Which of the following processes requires the cell to expend metabolic energy directly (e.g., from ATP)? (a) osmosis (b) facilitated diffusion (c) all forms of carrier-mediated transport (d) active transport (e) simple diffusion
A research student creates an artificial animal cell containing a 5M solution of glucose with a selectively permeable membrane that only allows water to cross it. She places the cell into a beaker of water. After an hour, what effect do you expect to observe? (a) Water moves out of the cell causing it to shrink. (b) Glucose moves out of the cell until equilibrium is reached. (c) Water moves into the cell causing it to lyse/burst. (d) Glucose moves into the cell by facilitated diffusion. (e) There is no net movement of water or glucose. Explain your answer
Part 1: If a gated channel (not a pump) is specific for potassium ions and based on what you know about concentration gradients, when will the potassium ions move through the channel?
a) Is gated channel transport using energy (ATP)?
Part 2: Why does the sodium - potassium pump need to use energy (ATP)?
a) Define active transport in your own words.
