIN IS FOUND IN SOME TYPES OF CANCEROUS CELLS,
ALLOWING THEM TO TRAVEL OR METASTASIZE.
