also called the Tricarboxylic Acid Cycle (TCA Cycle) or the CITRIC ACID CYCLE • an aerobic process which takes place in the mitochondria • oxidizes / breaks down the PYRUVATE formed after glycolysis • the pyruvic acid (3-C) is first decarboxylated and forms the ACETYL CoA (Acetyl coenzyme A). This occurs in the mitochondria. It is the Acetyl CoA that enters the Krebs Cycle

A_______ C___ is the connecting link between glycolysis and the Krebs Cycle
Acetyl CoA

combines with oxaloacetate (4-C), to form a 6-carbon compound, CITRIC ACID
Acetyl CoA

• a series of oxidation-reduction reactions which move electrons to several protein carriers in or on the mitochondrial membrane • a sequence of electron carriers that use the energy from electron flow to transport protons against a concentration gradient across the inner mitochondrial membrane • involves the transfer of electrons from NADH and FADH2 to oxygen with the accompanying conversion of energy to ATP
Electron transport system

Occurs in mitochondria and cytoplasm Releases carbon dioxide and water Utilizes oxygen (aerobic respiration Chemical energy is transformed into kinetic energy Releases energy from sugar molecules Occurs in either light or darkness Decreases dry weight Produces ATP with energy released from sugar
Respiration
217
Occurs in chloroplasts Uses carbon dioxide and water Produces oxygen in green organisms Kinetic energy of light is transformed to chemical energy Stores energy in sugar molecules Occurs in light only Increases dry weight Produces ATP with light energy
