Complete the following reactions -
1) Starch when reacts with amylase
2) Carbon dioxide and water utilize in presence of sunlight
3) Glucose oxide to produce energy
4) Yeast commercially produce ethanol.
Answers
Explanation:
(1) Amylase Enzyme
It catalyzes the breakdown of starch. When amylase reacts with starch, it cuts off the disaccharide maltose (two glucose molecules linked together). As the reaction progresses, less starch will be present and more sugar (maltose) will be present. The activity of amylase can be observed by using iodine.
(2) The chlorophyll absorbs sunlight and the carbon dioxide and water absorbed from the leaf and roots respectively. 6 moles of Carbon dioxide combines with 12 moles of water in presence of sunlight and chlorophyll gives 1 molecule of glucose, 6 moles of water and 6 moles of oxygen
(3) The primary function of the oxidation of glucose to CO2 in the glycolytic pathway and the citric acid cycle is to produce NADH and FADH2, whose oxidation in the mitochondria generates ATP.
(4) Compared to other types of microoganisms, yeasts especially Saccharomyces cerevisiae is the common microbes employed in ethanol production due to its high ethanol productivity, high ethanol tolerance and ability of fermenting wide range of sugars.
