Science – Yeast Experiment: measuring respiration in yeast – Think like a scientist (8/10)

no matter how match sugar i use, the balloon infaltes just a litle bit. It doesnt stretch. what could possible is wrong?

This one time, i got so sick

Can someone tell me easiest and fast way to know it it is so long















If anyone is from cms Cambridge 7th A lucknow aligang it's me Atharv Srivastava

Not even telling us how much glucose we need, motherfucking noob!

That's me rn Last minute work

CAN SOMEONE PLEASE SUMMARIZE ( ITS FOR SCHOOL ) THANKYOU <33

but why we boiled water

it's extremely helpful

Chill lady slow down

I know your voice from learning english

Oh my I need help, this is for my project, what's the independent, dependent, control, and constant variable in the experiment?

gen bio :)))) pain

Why did you put a covering over the last one (the one with blood temp water)? Wouldn't that change what happened to that one compared to the other three.

online class in microbiology required us to watch this 🙋

ignore me im tryna culture a deadly bacteria

POV: You're an American and you were brought here by your Openstax bio textbook lol

hey guys i had to do this for my bio class but im not good at bio. i have to explain why she got those results can someone help

OMS

Reply here if you're here for some boring school work like meh 🙄😡🤣

Yeast is important... understanding its reproduction can also be useful... especially if you don't wanna buy yeast to make your moonshine.... MMMMMKAY

my science teacher said i could do this LIKE I HAVE YEAST AT HOME (because i don't)

wait i thought you already had yeast in the beginning did yo put it twice or was that water

Hello my school

hello aaron

love yeast. big fan.

HEr because school

Hi

POV: your here because your doing science for online school

POV: Your here for online school

pov: ur watching this bc ur school made you

For the hot one you cover it with a vloth

how to calculate the growth rate ?

Ignore this it’s For school,

1. First take 4 empty glasses and place put an equal amount of sugar (one spoonful) in each one.
2. For one glass pour an amount (just roughly less then half the glass) of cold water
3. Now for the second one, pour in the same amount but with boiled water.
4. After completing 2 & 3, pour in water of body/ blood temperature into the last two remaining glasses (you may test the temperature before hand, by dipping in your finger)
5. Give all the liquids a stir (not too much that the sugar starts dissolving completely)
- On a sheet of paper you can label which glass is which.
7. Now add a sachet of yeast to each glass
8. After, Mark the current level of water on the side of the glass (accurately)
9. For the last glass (4th one with blood temperature water) cover it with cling film to restrict the amount of air that the yeast has, to work with.
10. Now set the experiments to set for 5 minutes
11. After the 5 minutes have past, you will notice that the yeast has risen, just like in the way bread does.
12. Now, to keep track of this process you will need to measure the thickness of the foam and record how it changes over time (use a ruler) - writes down the result of 5 minutes on a sheet
13. Wait another 5 minutes, which makes up 10 minutes over all

I'm guessing your here from school too😐

thank you so much this has helped me for a school experiment

More than half of this is students watching this for schoolwork or homework

Pov: You're doing your biology IA, from home due to Covid and your teacher :)

hi tidiane

Yeah is there another way I could record this.

Uhh nothing happened for me

Pov: your here because of school

ok : )

I have questions. what do yeast needs to survive and does respiration needs more energy than photosynthesis? explain the answer thank youuu

Okay so if this is to teach science, 1 dont touch your samples, potentialy exposing them to microbes. 2. Dont use the same spoon...

Great amazing good fabulous

Why did you decide to make a 5min break?

Hi! I have a question. Is it possible for the sucrose to produce more co2 and have a faster rate given that it needs to be brokendown first into glucose by the enzyme coming from yeast? rather than the readily glucose?

is this video, real, for real? 🤨

Why is sugar added in the experiment?

what is the yeast rises more in the hot glass than the room temperature glass? does that mean heat is produced during cellular respiration?
