Decay and Concepts

I was wondering, when do we use this formula, N = Noe-lambda(t).

Also, would it be a good idea to know all rate laws?

And, when they say its more conceptual based, likde what concepts in Gchem, secifically?
--Do they mean like photoelectric effect, balmer series, blackbody radiation etc.?

I was also wondering, what is the chemical formula for lipids (for example for carbs its CnH2nOn). Also, Are lipids the primary storage molecule?

glycerol and 3 fatty acids (carboxylic acid with long carbon chain) make lipids.

Fat is used for insulation of your body also. It does store the most energy per gram compared to carbo, protein..

This might be a stupid question but does lipid = fats, right! so lipids/fats are used for long term storage!! (i am stupid!)

Also, what are specific things we need to know about Ulva and Volvox

yes lipids = fat which are stored in your adipose (fat tissues)....

and you dont need to know all the rate laws...just distinguish it...btw you already know the first rate law if you know the decay...lol

N = Noe^-kt ....thats the same as the first rate law...but you do the natural log to keep it linear...

lnN = lnNo - kt

The reason I ask about the lipids is because I came across one question, in which it had 2 choices out of 4 that I thought was right instead of one. Here were the choices, are both of these right?

a. Lipids are long term energy storage
b. Lipids have C:n H:2n O:n formula

 

[DailyDrivenTJ]

I think the second choice incorrect. In lipids, there is a fraction of oxygen compared to carbon.

Thanks man! Realy appreciate all your help!!😀

carbohydrates have the ratio of C:H:O as in 1:2:1 (like what you put)
example:
glucose C6H12O6

fats have a bigger ratio of H's compare to O bonds, that is bigger than 2:1!!!(when breaking H's bonds it gives off more energy....!!!!thats why fats are the number storage of extra stuff!!!

Thanks, Yea I knew carbs had that formula, but the question picked CHO answer, and it confused me! So, figured I would ask you guys!!
