What happens in PROPHASE?
??mnemonics??
DPP
Nucleus and nuclear envelope disappears

Diffusion/Passive transport
Active Transport
Spontaneous mvt of molecules from higher to lower areas of concentration (O2 & CO2)
Simple Diffusion
It uses carrier proteins (glucose & amino acids)
Facilitated Diffusion - Carrier Mediated
Uses chemicals (Ach - Ach & Ach binding receptors)
Facilitated Diffusion - Channel Mediated - Ligand Gated
Uses electrical current (action potential)
Ex: K+, Na+, Cl-, Ca++
Facilitated Diffusion - Channel Mediated - Voltage Gated
