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 CO2 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. Glycolysis2. Acetyl CoA3. 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 4th stage see the production of 32 ATP molecules. What is also made and released (Transpiration)
