C) Both D and E
D) Glucose molecules are transported against their concentration gradient.
E) Sodium ions are transported down their concentration gradient.
Cotransport
The active transport of a substance from a region of low concentration to a region of high concentration by coupling its transport to the transport of a substance down its concentration gradient.
Concentration Gradient
A gradual change in the concentration of solutes in a solution as a function of distance through a solution.
ATP
Adenosine Triphosphate, a molecule that stores and transfers energy within cells, crucial for many cellular processes.
- Acquire knowledge about the dynamics of membrane transport, distinguishing between passive and active transport techniques.
- Describe how cells maintain concentration gradients and the significance of these gradients.
