Molecular Cell Biology Exam
questions and answers graded A+
Fundamental unit of life, all contain genetic information, written in the same language (DNA) and
this information flows in a similar fashion with central dogma theory, cells have different forms,
functions, and requirements - ANS✅✅cells
cellular structure, relied heavily on microscope - ANS✅✅cytology
structure and function of biological molecules, chemical processes occurring in living things -
ANS✅✅biochemistry
genes/heredity - ANS✅✅genetics
cytology, biochemistry, genetics, science is interdisciplinary - ANS✅✅what is cell biology?
discovered the microscope in the 17th century, visualize living cells, call cells "cellulae" -
ANS✅✅Robert Hooke
all living organisms are composed of 1 or more cells, cells are the basic unit of life, plasm membrane
allows metabolism, cells arise from pre-existing cells - ANS✅✅cell theory
Prokaryotic cells do not have a nucleus and no membrane bound organelles like a studio apartment,
eukaryotic cells have membrane bound organelles and a nuclues - ANS✅✅prokaryotic vs
eukaryotic cells
both need membrane, genetic information, ribosomes, cytoplasm - ANS✅✅prokaryotic and
eukaryotic similarities
stores information, enclosed by nuclear membrane, control center - ANS✅✅nucleus
site of cellular respiration, where the bulk of the ATP is synthesized - ANS✅✅mitochondria
, photosynthesis- converting solar energy to chemical energy - ANS✅✅Chloroplast
inactivates toxic molecules, broken down generates H2O2 (hydrogen peroxide) -
ANS✅✅peroxisome
storage and digestion, majority of plant cell that makes cells look full - ANS✅✅Vacuole
ribosomes are associated with the surface- site of some protein synthesis - ANS✅✅Rough ER
no ribosomes, site of lipid synthesis - ANS✅✅smooth ER
modifies and packages molecules from the ER - ANS✅✅golgi apparatus
shuttles material, import and export - ANS✅✅vesicles
small organelle where intercellular digestion occurs similar to peroxisome - ANS✅✅lysosomes
"bones of the cell" governs internal organization and external features, movement like muscle
contraction, division (microtubules pull chromosomes apart, structure, cellular highway -
ANS✅✅Cytoskeleton
cytoplasm- contents of the cell within the plasma membrane except the nucleus
cytosol- contents of cytoplasm except membrane bound organelles - ANS✅✅cytoplasm vs cytosol
A theorized process in which early eukaryotic cells were formed from simpler prokaryotes where one
cell engulfed another, evidence is in genetic material from mitochondria and chloroplast -
ANS✅✅Endosymbiosis
false - ANS✅✅true or false: plants do not require a cytoskeleton because they have a cell wall that
lends structure and support to the cell
false - ANS✅✅true or false: the cytosol is fairly empty, containing a limited number of organelles
which allows room for rapid movement via diffusion
