Why is glucose in both diffusion and mediated diffusion?
Why is glucose in both diffusion and mediated diffusion?
Answer: Glucose uses Gluts and is metabolized in the cytosol immediately therefor glucose always remains lower than extracell concentrail (downhill gradient) therefore No energy.

Carrier Mediated diffusion is aka
Carrier Mediated diffusion is aka
Answer: facilitated diffusion
T/F You can increase the Flux of Mediated transport by increasing the amount of solute.
T/F You can increase the Flux of Mediated transport by increasing the amount of solute.
Answer: False: flux depends on how quickly the transporter can change shape.
