- List two ways that channels differ from transporters? What type of molecules do channels usually transport?"Transporters saturate at high concentrations of the transported molecule when all their binding sites are occupied; channels, on the other hand, do not bind the ions they transport and thus the flux of ions through a channel does not saturate." is true or false.Describe the difference between carrier proteins and channel proteins. What is required for the passive transport of molecules through these membrane proteins?
- Why "Transporter are not very selective, and allow solutes to enter or leave the cell through channels or carriers composed of proteins" is true"?An important process for membrane formation is the phase inversion process. Which parameters have a large influence on the membrane morphology and why?Without saturation of transport proteins and under the same concentration gradient how can the speed of simple diffusion be compared to the speed of facilitated diffusion?
- What is the Direction of net flux Through Protein Channel?"Transport by transporters can be either active or passive, whereas transport by channels is always passive" is true or false.A migraine fish would be rapidly transferring substances across cell membrane. The substances would include sodium, water, carbon dioxide, oxygen, and steroids. Which of those would most likely be moved via active transport? Why?
