VACUOLE

Filled with cell sap to keep cell turgid ( enlarged
and swollen with water)



ENZYMES

Are biological catalyst made up of proteins

Enzymes don't directly take part in a reaction and
remained unchanged at the end. They have an
optimum temperature of 37 degrees and once they get
hotter…

Anaerobic respiration is when glucose breaks down
into a substance called lactic acid and some energy is
release

GLUCOSE LACTIC ACID + ENERGY



OXYGEN DEBT

Lactic acid builds up in the tissues due to anaerobic
respiration it is repaid by oxidising the lactic acid into
glycogen.
