Answer:
Fibre is the indigestible parts of plant foods, such as vegetables, fruits, grains, beans and legumes. It is type of a carbohydrate that helps keep our digestive systems healthy.
Answer:
(E) Phosphoglucose isomerase (phosphohexose isomerase or glucose-6-phosphate isomerase)
Explanation:
Glyocolysis is break down of glucose into pyruvate.
Isomerization:The second step of glycolysis involves the conversion of glucose-6-phosphate to fructose-6-phosphate (F6P). This reaction occurs with the help of the enzyme phosphoglucose isomerase (PI). As the name of the enzyme suggests, this reaction involves an isomerization reaction.
Yeast mutant lacking phopshoglucose isomerase unable to performed this step and that's why it unable to grow in media containing glucose while in fructose break down this step is not required so it is able to grow in media containing fructose.
Deletion of phosphoglucose isomerase, prevents growth on glucose; therefore, phosphoglucose isomerase mutant is able to grown in a fructose medium.
The linear sequence that passes energy from one organism to another is called the food chain. The energy is transferred starting from the Sun which is necessary for the plant's photosynthesis then move towards animals consuming plants as food. This is usually followed by humans eating animals like pigs and chickens for food.
The amount of p-nitrophenol relates to the cellobiase activity - The change in amount leads to a change in the yellow color of the reaction that presents only in presence of p-nitrophenol.
Cellobiase is an enzyme that catalyzes the hydrolysis of β1-4 glycosidic bonds found in cellulose. Organisms like fungus and some bacteria are able to break down cellulose with help of this enzyme. The substrate is cellulose and the product is glucose catalyzed by cellobiase. It is clear/colorless, and therefore difficult to detect quantitatively.
Enzymatic Activity of Cellobiase
- p-nitrophenyl glucopyranoside is used as a substrate which is an artificial substrate that binds to the Cellobiase and is broken down similarly to cellulose and produces glucose and p-nitrophenol.
- This p-nitrophenol reacts with a basic solution called stop solution that stops the reaction and turns the solution yellow.
- The amount of yellow color is proportional to the amount of p-nitrophenol present which means this color help in knowing the Cellobiase activity.
Thus, the change in amount leads to a change in the yellow color of the reaction that presents only in presence of p-nitrophenol.
