Plants use cellular respiration as a means to convert stored energy into a chemical that cells can consume.


Chemically, in cellular respiration glucose molecules are broken down to create ATP , expelling water and carbon dioxide as by products.
Cellular respiration involves 4 steps
A) Glycolysis:
glucose molecules are broken down to pyruvic acid

B) Kreb's cycle:
Pyruvic acid is broken down to release energy. This
energy is used in the formation of high energy
compounds like NADPH

C) Electron transport system :
Electrons are transported along a series of co - enzymes
and cytochromes which in turn releases their energy

D) Chemiosmosis :
Here the energy given off by the electrons is used to
pump protons across a membrane and provide energy
for ATP synthesis.

Glycolysis occurs in the cytoplasm
Kreb's cycle, Electron transport system and Chemiosmosis occur in the mitochondria.
