Answer:

i) Glucose

ii) β(1-4) glycosidic bonds.

iii) Oxygen

Explanation:

Cellulose is an important structural carbohydrate found in plants. It forms a major component of the plant cell wall.

Cellulose is a polysaccharide formed by monomers of glucose. These glucose monomers are joined together by covalent bonds called β(1-4) glycosidic bonds, which means that the 1st carbon of one glucose is bound to the 4th carbon of the next glucose. To make this arrangement, every other glucose molecule in cellulose is inverted, which you can see in the diagram.

Glucose monomers contain carbon, hydrogen, and oxygen only. If you look at the pattern of the molecule (remembering every second glucose is inverted), you can see that Z must be O.

The functional group denoted by Z is oxygen. The OH groups on the glucose from one cellulose chain form hydrogen bonds with oxygen atoms on the same or on another chain, holding the chains firmly together and forming very strong molecules - giving cellulose its strength.

Energy Generation in Aerobic and Anaerobic Conditions

Ira Lisetskai [31]

I wanted to be with you alone

And talk about the weather

But traditions I can trace against the child in your face

Won't escape my attention

You keep your distance via the system of touch

And gentle persuasion

I'm lost in admiration, could I need you this much?

Oh, you're wasting my time

You're just, just, just wasting time

Something happens and I'm head over heels

I never find out until I'm head over heels

Something happens and I'm head over heels

Ah, don't take my heart, don't break my heart

Don't, don't, don't throw it away
