Which of the following structures is embedded in the cell
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
membrane to facilitate the movement of molecules across the
i,- i,- i,- i,- i,- i,- i,- i,- i,-
membrane?
a) proteins
i,-
b) ATP
i,-
c) glucose
i,-
d) lipids
i,- a) proteins: embedded in the cell membrane are
i,-i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
integral to many cell functions, including active transport and
i,- i,- i,- i,- i,- i,- i,- i,- i,-
some types of passive transport

A student places a cell with 50 mM intracellular ion content into a
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
solution containing a 20 mM ion content. which of the following
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
will happen in this system?
i,- i,- i,- i,-
a) water will move out of the cell, decreasing the size of the cell
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
b) water will move into the cell, increasing the size of the cell
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
,c) ions will move into the cell
i,- i,- i,- i,- i,- i,-
d) there will be no movement of water or ions across the cell
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
membrane b) water will move into the cell, increasing the
i,-i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
size of the cell: the concentration of ions is higher inside the cell
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
than outside, so water will move into the cell from the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
environment, increasing the size of the cell i,- i,- i,- i,- i,- i,-
Which of the following substances cannot travel across a cell
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
membrane without the use of energy? i,- i,- i,- i,- i,-
a) water
i,-
b) potassium
i,-
c) sodium
i,-
d) glucose
i,- d) glucose: a glucose molecule is too large to pass
i,-i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
through the cell membrane without the help of specialized
i,- i,- i,- i,- i,- i,- i,- i,- i,-
proteins
All of the following molecules are used in the Calvin Cycle EXCEPT
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
a) O2
i,-
b) CO2
i,-
c) ATP
i,-
, d) NADPH
i,- a) O2: is released during the light-dependent
i,-i,- i,- i,- i,- i,- i,- i,- i,- i,-
stage of photosynthesis and is not used during the Calvin Cycle.
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
the other choices are used during the Calvin Cycle to produce
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
glucose
Which of the following stages of cellular respiration produces the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
largest number of ATP molecules? i,- i,- i,- i,-
a) glycolysis
i,-
b) fermentation
i,-
c) Krebs cycle
i,- i,-
d) electron transport chain
i,- d) ETC: produces 30-32 molecules i,- i,- i,-i,- i,- i,- i,- i,- i,- i,-
of of ATP made during cellular respiration. the other choices each
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
produce only two molecules of ATP i,- i,- i,- i,- i,-
A scientist takes DNA samples from a cell culture at two different
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
times, each same having the same cell count. in the first sample,
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
he finds that there is a 6.5 pg of DNA whereas in the second
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
sample, he finds that there is a 13 pg of DNA. which state of the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
cell cycle is the first sample in?
i,- i,- i,- i,- i,- i,-
