peripheral, extrinsic

Question 18

surface bound monotopic

Answer 18

integral, intrinsic

Question 19

transmembrane bi- and polytopic

Answer 19

integral, intrinsic

Question 20

gap junctions

Answer 20

create channels between cells. these channels enable ions and small molecules to pass through the membrane via passive diffusion.

Question 21

integrins

Answer 21

transmembrane receptor proteins that link the extracellular membrane to the cytoskeleton inside of the cell

Question 22

How many functional membrane bound compartments does a chloroplast have and what are they?

Answer 22

3
- Inter membrane space, stroma, and thylakoid lumen

Question 23

what is the inter membrane space of a chloroplast

Answer 23

where the inner and outer membrane are

Question 24

what is the stroma of the chloroplast

Answer 24

fluid filled inside the inner membrane

Question 25

what is the thylakoid lumen of the chloroplast?

Answer 25

space inside the thylakoid membranes

Question 26

endocytosis

Answer 26

The endocytic pathway allows cells to engulf extracellular material via vesicles that fuse with lysosomes for digestion and recycling of biomolecules.
