Energy and ATP

Question 1

What is ATP made from

Answer 1

nucleotide base adenine, ribose sugar and 3 phosphate groups

Question 2

How is ATP released

Answer 2

Via a hydrolysis reaction and diffused to parts of the cell that need energy

Question 3

When energy is needed by a cell what happens to ATP and how

Answer 3

It breaks down in to ADP and inorganic phosphate
Catalysed by ATP hydrolase
The released phosphate can be added to another compound - phosphorylation which makes a compound more reactive

Question 4

How can ATP be re-synthesised

Answer 4

Condensation reaction between ADP and P catalysed by ATP synthase

Question 5

Role of Hydrogen ions

Answer 5

The more hydrogen ions present the lower the Ph of an environment and enzyme controlled reactions are all affected by PH.
Help control PH in digestion
Released during various metabolic reactions

Question 6

Role of Sodium ions

Answer 6

A mol of glucose or amino acids can be transported across a cell alongside a Na ion - co transport
