The density of the plasma membrane of a cell was found to be
1.07 g/mL. If the density of the lipid component is 0.91 g/mL and
the density of the protein component is 1.36 g/mL, what is the
percent composition (to the nearest ones) of the lipid component of
the membrane, assuming the plasma membrane consists only of the
lipid and protein components?

The density of the plasma membrane of a cell was found to be
1.04 g/mL. If the density of the lipid component is 0.92 g/mL and
the density of the protein component is 1.35 g/mL, what is the
percent composition (to the nearest ones) of the lipid component of
the membrane, assuming the plasma membrane consists only of the
lipid and protein components?
Plasma Membrane. What is the composition of
plasma membrane (PM) of a bacterial cell? How does this compare to
a eukaryotic cell? List the functions of the PM. Without complex
internal membranes, where do prokaryotes carry out membrane-bound
chemical reactions such as ATP synthesis or photosynthesis?
Imagine a genetic defect that affects embedded proteins within
the cellular membrane (assume that somehow this condition is
compatible with life). Which forms of cell membrane transport would
be affected by this disease, and which forms of cellular transport
would proceed unaffected? Be sure to include rationale for your
inclusion of each type of cell membrane transport in its respective
category.
Suppose that a molecular ion with charge -10e is
embedded within the 5.0-nm-thick cell membrane of a cell with
membrane potential -70 mV.
What is the electric force on the molecule?
