During digestion, the presence of proteases makes proteins be digested first. Given this occurrence, what is the catalytic rc of the proteases? (Reference: https://www.britannica.com/science/proteolytic-enzyme) It does not do anything directly to the digestion process of proteins It boosts the digestion process to match the digestion of all food matter It slows down the digestion process of other food matter It speeds up the digestion of proteins ingested by the organism 0000
Which of the following best describe protein digestion? . Protein digestion is a hydrolytic process regulated by pH changes in the gastro-intestinal track, and hormonal and enzyme releases at various stages of digestion. .. Protein digestion occurs during the gastric phase of digestion starting in the stomach. Protein digestion cleaves peptide bonds releasing peptides, and amino acids Protein digestion is a hydrolytic process involving proteases/ proteinases Protein digestion occurs at the active site of proteases and is effected by the catalytic triads.
Arrange (1-15) the following statements based on their order from lipogenesis, lipolysis, beta-oxidation to ketogenesis. Acetoacetic acid is converted to β-hydroxybutyric acid and acetone Acetyl CoA is transported with oxaloacetate to the cytosol as citrate Palmitic acid is separated from the complex Creation of carbonyl group in the β-carbon Fuelling the different tissues, ketone bodies are transported to the blood Glyceraldehyde-3-PO4 is produced from the conversion of glycerol Unsaturation of the α & β-carbons of the FA chain Acetyl CoA is converted to acetoacetic acid Acetyl CoA and oxaloacetate are produced from citrate Hydolysis of the double bond in the FA acid chain Malonyl CoA is produced from CO2 fixation of acetyl CoA Acetyl CoA enters the Krebs Cycle Separation of the two-carbon product from the fatty acyl CoA Malonyl CoA is converted to saturated FA complexed with protein TG is hydrolyzed to FA and glycerol
Lipogenesis, or fatty acid synthesis, occurs in several cycles. A diagram of the reactions of the first cycle of fatty acid synthesis is shown. Select all of the true statements. Malonyl-CoA adds a two-carbon group to the growing fatty acid chain with each cycle. Acetyl-SCOA provides the carbon used for fatty acid synthesis. The reactions of lipogenesis include, but are not limited to, condensation, reduction, and dehydration. The first cycle of lipogenesis yields CO₂, one NADP+, and an acyl group attached to ACP. In lipogenesis, acetyl and acyl molecules are activated by an acyl carrier protein (ACP). Each cycle lengthens the fatty acid chain by three carbon atoms. _i CH3-C-S-KS+ 0-C-CH₂-C-SACP acetyl-ACP malonyl-ACP CO2 || CH3 C-CH₂-C-SACP NADPH + H+ NADP+ OH || CH3 CH-CH₂-C-SACP H₂O || CH3CH=CH-C-SACP NADPH + H+ NADP+ CH3CH₂CH2-C-SACP
