This Concept Map, created with IHMC CmapTools, has information related to: 15.2 AEROBIC RESPIRATION, *Two rounds of the citric acid cycle are needed to process the two molecules of acetyl-CoA formed from the original glucose molecule.The hydrogen atoms removed are used to form six NADH and two FADH2,both of which are used later.Also,a small amount of ATP is produced. ???? *In glycolysis and Krebs cycle,a few ATP were produced directly through substrate-level-phosphorylation.In synthesis of ATP via substrate-level-phosphorylation, an enzyme transfers a phosphate from one substrate molecule to ADP,producing ATP.Chemiosmosis and ATP synthase are not involved, and the phosphorylation can occur with or without oxygen., *After glycolysis occurs,pyruvates enter the mitochondria and diffuse to the matrix.Once inside the mitochondhria's matrix,a pyruvate is converted by the enzyme pyruvate dehydrogenase to acetyl-CoA(acetyl coenzyme A).The coenzyme can then enter the Krebs cycle. ???? *Krebs cycle occurs in matrix of mitochondria.Here,the remaining hydrogen atoms and their energy rich electrons are removed.The Krebs cycle is also known as citric acid cycle., *When electrons are transferred from one carrier to the next carrier via the electron transport chain,they are coupled to ATP synthase enzyme complex for the production of ATP from ADP and inorganic phosphate(Pi).The whole process, where oxygen effectively allows the production of ATP by phosphorylation of ADP,is called oxidative phosphorylation. ???? *Oxidative phosphorylation is quite similar to photophosphorylation since it involves an electron transport chain,chemiosmosis,ATP synthase and oxygen.However,oxidative phosphorylation uses energy from NADH to stimulate the electron flow for chemiosmosis synthesis of ATP rather than light energy.The process is called oxidative phosphorylation because it begins with oxidation,which means the loss of electrons., 15.2:AEROBIC RESPIRATION involves Formation of acetyl A/Link reaction, *In glycolysis and Krebs cycle,a few ATP were produced directly through substrate-level-phosphorylation.In synthesis of ATP via substrate-level-phosphorylation, an enzyme transfers a phosphate from one substrate molecule to ADP,producing ATP.Chemiosmosis and ATP synthase are not involved, and the phosphorylation can occur with or without oxygen. ???? *The FADH2 and NADH proceed to the cristae where they provide energy for the electron transport chain.In the electron transport chain,these NADH and FADH2 molecules are transferred along a series of acceptors., 15.2:AEROBIC RESPIRATION involves Glycolysis, 15.2:AEROBIC RESPIRATION involves Krebs cycle, *Glycolysis takes place in the cytoplasm.During glycolysis,each molecule of glucose is broken into two three-carbon molecules of pyruvate.Some of the electrons (as part of hydrogen atoms) obtained from the original glucose molecule are used to reduce two molecules of NAD+,forming two NADH;these NADH molecules are used later in aerobic respiration. ???? *After glycolysis occurs,pyruvates enter the mitochondria and diffuse to the matrix.Once inside the mitochondhria's matrix,a pyruvate is converted by the enzyme pyruvate dehydrogenase to acetyl-CoA(acetyl coenzyme A).The coenzyme can then enter the Krebs cycle., 15.2:AEROBIC RESPIRATION involve Oxidative phosphorylation which consist of electron transport chain and chemiosmosis, *Krebs cycle occurs in matrix of mitochondria.Here,the remaining hydrogen atoms and their energy rich electrons are removed.The Krebs cycle is also known as citric acid cycle. ???? *Two rounds of the citric acid cycle are needed to process the two molecules of acetyl-CoA formed from the original glucose molecule.The hydrogen atoms removed are used to form six NADH and two FADH2,both of which are used later.Also,a small amount of ATP is produced., *The FADH2 and NADH proceed to the cristae where they provide energy for the electron transport chain.In the electron transport chain,these NADH and FADH2 molecules are transferred along a series of acceptors. ???? *When electrons are transferred from one carrier to the next carrier via the electron transport chain,they are coupled to ATP synthase enzyme complex for the production of ATP from ADP and inorganic phosphate(Pi).The whole process, where oxygen effectively allows the production of ATP by phosphorylation of ADP,is called oxidative phosphorylation.
