QUESTIONS AND ANSWERS
which two cellular organelles in eukaryotes have both electron transport systems and
chemiosmotic mechanisms? - Correct Answers -c. chloroplast and mitochondria
the manner in which several different ions and molecules move through a cell
membrane is shown in the diagram above. for each ion or molecule, the relative
concentration on each side of the membrane is indicated. which of the following
accurately describes what are the move it's taking place? - Correct Answers -d. Na+
transport out of the cell requires ATP hydrolysis
which of the following best predicts the effect of not having ATP available to supply
energy to this process? - Correct Answers -A. H+ ions will stop moving through the
protein
which of the processes is most likely to occur as a result of an animal cell receiving a
signal to initiate apoptosis? - Correct Answers -c. lysosomes will release digestive
enzymes into the cytosol
if ATP break down (hydrolysis) is inhibited, which of the following types of movement
across cell membranes is also inhibited? - Correct Answers -c. passage of a solute
against its concentration gradient
which of the following components of the cell membrane is responsible for active
transport? - Correct Answers -b. protein
in an experiment, the efficiency of oxygen across a plasma membrane is being
assessed in four artificial red blood cells. the table above list of properties of those
artificial cells. Other conditions being equal, which artificial cell is predicted to be the
most efficient in exchanging oxygen with environment by diffusion? - Correct Answers -
a. the cuboidal cell
play at cell walls are composed of cellulose, while fungal cell walls are composed of
chitin. A group of scientist hypothesize that this different speeds the cell wall has largely
different functions in plant cells and fungal cells. alternatively another group of scientist
hypothesize that despite their bio chemical differences, play in fungal cell wall serve
similar functions. Which of the following observations would best support the alternative
