Here's a taster:

Aerobic Respiration
2 X ATP Glycolysis
made overall Takes place in Cytoplasm
2 molecules of ATP
needed for reaction Glycogen 6C
to take place (number of carbons in
the molecule)
2 ATP 2 ADP + Pi
2 X Triose Phosphate 3C
O
X
NAD I When oxidation
Get two molecules of R ED
UC D
reaction takes place,
triose phosphate and A
4 ATP
TI
O T reduction reaction
pyruvate
N

NADH2 O
N
also takes place and
vise versa (called a
2 X Pyruvate 3C redox reaction)…read more

Here's a taster:

Aerobic Respiration
No ATP Link Reaction
made Takes place in matrix of
mitochondria
Pyruvate travels from 2 X Pyruvate 3C
cytoplasm to matrix of O CO2 lost so acetyl
X
mitochondria only has 2 carbons
NAD R ED

NADH2 O
N
Coenzyme transports
acetyl to Krebs cycle Acetyl 2C
then is recycled back
to link reaction
Coenzyme A
Aceytl Coenzyme A 2C…read more

Here's a taster:

Aerobic Respiration
4 X ATP Krebs Cycle Takes place in matrix of
made overall mitochondria
Coenzyme A is Aceytl Coenzyme A 2C
recycled back to link
reaction
4C
Acetyl coenzyme
A joins with a 4C
CO2 lost so molecule molecule, making
now only has 4 6C
a 6C molecule as
carbons which it enters the Krebs
travels back round cycle

Here's a taster:

Aerobic Respiration
Electron
32 X ATP Transport Chain (Oxidative Phosphorolation)
made overall
MATRIX e- travels down energy levels, as it travels Takes place in
energy is released which is used to actively LOW cristae of
transport H+ through membrane
INNER mitochondria
MEMBRANE H+ Active Transport because going from low
concentration of H+ in Matrix to high
concentration of H+ in Inter membrane space
NADH2 and H+
FADH2 from Krebs e- O2 at end of energy levels pulls
cycle are split into e- H+ electrons down energy levels H 2O
electrons and H+ and accepts them (so is known
as Terminal Electron Acceptor) O2 and e-
protons
join with
H+ to make
H2O

Anaerobic Respiration
2 X ATP In Animals
made overall Takes place in Cytoplasm
6C Glycogen
Its the same as
2 ATP 2 ADP + Pi glycolysis but with a
