1. A student is observing a cell under the microscope. It is observed to have
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



supercoiled DNAwith histones. Which of the following would also be observed by
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



the student?
tekr tekr



a. A single circular chromosome tekr tekr tekr



b. A nucleus tekr



c. Free-floating nuclear material tekr tekr



d. No organelles tekr




ANS: B tekr



The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



within itsnucleus; thus, the nucleus should be observed. A single circular
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



chromosome called a prokaryote contains free-floating nuclear material but has no
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



organelles.

2. A nurse is instructing the staff about cellular functions. Which cellular function is the
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



nurse describing when an isolated cell absorbs oxygen and uses it to transform
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



nutrients to energy?
tekr tekr tekr



a. Metabolic absorption tekr



b. Communication
c. Secretion
d. Respiration
ANS: NURSINGTB.COM
t D e k r



The cell’s ability to absorb oxygen is referred to as respiration while its communication
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



abilityinvolves maintenance of a steady dynamic state, metabolic absorption provides
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



nutrition, and secretion allows for the synthesizing of new substances.

3. A eukaryotic cell is undergoing DNA replication. In which region of the cell would
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



tekr most ofthe genetic information be contained?
tekr tekr tekr tekr tekr tekr



a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus Cytoplasm tekr




ANS: C tekr



The region of the cell that contains genetic material, including a large amount of
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



ribonucleicacid, most of the DNA, and DNA-binding proteins, is the nucleolus,
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



which is located withinthe cell’s nucleus. Mitochondria is associated with cellular
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



respiration, while ribosomes are involved with protein manufacturing. Cytoplasm is a
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



fluid filling that is a component of the cell.

4. Which of the following can remove proteins attached to the cell’s bilayer by
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



tekr dissolving thelayer itself? tekr tekr tekr



a. Peripheral membrane proteins tekr tekr



b. Integral membrane proteins tekr tekr

d. Cell adhesion molecules tekr tekr




ANS: B tekr



Proteins directly attached to the membrane bilayer can be removed by the action of
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



integralmembrane proteins that dissolve the bilayer. Peripheral membrane proteins
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



reside at the surface while cell adhesion molecules are on the outside of the
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



membrane. Glycoprotein marks cells and does not float.

tekr tekr tekr tekr tekr tekr tekr tekr tekr



a. Oxygen
b. Ribosomes
c. Amphipathic lipids tekr



d. Ligands
ANS: D tekr



Ligands are the only specific molecules that can bind with receptors on the cell

contact?
tekr



a. Cell junction tekr



b. Gap junction tekr

ANS: A tekr



Cell junctions hold cells together and permit molecules to pass from cell to cell.
tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr tekr



Gap junctions allow for cellular communication between cells. Neither desmosomes nor
