Photosynthesis 6CO 2 +6H 2 0+ energy  6O 2 + C 6 H 12 O 6 Respiration 6O 2 + C 6 H 12 O 6  6CO 2 +6H 2 0+ energy

Chemical process, combining & splitting of molecules

Assembly of complex molecules from simple molecules is a process

Breakdown of large molecules into smaller molecules Breakdown of carbohydrates manufactured during photosynthesis to release ATP

Breakdown of glucose, requiring oxygen Takes place in the Mitochondria

 Chemical energy is released when the molecular bonds of the sugar molecules are broken.  ATP drives a variety of growth and development of the plant  By product reaction are CO 2 and Water

 Less efficient form of respiration  Does not require oxygen  Used in soil and water where oxygen is in short supply

 Some bacteria and fungi adapted to anaerobic respiration covert energy by fermentation  Produces ethyl alcohol and lactic acid  Human recognized the value of fermentation in the making of silage, beer, and wine.

 Plant growth takes place primarily at night when photosynthesis is shut down.  Fueled by aerobic respiration.

1. Glycolysis 2. Acetyl CoA 3. Citric Acid cycle (Kreb’s Cycle) 4. Electron transport chain

 Glycolysis  Acetyl Coenzyme A  Citric Acid Cycle - through the first 3 steps, hydrogen atoms were transferred to hydrogen acceptors NAD and FAD, forming NADH and FADH2

 Aerobic respiration, these reduced compounds enter the electron transport system

 Series of chemical reactions by which electrons are passed from one acceptor molecule to another.  Oxygen is the final hydrogen acceptor.  During this pathway, ATP is synthesized by the process of chemiosmosis.

The process in which hydrogen atoms cross the thylakoid membrane and travel down a protein gradient, producing ATP, This 4 th stage see the production of 32 ATP molecules. What is also made and released (Transpiration)
