|
Do yeast cells transport maltose across the plasma membrane by facilitated diffusion, direct active transport, or indirect active transport?
|
Indirect Active Transport or Symport
|
|
|
What does the transport lab use to measure the uptake rate of maltose?
|
The non-radiolableled substrate NPG.
|
|
|
What make it possible for us to use NPG to measure the rate of uptake of maltose?
|
the fact that NPG produces a colored product when hydrolyzed.
|
|
|
What happens to NPG once it makes its way into the cell the same way maltose is transported into the cell?
|
It is rapidly hydrolyzed
|
|
|
Why can the rate of hydrolysis product generation can be used as an indicator of rate of transport?
|
because the rate of intracellular hydrolysis of NPG is faster than the rate of transport
|
|
|
What effect does pH have on transport? What does this tell us about the transport mechanism of maltose?
|
None. This tells us that
|
