ATP and Energy Supply Flashcards
1
Q
Name the two parts which make up ATP
A
ADP and an inorganic phosphate group
2
Q
What does he ATP reaction need to form?
A
Energy input
3
Q
Define phosphorylation
A
ATP transferring a phosphate to another molecule
4
Q
Why is a phosphorylated molecule better?
A
It is more reactive which lowers the activation energy needed for reactions
5
Q
Name the three types of oxidation reaction
A
- Removal of hydrogen
- Loss of electrons
- Combining with oxygen
6
Q
Name the three types of reduction reaction
A
- Addition of hydrogen
- Gain of electrons
- Removal of oxygen
7
Q
name five reasons cells use the energy in ATP rather than directly from glucose?
A
- ATP is small and soluble so it is easily transported around the cell
- Only releases a small amount of energy at a time so none is wasted
- Easily broken down so energy is released easily
- Can’t leave the cell, so the cell always has an immediate energy supply
- By transferring a phosphate group it can transfer energy to another molecule
8
Q
Name the enzyme which catalyses the break down of ATP
A
ATPase
9
Q
Name the enzyme which catalyses the formation of ATP
A
ATP synthase
