Question

An animal cell is missing an enzyme that attaches sugar molecules to membrane proteins.

What will be the consequences? (1)​

Answer 1

Answer:

Enzymes in the membrane can do the same thing they do in the cytoplasm of a cell: transform a molecule into another form. Anchor proteins can physically link intracellular structures with extracellular structures.

biological properties of a protein molecule depend on its physical interaction with other molecules. antibodies attach to viruses or bacteria to mark them for destruction, the enzyme hexokinase binds glucose and ATP so as to catalyze a reaction between them, actin molecules bind to each other to assemble into actin filaments, and so on. Indeed, all proteins stick, or bind, to other molecules.
