macromolecules (general)

Question 1

answering technique for describing how bond between monomers is formed

Answer 1

• name of bond
  
  • e.g. B (1,4) glycosidic bond, phosphodiester bond
• formed between … of one monomer and … of another monomer
  
  • e.g. bet C1 of 1 glucose monomer and C4 of another glucose monomer, bet 5’-P grp of 1 nucleotide and 3’-OH grp of another nucleotide
• condensation reaction joining the 2 monomers tgt with removal of one water molecule
• reaction is catalysed by enzymes
  
  • be specific if it’s a known enzyme

Question 2

reasons cellulose is synthesised at cell surface membrane and not inside cell

Answer 2

• cellulose molecule may be too large to pass through cell membrane
• cellulose is insoluble in hydrophobic core of phospholipid,
  and thus cannot pass through it
• cellulose is a macromolecule found outside cell as part of the cell wall,
  and thus it’s easier to synthesis at cell surface membrane and then simply deposit it at cell wall
