Paul Andersen explains how a respirometer can be used to measure the respiration rate in peas, germinating peas and the worm. KOH is used to solidify CO2 produced by a respiring organism.

KOH is a strong base, meaning that it dissociates completely in water. It also means that if any of it came in contact with the peas, the peas would be completely fried and the experiment wouldn't work. To correct this, we dip absorbent cotton balls into the KOH first, put it at the bottom of the respirometer, and cover it with NON ABSORBENT cotton. This provides a barrier between the KOH and the peas while still allowing O2 to pass through.

Why is the equilibration period necessary? What happens during that period? I understand the rest of the experiment but that part is kind of glossed over in most explanations.

I love your explainations! Btw, could you please please make a video on Cellular Respiration and the Kerbs Cycle? because when you explain it I understand completely and way better than me just reading off from the textbook! (the most difficult part is the process) Thank you for uploading so many wonderful videos! It really helped me lot ! :) I can't wait for more of your videos! You rock!

Does anyone understand the influence of temperature on the rate of cellular respiration? Like, what affect does and increase or decrease have?

@Cloroxbleach-bt8jh 5 жыл бұрын

Because when the temperature is higher there is greater kinetic energy, i believe, which speeds up the process and when temperatures drop in order to conserve energy the process slows

@MrDarren690 4 жыл бұрын

Jesus Christ, it's just gas volume. Yeah the kinetic energy is greater but that's a stupid way of saying "the gas has more volume". Being smart for the sake of being smart doesn't help anyone.

Independent is what is changed or manipulated, so it is the contents of the vials (germ/non-germ peas, beads). Dependent is the outcome, so oxygen consumption (by amount of water pulled in), Control is the one with just beads.

If that statement were to have the slightest merit, it would be directed at evolutionary biology, the study of the origin and evolution of life. Biology is concerned with the biological systems that beget and appropriate life. If you're going to insult a science, you may want to make sure you're insulting the right one. But I'm sure the scientific community would love to hear your ideas of human origin and study the vast amounts of information that corroborate your hypothesis. Oh, wait...
