Biology Molecule
Unit 1
-man is high 50’s to 60% water
-distribution in body divided into 3 compartments:
1) intracellular - 28 litres
2) intercellular/interstitial fluid - 11 litres - 80%
3) blood plasma - 3 litres - 20%
-women contain less water than men
-organisms can contain 60-80% water
-bacteria have lots of water
-fat cells have little
-water’s properties result from its structure and molecular interactions
-water is polar
-polar covalent bonds and asymmetrical shape give it opposite charges on
opposite sides
-electrons spend more time around O giving H …showed first 75 words of 2247 total…

-ATP molecules usually last less than a minute before being broken down
-~40 kg is produced in a day
-if a cell needs energy, it hydrolyses ATP and releases energy in small
packets
NAD:
-contains ribose sugar, adenine and 2 nucleotides
-one nucleotide does not contain any of the 5 bases, but instead a
nicotinamide ring
-they can accept hydrogens and become NADH
-hydrogens are accepted or passed on during respiration or photosynthesis
