Question

5 matching 1 point what is likely to happen in the following scenarios? nacl concentrations are lower inside the cell than outside, causing water to move and the concentration to change. glucose is in excess in the space surrounding the cell. a cell has more oxygen gas outside of the cell than inside. glucose is high inside the cell, but the cell needs an even higher concentration of it. 6 multiple choice 1 point

Explanation:

1. When NaCl concentrations are lower inside the cell than outside causing water to move, it's osmosis (a type of passive transport). Osmosis is the movement of water across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
2. When glucose is in excess in the space surrounding the cell, it will move into the cell by passive transport (facilitated diffusion if it requires a carrier protein). Facilitated diffusion is a type of passive transport where molecules move down their concentration gradient with the help of transport proteins.
3. When there is more oxygen gas outside of the cell than inside, oxygen will move into the cell by passive transport (diffusion). Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.
4. When glucose is high inside the cell but the cell needs an even higher concentration of it, active transport (pumps) is required as it moves molecules against their concentration gradient using energy.

Answer:

1. Passive Transport (osmosis)
2. Passive Transport (facilitated diffusion)
3. Passive Transport (diffusion)
4. Active Transport (pumps)
