NLN PAX Biology Exam Questions With
Complete Solutions
Cell - CORRECT ANSWER✔✔-smallest living unit and the basic unit of function and
structure for all living things.
Nucleus - CORRECT ANSWER✔✔-contains genetic information or DNA, controls
the activities of the cell.
DNA - - CORRECT ANSWER✔✔-Deoxyribonucleic Acid - genetic information.
Plasma or Cell Membrane - CORRECT ANSWER✔✔-Semipermeable membrane
that separates the contents of the cell from the surrounding fluids (interstitial
fluid).
Interstitial Fluid - CORRECT ANSWER✔✔-contains substances such as aminoacids,
sugars, fatty acids, hormones, neurotransmitters and salts.
Selectively permeable or semi permeable membrane - CORRECT ANSWER✔✔-
refers to the selective nature of the plasma membrane. It contains pores and
channels that allow only particles of the right size or right chemical nature to pass
through. Additionally plasma membrane contains receptors that bind with specific
substances, thus allowing special entry or signals to the cell to perform a certain
activity.
, Cytoplasm - CORRECT ANSWER✔✔-Fluid matrix found between the plasma
membrane and the nucleus that act as scaffolding for the organelles.
Organelles - CORRECT ANSWER✔✔-or "little organs" are specialized units in the
cell that perform certain functions.
Mitochondria - CORRECT ANSWER✔✔-are the locations for cellular respiration
that is the conversion of food to energy at the cellular level, thus the mitochondria
are the sites of energy production and most of its ATP.
ATP - CORRECT ANSWER✔✔-adenosine triphosphate - chemical the cell uses to
store and transfer energy within itself.
Ribosome - CORRECT ANSWER✔✔-site of protein synthesis in the cell.
Endoplasmatic Reticulum(ER) - CORRECT ANSWER✔✔-serves as means of
transport within the cell and is made up of many channels.
Rough ER - CORRECT ANSWER✔✔-named for the fact that it has ribosomes on its
surface, serves to store and deliver proteins made by the attached ribosomes.
Smooth ER - CORRECT ANSWER✔✔-Free of ribosomes, found in a variety of cells,
performs varying functions in different cells, including the storage of enzymes and
