Cards in this deck (8)
- 1Affinity for oxygenHaemoglobin (Hb) with a high affinity takes up oxygen easily and releases it less readily.
Hb with a low affinity takes up oxygen less easily but releases it more rapidly - 2AssociatingThe process by which Hb combines with oxygen (in the lungs)
- 3DissociatingThe process by which Hb releases oxygen (into the tissues)
- 4Oxygen Dissociation curveThe s-shaped curve shown by how Hb binds oxygen (first molecule is hard to load, next three load easily
- 5StarchStorage molecule in plants, it is coiled, insoluble and can be hydrolysed to form α-glucose
- 6GlycogenStorage molecule in animals, which has short chains so it can be readily hydrolysed to α-glucose
- 7CelluloseParallel chains of β-glucose joined by hydrogen bonds, forms myofibrils for strength
- 8ChloroplastsOrganelle in plant cells containing grana, thylakoids and stroma. Photosynthesis occurs here.
