Here's a taster:

IN Glucose , x1 ATP
2
-Gluose is a hexose sugar
which needs to split up)
-So one molecule of ATP is
Stage 1A: hydrolysed, releasing a
phosphate group and this is
Phosphorylation attached to the glucose. This
is called Glucose-6-phosphate
Glucose- 6- Phosphate OUT…read more

Here's a taster:

p IN Glucose x1 ATP 3
-Then, Glucose- 6 is changed
to fructose-6 phosphate
since both of them are
isomers
-Another ATP is hydrolysed Stage 1B:
so that the released
phosphate group is attaches
to the fructose-6 Phosphate
Phosphorylation
-Energy from the hydrolysed
ATP molecule activates
hexose sugar, preventing it
from being transported out
of the sugar
-The activated sugar is
hexose 1,6 diphosphate OUT
Hexose -1,6 diphosphate…read more

Here's a taster:

ADP NAD 5
IN
Triose
ADP NAD
Triose
-The triose
phosphate is
oxidised since two
H-atoms are
removed from each
Stage 3A: production
triose-phosphate
with the help of of ATP
enzyme
dehydrogenze and
aided with NAD
(hydrogen acceptor)
-Two of the ADP are ATP NADH
phosphorylated,
producing two ATP OUT
ATP NADH…read more

Here's a taster:

ADP NAD 6
IN Triose
-A number of micro Triose ADP NAD
reactions occur,
catalysed by enzymes
convert each triose
phosphate into
pyruvate molecule. Stage 3B:
production of ATP
OUT
ATP ATP NADH Pyruvate
ATP ATP
