Switchgrass is used for ethanol production. The composition of the switchgrass is 37% cellulose, 24% xylan, 3% galactan, 4% arabinan, 20% lignin, 7% extractives, and 5% ash. A dilute acid pretreatment method is applied to the switchgrass before enzymatic hydrolysis and fermentation. The pretreatment hydrolyzes 10% hexosan and 90% pentosan into monomeric sugars. Approximately 30% of the hydrolyzed pentoses further react & are decomposed to furfural. Assume that there is no decomposition of the hydrolyzed hexoses. Further Assume that lignin, extractives, and ash do not change during the pretreatment. • How much of each lignocellulosic sugar (glucose, xylose, galactose, and arabinose) is produced when pretreating 1,000 kg (dry matter) switchgrass? How much furfural is formed? • Is water consumed or produced in these pretreatment hydrolysis and dehydration reactions? How much in each?

I'm using DNS reagent to test starch digestibility and find that MOCAF (modified cassava flour) has higher starch digestibilty compared to native cassava flour? i think it should be lower because MOCAF undergoes fermentation. can someone help me to explain why mocaf has higher than native cassava?.

PLEASE HELP ME ANSWER THE TABLE THANK YOU ALCOHOLIC FERMENTATION IntroductionThe conversion of carbohydrate such as sugar into an acid or alcohol is calledfermentation. Fermentation that uses yeast is termed as alcoholic fermentation.Glucose -------- carbon dioxide and alcohol + energyThe enzyme in yeast catalyzes alcoholic fermentation which actually occurs as a two-step process. This process takes place under anaerobic conditions such as in the absence ofoxygen liberating a small amount of energy. Some carbohydrates are not hydrolyzed tosimple sugars by yeast under anaerobic conditions due to the lack of the specific enzymesneeded to catalyze the reaction. Fermentation of simple sugars by yeast has different rates ofreaction.1. The first step involves the decarboxylation of pyruvate from glycolysis toacetaldehyde acted by the enzyme pyruvate decarboxylase.2. The second step is the reduction of acetaldehyde which is catalyzed by alcoholdehydrogenase producing ethanol and carbon…
Which of the following is TRUE about termentation? O a. Alcohol fermentation is the kind of fermentation that occurs in human muscle cells O b. In lactic acid fermentation NADH donates hydrogen and becomes NAD+ which is reused by glycolysis O c. Fermentation begins at the end of glycolysis so the substrate for fermentation is glucose O d. Fermentation is an aerobic process which means it does not use oxygen O e. The reactants of alcoholic fermentation are yeast, sugar, and CO2
