Q

Nucleotides

A

Nucleotides are key molecules in Biology. They provide the energy currency of cells in the form of adenosine triphosphate, usually referred to as ATP. They also provide the building blocks for the mechanism of inheritance in the form of DNA - deoxyribonucleic acid - and RNA - ribonucleic acid.

2
Q

Nucleotides - 2

A

Nucleotides are molecules with three parts - a 5 carbon pentose sugar, a nitrogen-containing base and a phosphate group - joined by condensation reactions.

3
Q

Adenosine triphosphate(ATP)

A

Adenosine triphosphate (ATP) is a nucleotide that acts as the energy supply molecule in cells. It is made up of the base adenine, the pentose sugar ribose and three phosphate groups.

4
Q

Purine base

A

A purine base is a base found in nucleotides that has two nitrogen-containing rings.

5
Q

Pyrimidine base

A

A pyrimidine base is a base found in nucleotides that has one nitrogen-containing ring.

6
Q

Adenine

A

Adenine is a purine base found in DNA and RNA.

7
Q

Guanine

A

Guanine is a purine base found in DNA and RNA.

8
Q

Cytosine

A

Cytosine is a pyrimidine base found in DNA and RNA.

9
Q

Thymine

A

Thymine is a pyrimidine base found in DNA.

10
Q

Uracil

A

Uracil is a pyrimidine base found in RNA.

11
Q

ATPase.

A

ATPase is an enzyme that catalyses the formation and the breakdown of ATP, depending on conditions

12
Q

Adenosine diphosphate(ADP)

A

ADP is nucleotide formed when ATP loses a phosphate group and provides energy to drive reactions in the cell.

13
Q

Reduction/oxidation (redox)

A

Reduction/oxidation (redox) reactions are reactions in which one reactant loses electrons(is oxidised) and another gains electrons ( is reduced).
