What does haemoglobin bind with?
Oxygen.
What do iron ions in haemoglobin transport?
Oxygen.
What does haemoglobin associate with?
Oxygen.
What is the role of iron ions in haemoglobin?
Haemoglobin binds/associates with oxygen.
What do sodium ions help co-transport into cells?
Glucose and amino acids.
What is co-transported with glucose and amino acids into cells?
Sodium ions.
What pump moves sodium out of cells?
Na–K pump / sodium-potassium pump.
What type of transport moves sodium out of cells?
Active transport.
What does sodium active transport create?
A sodium concentration/diffusion gradient.
What gradient is created by the movement of sodium ions?
Sodium concentration/diffusion gradient.
What do sodium ions affect in relation to water movement?
Osmosis / water potential.
What do phosphate ions affect (in terms of water)?
Osmosis / water potential.
What do phosphate ions join together?
Nucleotides.
What kind of bond do phosphate ions form in DNA/RNA?
Phosphodiester bond.
What part of DNA/RNA do phosphate ions form?
Backbone.
Where are phosphate ions found in nucleic acids?
In the backbone of DNA/RNA/in nucleotides.
What do phosphate ions help produce?
ATP.
What compound do phosphate ions phosphorylate?
Other compounds (usually) making them more reactive.
What effect does phosphorylation by phosphate ions have?
Makes compounds more reactive.
What part of the phospholipid bilayer are phosphate ions involved in?
Hydrophilic/water-soluble part.
What part of a membrane are phosphate ions part of?
Phospholipid bilayer.
