Q

What are the three main types of activity that cells require energy for?

A

Synthesis eg. large molecules such as proteins, Transport eg. pumping ions across cell membrane by active transport, Movement eg. protein fibres in muscle cells which cause muscle contraction

Q

What is the diagram to show the interconversion of ATP and ADP

A
17
Q

Why is ATP not a good long-term energy store, and why do cells not need a large ATP store?

A

Due to the instability of the phosphate bonds. This means that cells do not store large amounts of it but it ATP is being rapidly reformed by the phosphorylation of ADP though a condensation reaction, meaning the cells do not need a large store of ATP as it is a good immediate energy source

18
Q

Where is the energy released from using the hydrolysis of ATP?

A

Energy is released from the phosphate bond and used up by the cell

19
Q

What are the properties of ATP?

A

Small - moves easily into, out of and within cells
Water soluble - energy-requiring processes happen in aqueous environments
Contains bonds between phosphates with immediate energy - large enough to be useful for cellular reactions but not so large that energy is wasted as heat
Releases energy in small quantities - quantities are suitable to most cellular needs, so that energy is not wasted as heat
Easily regenerated- immediate energy source, can be recharged with energy
