Drag labels to the appropriate locations in this diagram.
Vinil7 [7]

Answer:

c = Enzymatic activity

e = Attachment to ECM and cytoskeleton

f = Signal reception and relay

g = Transport

h = Intercellular junctions

i = Cell-cell recognition

a = Phospholipid bilayer

b = Fibers of extracellular matrix (ECM)

d = Microfilaments of cytoskeletons

Explanation:

c) Enzymatic activity is an indication of the amount of active enzymes present to increase a reaction rate

e) Attachment to ECM and cytoskeleton is enabled by integrins that take signals from the ECM and control signaling pathways of the cell

f) Signal reception and relay is the transduction of signal

g) Transport is the movement of matter in and out of the cell through the cell membrane

h) Intercellular junctions are the contact regions between adjacent cells and plasma membrane

i) Cell-cell recognition is power of the cell to decipher the different neighboring cells in the cell's environment

a) Phospholipid bilayer consists of a hydrophobic interior and a hydrophilic exterior

b) Fibers of extracellular matrix (ECM) are ECM associated the cell

d) Microfilaments of cytoskeletons consist of actin and aid in cellular movement.

Attached is the image respective of the question. 

First, both the extracellular fluid and the cytoplasm are hydrophilic. The phosphate head of the phospholipid is hydrophilic hence it either faces the extracellular fluid and the cytoplasm. The lipid tail of the phospholipid is hydrophobic hence it is confined in the middle of the plasma membrane. Both cytoplasmic and the extracellular fluid ends of the transmembrane protein are hydrophilic and the middle part of the transmembrane protein is hydrophobic.
