1. In sickle cell anemia has a...

  • lot of biconcave red blood cells.
  • noncharged polar amino acid that has been replaced by polar molecule one. This alters hemoglobin leading to decreased oxygen carrying capacity and cell deformation.
  • charged, polar amino acid that has been replaced by a non-polar one. This alters hemoglobin leading to decreased oxygen carrying capacity and cell deformation.
  • a lot of hemoglobin in cells.
