Q

Difference between eukaryotic and prokaryotic cells

A

Prokaryotic has no nucleus (DNA in nucleoid), Eukaryotic have membrane bound organelles, prokaryotic are smaller (simpler)

31
Q

Cellular membrane structure

35
Q

Passive Transport

A

Diffusion down electrochemical gradient

36
Q

Facilitated Diffusion

A

Aid by transport proteins (channel - gate activated, carrier - move through change in shape)

37
Q

Active Transport

A

Powered by ATP hydroolysis

38
Q

Cotransport

A

Coupling of transportation (symport - moving in direction, antiport - moving against)

39
