- Identify the original site of these chemical secretions- these should be labeled on the diagram: Pepsin HCL (hydrochloric acid) Sucrase Lactase Maltase Bile Salivary amylase Pancreatic lipase Pancreatic amylase Aminopeptidase Sodium Bicarbonate Trypsin Carboxypeptidase Insulin GlucagonGlucose is reduced by Bromine water (Br2/H20) to gluconic acid Nitric acid (HNO3) to glucaric Enzymes to glucuronic acid NaBH4 to sorbitolLipogenesis, 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

Exclusion of milk from the diet did not give a positive result. After feeding with sucrose, the level of glucose in the blood barely increased. Why could such symptoms occur? hereditary lactase deficiency hereditary insufficiency of sucrase disorders of transporters secondary lactase deficiency deficiency of amylaseDefine lipase
- containing Compared to the glucose-sweetened beverages, beverages caused significant increases in belly fat, fatty liver, and never cause satiety. This is learnt from the course materials. O galactose Ocellulose fructose lactose insulin"The following describe lipoprotein organization, classification & function, EXCEPT: " Each type of lipoprotein has a characteristic apoprotein necessary for the transport and metabolism of the lipid inside "Lipid content is less than protein thus, the higher the % TAG the less dense the lipoprotein" The amount of cholesterol and cholesteryl ester increases as lipoprotein density decreases "Chylomicrons and VLDL transport dietary and biosynthesized lipids to the peripheral tissues, respectively"Most amino acids are degraded in the liver. This is not trueof the branched-chain amino acids, most of which are degraded in extrahepatic tissues with high protein turnover.Suggest some examples of these tissues.
