QUESTIONS of COz produced (look at Eq 1 tub repiration), wmolecie ot O, for gach molecula tube? Why? Since the pea seeds consume change would you predictithere was no KOH placed in the test 1C) know about the 2. seed respiration? Use what you What effect does temperature have on the rate of pea effect of temperature on enzyme rate to explain your resulits 3, Do both seeds and yeast produce CO.? 4. Do both seeds and yeast consume O:? 5. What gas are you measuring for seed respiration? What gas for yeast respiration? Which gas producesExplanation / Answer
1.KOH absorbs CO2 produced during respiration.If there was no KOH placed in the test tube, CO2 produced during respiration will not be removed from the test tube and hence there will be an increase in volume of CO2 inside the tube as a result of which the water level will not rise in the tube.Also, there will be reduced respiration.
2.As temperature rises, the rate of respiration will also rise due to increased speed of chemical reactions that in turn increases the kinetic energy.Again, the rate of respiration increases with increase in temperature but within a defined temperature range i.e optimal temeprature conditions.Beyond the optimal temeprature, the respiration process will slow down.This is because cellular respiration depends on the action of enzymes that work best under certain optimal temperatures and their activity is lost at higher temperatures.
3.Yes,both seeds and yeast produce CO2 during the process of cellular respiration.
4.Yes,both seeds and yeast consume oxygen as a part of the process of cellular respiration.
5.For seed germination, we are measuring the decrease in oxygen and for yeast respiration, we are measuring the increase in carbon dioxide gas.The oxygen gas produces a decrease in volume and the carbon dioxide gas produces an increase in volume.The difference is because oxygen is consumed during respiration while carbon dioxide is produced during respiration.
