2.2 Water/Metabolism Flashcards
What is metabolism?
a chemical processes that happens within a living organism in order to maintain life. It is the web of all the enzyme-catalysed reactions in a cell.
What is anabolism?
Synthesis of complex molecules from simpler ones. when smaller molecules make bigger ones.
What is catabolism?
Breakdown of complex molecules into simpler ones. Big ones go into smaller ones.
How do water molecules have dipolarity?
because they are dipoles meaning they have two poles.
What is the specific heat capacity of water?
4.2 j/g/c
What is the latent heat of vapertization of water?
2257 j/g
How does NaCl get transported?
it is soluble in water and is then transported as Na+ and Cl- ions
How does glucose and amino acids get transported?
they are polar so dissolve into plasma membrane and are then transported.
How does oxygen get transported?
since it is not polar it needs haemoglobin to bind with.
How does cholesterol get transported?
it is not polar so is transported in small droplets called lipoproteins.
What is a condensation reaction?
Where two molecules join to form a larger one + water.
What is a sub unit of a condensation reaction called?
Monomer?
What are two monomers joined together called?
dimer
When lots of monomers are joined together?
polymer
What are monosaccharides?
They are sub units for carbohydrates
