0.2 Movement In And Out Of Cells

Question 1

How does surface area to volume ratio affect the rate of movement of substances into and out of cells?

Answer 1

A larger surface area of the cell membrane allows more substances to pass through at once

Question 2

How do the effects of distance of the diffusion pathway affect the rate of movement of substances into and out of cells?

Answer 2

The shorter the distance substances have to travel, the faster they they move

Question 3

How do the effects of temperature affect the rate of movement of substances into and out of cells?

Answer 3

Higher temperatures give particles more energy, so they move faster due to more kinetic energy

Question 4

How does the effects of the concentration gradient affect the rate of movement of substances into and out of cells?

Answer 4

Substances move faster when there’s a big difference between concentrations inside and outside the cell
