Enzymes that digest dietary proteins in the stomach and intestine are synthesized as proenzymes or zymogens. Which of the following is the proenzyme form of a proteolytic enzyme of the digestive tract? elastase O carboxypeptidase chymotrypsin
based on where they perform their functions the enzymes amylase and maltase in human saliva are classifies as________.
Pepsin and pancreatic digestive enzymes are regulated by: Allosteric regulation Zymogen activation Covalent modification Competitive inhibition
Refer to the statements below: 1. An amino acid is considered glucogenic if it has a carbon-containing degradation product that can be used to produce glucose via glycolysis 2. An amino acid is considered ketogenic if it has a carbon-containing degradation product that can be used to produce ketone bodies 3. Amino acids can be both glucogenic and ketogenic None of the statements are correct Only one of the three statements is correct Only two of the three statements are correct All three statements are correct
Consider the reactions of ketogenesis. (a) What role does acetyl-CoA play?(b) How many acetyl-CoA molecules are used in the production of the ketonebodies?(c) What is the essential role of ketone bodies during prolonged starvation?
Which of the following monosaccharide phosphates is NOT produced in the pentose phosphate pathway? O seduheptulose-7-phosphate O mannose-6-phosphate O ribose-5-phosphate O erythrose-4-phosphate
Is human salivary alpha amylase under covalent modification.?
The cells that line the mammalian intestine produce glycoproteins with O-linked oligosaccharides. Some of the glycoproteins remain anchored to the cell surface and some are released into the intestinal space. In a healthy animal, numerous microbial species (the microbiome) live in the intestine. These organisms produce fucosidase, an enzyme that hydrolyzes glycosidic bonds involving fucose. (a) Why is this enzyme useful to the micro organisms? (b) Pathogenic (disease-causing) bacteria typically lack fucosidase. How does this help prevent the growth of pathogens in the intestine, particularly during an illness when the human host stops eating?
How does the presence of a-bonds versus B-bonds influence the digestibility of glucose polymers by humans?Hint: There are two effects.
Which of the following most accurately describes the impact acetyl-CoA has in the cytosol of the liver cell? Acetyl CoA serves as an allosteric inhibitor of PFK Acetyl CoA serves as an allosteric inhibitor of pyruvate kinase Acetyl CoA serves as an allosteric activator of PFK Acetyl CoA serves as an allosteric activator of pyruvate kinase Acetyl CoA serves as an allosteric activator of fructose-2,6-bisphosphatase Acetyl CoA serves as an allosteric activator of PFK-2
Enumerate the different enzymes involved in the following lipid metabolic pathways. Show schematically the role of each using relevant reactions that they catalyze. Do not forget to label your substrates and products properly. You may illustrate and/or explain elaborately if necessary. 1. beta-oxidation 2. lipogenesis (towards 1 molecule of triacylglycerol)
All of the following statements about glucose are true except: Glucose is metabolized in the cytoplasm of prokaryotic organisms. On a low-carb diet, keto acids from glucogenic amino acids will be used to synthesize glucose. Glucose is metabolized in the mitochondria of mature red blood cells. Under non-starvation conditions, the brain relies exclusively on glucose as its fuel source.
