BIOLOGY people - can you please help me design an anaerobic respiration experiment?

Question

can you please help me design an experiment that investigates the effect of temperature on the rate of anaerobic respiration?

we must use a a glass apparatus that volumetrically collects gasses emitted from liquid solution.

i'm not trying to get someone to do my homework for me, we're allowed to get help on this part. doing the actual experiment is the big thing, but i'm not even sure how to go about designing it.

any help is greatly appreciated :)

Answer 1

You should use yeast in your experiment because it is one of the most easily attainable substances (grocery store). With yeast, it is very important to have sugar dissolved in the water.

Test the differences in amounts of gasses emitted from yeast at different temperatures of water. In your water you should have the sugar and yeast. Perhaps the yeast package will have some sort of quantity of sugar you will need. If not, then look for a recipe that involves yeast, such as bread that needs to rise (not quick breads). Think along the lines of cinnamon roll dough.

I hope that this helped.

Answer 2

First, since temperature is the variable, you would need to have methods of varying the temp of your experimental tubes. You would put the same amount of yeast, water, substrate, etc., in glass tubes. The tubes would be stoppered, with a glass "straw" in the stopper going through the stopper to a manometer, which measures the amount of gas produced. Then, each tube would have to be maintained at a different temperature (perhaps by putting them in heat blocks) and monitored (to make sure the temp remains the same) and measure the amount of gas produced in each.

Answer 3

the chances of a good scientist here on answers is kinda low, and the chance of them answering it is lower... but maybe you should ask your teacher or whoever assigned you this to get help
