Movment In and Out Of Cell

Question 1

What is a diffusion

Answer 1

Movment of particles from their high concentration to their low concentration down a concentration gradient

Question 2

Factors affect rate of movment

Answer 2

High temperature will increase rate of movment so more energy so more kinetic energy so particles move faster
High concentration gradient will increase rate if movment
Shorter diffusion distance will increase rate of diffusion
Large surface area to volume ratio will increase rate of movment

Question 3

What is active transport

Answer 3

Movment of molecules from thier lower concentration to their higher concentration against concentration gradient using energy from respiration

Question 4

What is a passive process

Answer 4

Doesn’t consume metabolic energy

Question 5

Active process

Answer 5

Consume metabolic energy

Question 6

What is osmosis

Answer 6

It’s movment of water molecules from higher water potential to low water potential through a partially permeable membrane

Question 7

Difference between osmosis and diffusion and active transport

Answer 7

Diffusion passive, doesn’t require energy,moves substances down a concentration gradient,moves substances from high to a low concentration, osmosis, passive, doesn’t require energy,moves substances down a concentration gradient,moves substances from a high to low concentration
Movment of water only, active transport,requires energy,moves molecules against a concentration gradient, moves substances from a low to high concentration
