only occure in animal to organize their Microtubles

40
Q

Centromere

A

found in near the nucleus but the migrate to opposite poles cells during cell divison

41
Q

Polar fibers

A

extend from one centromere to the other while kinetichore fibres attache to chromosomes, pulling sister chromatids during anapahse

42
Q

Plasma Membrane is involved in

A

Function such as regulation and transportstion of materials - cell signaling and cell to cell recognition

43
Q

Amphipathic

A

Phospholipids and they have both hydrophilic and hydrophobic components

44
Q

Phospholipids

A

Consist of two nonpolar fatty acid chain bonded to a polar head made of glycerol

45
Q

Micelle

A

Is a small spherical structure made of singular phospholipids and tails pointed N-word to form hydrophobic core

46
Q

Protein component - C.J.C.C

A

Shutting various ions and molecules through membrane

Catlyzing reactions
joining adjacent cells
cell signaling
cell support and stability and cell recognition

47
Q

Glycoproteins
