metabolism
metabolism
all chemical reaction in the body
living things need to be making new molecules for growth or replace old cells
the raw materials for molecules in in the food that we eat (digestion)
not how much food you can eat of how fast it can break down.
metabolism is the sum of all the reactions happening in a cell or an organism, in which molecules are made or broken down
the 5 reactions in metabolism
the conversion of glucose to starch, glycogen and cellulose
making lipids
making proteins
respiration
in plants, glucose and nitrates used to make proteins
formation of molecules
glucose
glycogen in animals
starch or cellulose in plants
lipids
storage of fat and oils
used as long term energy storage and insulation
(fats)
proteins
amino acids are joined to make new proteins
used for growth and repair
urea
breakdown of excess amino acids
broken down in the liver
kidneys remove urea
respiration
glucose is oxidised into carbon dixoide and water
energy is released
