ATP

Question 1

Purpose of ATP

Answer 1

Release energy through exergonic reactions to provide energy so endergonic reactions can occur

Question 2

structure of ATP

Answer 2

Three phosphate groups attached to adenosine.
An adenosine is 5 carbon ribose sugar and an adenine (unit composed of adenine)

Question 3

How is energy released from ATP

Answer 3

during hydrolysis, water is added and the third phosphate group (loosely attached) is removed
Reaction catalysed by ATPase
Produces ADP

Question 4

How is ATP synthesised

Answer 4

The anabolic reaction catalysed by ATP synthase which requires energy to attach the phosphate group to the ADP

Question 5

Where is the energy for atp synthesis from

Answer 5

catabolism of glucose in respiration

Question 6

Anaerobic phase of respiration

Answer 6

Glucose partial broken down in the cytoplasm of cell
Energy released from this can synthesise 2 ATP. Each molecule of glucose is converted into pyruvic acid

Question 7

Aerobic phase of respiration

Answer 7

Complete breakdown of glucose occurring in mitochondria forming CO2 and water
This generates heat and 30 - 32 ATP
