Q. 15.65 - An Introduction to General, Organic, and Biological Chemistry

Question

Identify the type of transport described by each of the following:

a. A molecule moves through a protein channel.

b. ${\mathrm{O}}_2$ moves into the cell from a higher concentration outside the cell.

Step-by-Step Solution

Answer

(part a) The transportation of a monomer via a cell membrane. 

(part b) The oxygen transfer from an upper to the lower intensity. 

Step 1: Introduction (part a)

The movement or diffusion of molecules throughout the channel is promoted by the concentration difference, and diffusion of atoms is carbon neutral.

Step 2: Given Information (part a)

Nonpolar compounds might flow freely over the bilayer. Molecules and interfacial exchanges flow penetrate cell membranes with easily.

Step 3: Explanation (part a)

(a) Facilitated transport: That form of transport comprises the use of surface proteins to convey components. Guided dispersal or assisted diffusion is the transportation of a monomer via a cell membrane.

Step 4: Given Information (part b)

Small complex compounds, such as glycosidic bonds, are redistributed more easily by transport mechanism.

Step 5: Explanation (part b)

(b) Simple inactive transport is represented by that of the oxygen transfer from an upper to the lower intensity.
