COMPREHENSIVE TEST PAPER QUESTIONS
AND SOLUTIONS
◉ What is active transport.
Answer: the movement of ions or molecules across a cell membrane
into a region of higher concentration, assisted by enzymes and
requiring energy.
◉ List the three organelles, in order, involved in the synthesis,
transport, and shipping of proteins..
Answer: ribosomes, rough ER, golgi complex
◉ Be able to identify cell parts including the nucleus, ribosomes,
nucleolus, lysosomes, mitochondria, and the golgi apparatus.
Answer: T
◉ T/F cellular respiration occurs in the mitochondria.
Answer: True
◉ T/F the purpose of cellular respiration is to produce ATP.
Answer: True
, ◉ Integral proteins are only found on the inner surface of a cell
membrane. (T or F).
Answer: False, peripheral proteins are found on the inner or outer
surface of the cell membrane. Integral proteins span the entire
length of the membrane
◉ Endocytosis is the process that occurs to eject biomacromolecules
from the cell. (T or F).
Answer: False- (This process is called exocytosis)
◉ Pinocytosis uses a signaling molecule from another cell, binding
to the cell membrane to bring about changes within the cell proteins.
(T or F).
Answer: False- (This process is called receptor-mediated
endocytosis or information transfer)
◉ In your own words, discuss Tay-Sachs disease. What organelle
within the cell is impacted? What are the symptoms of the disease
and why do they occur?.
Answer: (1)Lysosomes(2) buildup of toxic lipids inside the cell
(biomacromolecules)(3) disability and deathIn the genetic disease
known as Tay-Sachs, one of the normally present digestive enzymes
inside lysosomes is lacking. Thus, a toxic lipid in the brain cells
