Question

Q2) Complete the following reactions:-

1) Starch when reacts with amylase

2) Carbon dioxide and water utilize in presence of sunlight

3) Glucose oxidise to produce energy

4) Yeast commercially produces ethanol​

Answer 1

1. 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. Photosynthesis is the process in which autotrophs such as green plants use carbon dioxide and water in presence of sunlight to synthesize nutrients such carbohydrates in the form of glucose and release oxygen. In this carbon dioxide is reduced to glucose and water is oxidized to release 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. The yeast species involved in alcohol production transport sugar into their cells where it can be used to extract energy through two processes depending on the presence, or absence, of oxygen .The process of ethanol fermentation generates waste products, ethanol and carbon dioxide, from pyruvate .

Answer 2

Answer:

1) Forms Glucose

2) Forms Glucose or C6H12O6

3) Forms ATP, CO2, H2O

4) Glucose ----------->Ethanol + CO2
