About This Presentation

it's about the respiration in plants and also types of respiration include with stages of respiration.


Slide Content

  Name Muneeb ur rehman Class No 651 Department Agronomy Presentation Reespiration in plants

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. 

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 6C 6 H 12 6 + 6O 2 respiration 6CO 2 + 6H 2 0+ energy

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

Respiration in Leaves.

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

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.

Glycolysis Glucose (6C) 2 Pyruvate (3C) -O 2 -O 2 CO 2 +O 2 Ethanol Lactate TCA Cycle

TCA Cycle

Kreb’s Cycle; mitochondrial matrix only if oxygen present converts pyruvate via acetyl CoA into CO 2 ; generates NADH and FADH 2

Electron transport hain: mitochondrial membranes = cristae transfers electrons from NADH and FADH 2 to reduce O 2 to H 2 O and generate ATP.

Electron transport System NADH and FADH 2 e - e - H + H + ATP 4e - + 4H + + O 2 2H 2 O cyt . oxidase

Types of Respiration: Aerobic respiration Anerobic respiration

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.

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).
