Biological Molecules

1)What is a nucleotide made from

2) What bond joins a nucleotide

3)Differences between DNA and RNA

4)Why is DNA stable

1)Phosphate group,Penrose sugar and Nitrogen base

2)Phosphodiester bond

3)DNA=Double stranded,Deoxyribose and ATCG RNA=Single stranded,Ribose and AUCG

4)Hydrogen bonds

1)What bond forms between two monosaccharides

2)What reaction forms a glycosidic bond

3)What reaction breaks a glycosidic bond

1)Glycosidic bond

2)Condensation

3)Hydrolysis

1)What is the role of iron ions

2)Role of phosphate ions

3)Role of hydrogen ions

4)Role of sodium ions

1)Bind to oxygen

2)Form ATP,DNA,RNA and phospholipids

3)Affect pH and enzyme function

4)Helps in co transport

What does ATP stand for

Adenosine triphosphate

What is ATP made from

Adenine, ribose, 3 phosphate groups

What happens during ATP hydrolysis

ATP → ADP and pi

Why does ATP releases energy

Breaking phosphate releases energy, bond is unstable
