Homework Answers

Answer #1

2)First options means the primary structure.

The second option means the tertiary structure .

Third option means secondary structure.

Fourth option means the quarternary structure.

So answer is second option.

A)Carbohydrates are the most readily available source of energy for the body.

Enzymes are proteins; nucleic acids contain the genetic information found in cells,proteins are made up of C,H,O,N atoms and lipids and proteins make up the cellular membrane.

B)Fatty acids

C)They are called neutral solutions.

D)Phospholipid

E)Sucrose (glucose +fructose) ,Lactose (glucose + galactose)

F)Five carbon sugar, nitrogenous base,phosphate group

G)They are different because of the structure of the side chain.

H)Nucleic acids

J)Prostaglandins
