Rate of Glucose uptake by yeast cells

AI Thread Summary
To investigate the rate of glucose uptake by yeast cells, a series of glucose concentrations should be prepared by diluting a 10% glucose solution with distilled water, creating concentrations of 5%, 1%, and 0.5%. The exact quantities for dilution must be calculated based on the desired final volumes and concentrations. The method involves measuring the yeast's glucose uptake at each concentration using Benedict's reagent to assess the results. It's important to determine how many readings are needed to ensure comprehensive data collection. Proper planning of the dilution process is crucial for accurate experimental outcomes.

You are required to plan an investigation to find out the rate of glucose uptake by yeast cells varies with glucose concentration

material resources
- 10% glucose solution
- disilled water
-yeast suspension
- Benedicts reagent
I have done the introduction, apparatus required, but I am unsure on what quantity i should use to make various glucose concentrations and i don;t know how to go about with the method :/
I was wondering if u guys be able to help me, thanksss

you have to dilute the glucose solution. you start with 10%, then 5%, 1%, 0.5%. it depends on how many readings you need.

to dilute you need to add a specific amount of water to the solution. you have to calculate that amount.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
