Question

What are two functions of carbohydrates in living organisms?


A. structural components and information storage


B. energy storage and protein synthesis


C. enzymatic reactions and structural components


D. energy storage and enzymatic reactions


E. structural components and energy storage

Answer 1

It should be C.

Answer 2

Carbohydrates are Polysaccharides wich are used in energy processes.

Answer 3

which*

Answer 4

I'm honestly going to have to disagree and go with E. But I could be wrong.

Answer 5

I'd go with E, too. Glucose is an example for energy storage and cell walls consist of different types of carbohydrates which would count for the structural components.

Answer 6

The answer is E

Answer 7

Yep, C would be for proteins , as enzymes = proteins

Answer 8

C

Answer 9

ok guys ans is E but u all are saying C so i want to keep the point in front that is there any need of carbohydrate for enzymatic reaction.. becoz we all v.well know that for enzymatic reaction the substrate and prosthetic group and inhibitor these are also matter which can inhibit the reaction or play the reaction sso if we go through other options we find E is right.

Answer 10

But energy is stored in the form of glycogen in humans and glucose in plants. Rite?

Answer 11

yes.but remember whenever carbohydrate word cames first thing should be energy in ur mind as when we break carbohydrate energy is release so we call it energy storage now coming to ur option C tr. of components we can also say it but nw if u look options there energy storage is in D ad E a i said above there is not much specific role in enzymatic reaction so ans goes to E

Answer 12

str. of components forms by the need of energy required to play its metabollic activities

Answer 13

Thanks a lot. My doubt got cleared. Cheers!!!!!!!!

Answer 14

glad to listen that ur doubt cleared

Answer 15

Yeah just becoz of u. Thanks a lot. Hope u clear all my doubts.

Answer 16

yarp. E is right. but, A is also possible. I will tell you, why.

every cell of higher organisms knows which organism it belongs to. this is why, when you get an organ transplant, you need to take heavy medication to suppress an immune response, because your organism knows exactly which cells belong to it and which don't.

this is done through unique sugar codes on the surface of your cells.

I will take it one step further: even your different body tissues that aren't in contact with each other have got different sugar codes. this way, you don't suddenly grow a kidney on your foot. if a cell gets washed away from its destined location, it will die because the sugar codes of the target tissue don't match its own! cool, huh?

however, cancer cells often don't care about that and still grow wherever they want, in a certain stage of disease.

and since identity IS information, sugar also store information. and are better at that than our DNA itself! because DNA does not have an equal information density, on molecular level. but this is another topic. sugars are more labile and the process of producing the sugar code is way more expensive than copying some DNA.

Answer 17

thnkz for ur xtra info sir hope it helps me in future when i study abu dis..... :)
but schlieifspur what u said is right but mainly we will consider energy storage right so by looking option we go for E first .

Answer 18

U r rite Heena didi!!!!!!!! Yet this question is sooooooo confusing.
