■ The complete oxidation of one glucose molecule produces the following ATP molecules in each step. • Glycolysis; • Formation of acetyl CoA; • Krebs cycle; • Electron transport chain. ■ In addition, glucose catabolism produces six CO2 molecules and water.

• During digestion, complex carbohydrates are hydrolyzed into monosaccharides, primarily glucose. • The catabolism of glucose is the primary source of energy for cellular production of ATP. • The anabolism of glucose is important in regulating blood glucose levels. • Glucose cat...
Protein catabolism - deamination
By: HWC, Views: 7879
• Digestion hydrolyzes proteins into amino acids, which are transported to the bloodstream. • Amino acids and proteins are not stored. • Instead, they are: • Oxidized to generate ATP. • Used to synthesize new proteins. • Converted to carbohydrates or lipids for storage (if e...
Lipid catabolism - lipolysis and beta oxidation and oxidation of fatty acids
By: HWC, Views: 7962
• Digestion hydrolyzes lipids into fatty acids and glycerol. • Fatty acids and glycerol are: • Oxidized to generate ATP. • Used to produce triglycerides that are stored as energy reserves in adipose tissue. • Lipid catabolism begins with lipolysis in which lipids are broken do...
Protein catabolism (Krebs cycle) and Protein anabolism (protein synthesis)
By: HWC, Views: 8169
• Deaminated acids are brought into the Krebs cycle to be oxidized to CO2 and H2O. • Before entering the Krebs cycle, the deaminated acids are converted into intermediate products (pyruvic acid, acetyl coenzyme A, carbonic acids). • In the Krebs cycle, amino acids are oxidized to form r...
Types of energy transfer reactions: oxidation-reduction reactions and ATP generation reactions
By: HWC, Views: 8261
■ Metabolism balances anabolic and catabolic reactions. ■ Anabolism is energy transfer from ATP to simpler molecules in order to build them up into larger, more complex molecules. ■ Catabolism is breaking down larger, more complex molecules, usually to transfer energy from them in order...
Cortisol (protein catabolism, gluconeogenesis, vasoconstriction & anti-inflammation)
By: HWC, Views: 7300
• Stressors stimulate production of hypothalamic releasing hormones, corticotropin releasing hormone, hormone (CRH) and adrenocorticotropic hormone (ACTH) stimulate. • These hormones promote increased production of 1 cortisol from the zona fasciculata cells of the adrenal cortex. • Cort...
Lipid catabolism ( ketogenesis and oxidation of glycerol) and Lipid anabolism (lipogenesis)
By: HWC, Views: 8029
• During excessive beta oxidation, the two-carbon fatty acid fragments are converted into acidic ketone bodies. • Ketosis, the overproduction of ketone bodies, can lead to acidosis (ketoacidosis) of the blood. • After lipolysis, glycerol is converted to pyruvic acid. • Pyruvic aci...

Glycogenolysis and lipolysis • Stressors stimulate production of a hypothalamic releasing hormone (GHRH). • The releasing hormone stimulates somatotroph cells of anterior pituitary to secrete human growth hormone. • Human growth hormone targets liver cells and fat cells. hGH (glycog...
