Textbook Question
Chapter 5, Problem 6RQ
A cotransporter is a protein that moves more than one molecule at a time. If the molecules are moved in the same direction, the transporters are called __________ carriers; if the molecules are transported in opposite directions, the transporters are called __________ carriers. A transport protein that moves only one substrate is called a(n) __________ carrier.

- List the means of unassisted membrane transport.arrow_forwardIn biological systems, an ACTIVE transport process is one in which an important chemical component is moved from where it is in concentration, to where it is in concentration. Meanwhile, a PASSIVE transport (or diffusion) process is one in which an important chemical component moves from where it is in concentration to where it is in concentration. A FACILITATED transport process is a form of transport, where an important chemical component moves with the aid of a channel or similar structure. One specific example of a facilitated transport structure in the cell membrane is which aids in the movement of a particular chemical component, namelyarrow_forwardThe transport of a molecule is investigated using two chambers (left and right) separated by a synthetic membrane containing transport proteins. A solution containing varying concentrations of the molecule is added to the left side while pure water is added to the right. The transport rate of the molecule is determined by measuring the concentration of molecule that accumulates on the right side. The following table summarizes the transport rate of the molecule at various concentrations. Based on this you can conclude: a) the molecule is most likely transported by facilitated diffusion b) the molecule is moving across the membrane by passive transport c) the membrane is freely permeable to the molecule d) the molecule is most likely transported by active transportarrow_forward

Classify the molecules or ions depending on how they cross a biological membrane. Note that some of these examples may also utilize active transport to traverse a membrane. However, this question is limited to passive transport processes only. Ca²+ Simple Diffusion CO₂ fatty acids glucose Answer Bank steroid hormones Facilitated Diffusionarrow_forward
