hydrophobic areas
2) contains ___________ and integral proteins
●● facilitated diffusion
Answer: movement of particles down their concentration gradient
(diffusion) with the help of carrier proteins
●● active transport
Answer: movement of particles against their concentration gradient with
the help of carrier proteins
●● endoplasmic reticulum
Answer: 1) attachment sites for ribosomes
2) involved in protein and membrane synthesis,
3) formation of vesicles for transport. Exclusive to eukaryotes.
