ATP 3.11

Question 1

Reasons why cells require energy

Answer 1

Synthesis
Transport
Movement

Question 2

ATP

Answer 2

Adenosine Triphosphate which is composed of an adenine base, a ribose pentose monosaccharide and three phosphate groups

Question 3

Universal energy currency

Answer 3

ATP is universal energy current as it is used for energy transfer in the cells of all living things

Question 4

How ATP releases energy

Answer 4

It takes a small amount of energy to break the last phosphate off of the ATP and it creates a lot more energy when that phosphate undergoes other reactions.

Question 5

Hydrolysis reaction

Answer 5

ATP + water —> ADP + Phosphate ion + energy

Question 6

Condensation reaction

Answer 6

Also known as the phosphorylation of ADP where water is removed to create ATP again and this requires energy as well. This is very quick to happen and is why ATP is an immediate energy store

Question 7

Long term energy stores

Answer 7

ATP is not a long term energy store because of the unstable phosphate bonds, however lipids and carbs are good

Question 8

Properties of ATP

Answer 8

Small
Water Soluble
Contains bonds between phosphates with little energy
Releases energy in small quantities
Regenerates quickly

Question 9

How is ATP made

Answer 9

ATP is formed from a process involving glucose and oxygen called respiration
