1. Photosynthesis, Respiration and Energy - ATP

Question 1

What is the energy released from the glucose in respiration used to make?

Answer 1

ATP.

Question 2

ATP structure?

Answer 2

Nucleotide base adenine.
Ribose sugar.
3 phosphate groups.
Carries energy around cell.

Question 3

How is ATP synthesised?

Answer 3

Via a condensation reaction between ADP and inorganic phosphate using energy from energy releasing reaction. eg breakdown of glucose in respiration.
ATP Synthase.

Question 4

How is ATP energy stored?

Answer 4

Chemical energy in phosphate bond.

Question 5

ATP stores and releases a small manageable amount of energy, what does this mean?

Answer 5

No energy is wasted as heat.

Question 6

ATP is a small, soluble molecule, what does this mean?

Answer 6

Easily transported around cell.

Question 7

ATP is easily broken down, what does this mean?

Answer 7

Energy is easily released instantly and then its quickly remade.

Question 8

How can ATP make other molecules more reactive?

Answer 8

By transferring one of its phosphate groups to them - phosphorylation.

Question 9

ATP can’t pass out of cell, what does this mean?

Answer 9

Cell always has immediate supply of energy.
