types of diffusion

Question 1

simple diffusion

Answer 1

requires no energy, goes with the concentration gradient, no channel protein is required, water, oxygen, carbon dioxide can travel through bi layer with simple diffusion, non polar

Question 2

facilated diffusion

Answer 2

no energy is required, goes with the concentration gradient, for larger polar molecules, protein channel is required

Question 3

active transport

Answer 3

enegry is required, goes against the gradient, and requirement of input atp

Question 4

phosopholipid bi layer

Question 5

what is a hydophilic component of phospholipid bi layer

Answer 5

the phosphate head is hydrophilic

Question 6

what is a hydrophobic component of the bi layer?

Answer 6

fatty acid tail is hydrophobic

Question 7

difference between how cells travel with active transport and facilated diffusion?

Answer 7

facilitated: moves with the help of glycoproteins, that allow molecules to pass through. located at the top of bi layer

Active Transport: atp pump is used

Question 8

types of molecules and how they travel through membrane

Answer 8

water= facilitated diffusion, hydrophilic

oxygen= simple diffusion, hyrdophobic

Question 9

pinocytosis

Answer 9

bulk movement of fluids

Question 10

phagocytosis

Answer 10

bulk movement of solids

Question 11

draw the order of binary fission on paper
