Question
Chapter 23, Problem 49P
Interpretation Introduction
Interpretation:
The symptoms of methylmalonic acidemia can become benign to fatal should be explained.
Concept introduction:
Proteasome is a composite of proteinases that are involved in the breakdown of specific intracellular proteins. ATP hydrolysis is a catabolic process that helps in releasing the chemical energy from the high-energy phospho-anhydride bonds in ATP. Energy is liberated by splitting these bonds.

2. For the flow of fluid over a flat membrane of length 10cm,
determine the length-average mass transfer coefficient. The
relevant properties of the system are u=0.01cm²/s, D=5 x 106
cm²/s, and v = 5.0 cm/s.
Background
Freezing isn't the only challenge in cryopreservation - thawing can
be just as difficult. A microwave oven seems like a nice solution,
since it deposits energy quickly and microwaves are non-ionizing
radiation (they do not cause DNA mutation). However, water
absorbs microwaves more effectively than ice does, meaning that
the portion of an organ that has already melted will get warmer at a
higher rate than the remaining ice – the opposite of what we want!
-
The transmission of radiation through a weakly absorbing material
such as ice or water can be modeled by Beer's law, which assumes
that the rate of absorption at a depth x is proportional to the local
radiation intensity I(x) times an absorption coefficient, which is often
written as μ or a or just µ). Noting that absorption decreases the
intensity, we can write a differential equation
a
Solving the differential equation with the boundary condition on the
surface being
gives the relationship

3. Dry air is inhaled at a rate of 10 liter/min through a trachea with
a diameter of 20 mm and a length of 125 mm. The inner
surface of the trachea is at a normal body temperature of 37°C
and may be assumed to be saturated with water.
a. Assuming steady, fully developed flow in the trachea,
estimate the mass transfer convection coefficient.
b. Estimate the daily water loss (liter/day) associated with
evaporation in the trachea.
