2. Respiration
Energy: Ability To do work is called Energy.
Law of thermodynamics in Biological system
All biological organisms require energy to
survive. In a closed system, such as the
universe, this energy is not consumed but
transformed from one form to another.

3. Cells, for example, perform a number
of important processes. These
processes require energy. And these
energy come from respiration.
Respiration: Glucose breakdown in the
presence of oxygen to form carbon
dioxide and water with the release of
energy. respiration
 6C6H1206+ 6O2 respiration 6CO2+ 6H20+ energy

4. Energy released is coupled to the
synthesis of ATP.
ATP is essential for plant cell
maintenance, growth and development.
Carbohydrate Conversion
Starch glucose
Sucrose + water glucose + fructose

5. Respiration in Leaves.

6. Stages of respiration
 1) Glycolysis
 2) Kreb’s Cycle
 3) Electron transport chain

7. Glycolysis:
 Glycolysis is occurs in the cytoplasm of
cells, outside of mitochondria.
 Glycolysis is requires glucose and 2 ATP to
split the glucose molecule, 2 NAD+ that
will become electron carrier molecules,
and 4 ADP + P that will become 4 ATP.

9. TCA Cycle

11. Kreb’s Cycle;
 mitochondrial matrix
only if oxygen present
converts pyruvate via acetyl CoA into
CO2; generates NADH and FADH2

12. Electron transport hain:
mitochondrial membranes = cristae
transfers electrons from NADH and FADH2
to reduce O2 to H2O and generate ATP.

14. Types of Respiration:
Aerobic respiration
Anerobic respiration

15. Aerobic Respiration
 Aerobic respiration
take place in
presence of oxygen.
 Aerobic respiration
occurs in most
cells.
 Combustion:
complete.
Anerobic Respiration
 Anerobic
respiration take
place without
oxygen.
 Anaerobic
respiration occurs
mostly in
prokaryotes.
 Incomplete.

16.  Stages:
Glycolysis, Krebs cycle,
Electron Transport
Chain.
 Site of reaction:
Cytoplasm and
mitochondria.
 Amount of energy:
High (36-38 ATP
molecules).
 Stages:
Glycolysis, Krebs cycle,
Electron Transport
Chain.
 Site of reaction:
Cytoplasm and
mitochondria.
 Amount of energy:
Lower (Between 36-2
ATP molecules).
