Concept explainers
(a)
Interpretation:
Amino acids which are more affected by light-dark adaptation.
Concept introduction:
Amino acid synthesis is the process in which amino acids are produced. The substrates of such processes are involved in a person’s diet or in the body itself. All living beings cannot synthesize all amino acids. Out of the 20 amino acids, humans can synthesize 11 amino acids only.
(b)
Interpretation:
Biochemical explanation for the observations.

- 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.arrow_forward1. Conceptual questions a. What dimensionless group describes the relative importance of convection versus diffusion. Explain the physical basis of this group. b. For mass transfer from a flowing fluid to a reactive surface, explain how convection increases the flux of solute to the surface.arrow_forwardAssessment +1501 pts /1600 Resources Solution ?
