Question
A.
Assumed that the primary contributor to the absorbance of the sample
was due to the hemoglobins. Calculate how much red light the water in the sample absorbed.
Explain whether or not ignoring water was a reasonable assumption. (use image down below to solve)
B.
There are several membrane-bound organelles in cells (e.g. nuclei, mitochondria,
endoplasmic reticulum) that can also have ion channels in their membranes. Sketch an
electrical circuit model of a cell that expresses sodium, calcium, and chloride ion channels in its
cellular membrane and calcium and chloride ion channels in its nuclear envelope membrane.
