Q

What is good about ATP being an immediate energy source?

A

Small amount are released
Enough energy to drive important metabolic reactions while keeping energy wastage low-means cells do not overheat from wasted heat energy (keep cell temperature low) and cells are less likely to run out of resources

16
Q

Phosphorylates compounds?

A

Making metabolites more reactive- lowering the Ea of the reaction

17
Q

Phosphorylates compounds?

A

Making metabolites more reactive- lowering the Ea of the reaction

18
Q

Soluble?

A

Can move from cell to cell- can transport energy to different areas of the cell

19
Q

ATP cannot be…

20
Q

ATP can be….

21
Q

Is hydrolysis quick?

A

Yes- it is quick and easy- allows cells to respond to a sudden increase in energy demand
Only one bond is hydrolysed to release energy- energy release is immediate.

22
Q

Metabolic processes?

A

ATP provides energy to build up macromolecules

23
Q

Movement?

A

Provides energy for muscle contraction

24
Q

Active transport?

A

Provides energy to change carrier proteins in the membrane

25
Secretion?
ATP is needed to form lysosomes
26
Activation of molecules?
Phosphorylation of other compounds- lowering the Ea
27
Transferring one of its phosphate groups?
Can transfer energy to another molecule by transferring one of its phosphate groups
28
Can ATP pass out of the cell?
No so the cell always has an immediate supply of energy
