ATP and respiration

HideShow resource information
All living organisms gain their energy by which process?
Respiration
1 of 18
Is respiration a gradual or rapid release of energy?
Gradual
2 of 18
What does respiration provide the energy to produce?
ATP
3 of 18
What is ATP?
A nucleotide
4 of 18
What three things does ATP consist of?
An organic base, adenine, a 5-carbon sugar, ribose and a sequence of 3 phosphate groups linked together
5 of 18
Which bonds are unstable and easily broken?
The ones between the phosphate groups
6 of 18
What happens when the bonds between the phosphate groups are broken?
A considerable amount of energy is released
7 of 18
Which phosphate is usually removed in living cells?
The third one
8 of 18
What enzyme catalysts the reaction of ATP To ADP?
ATPase
9 of 18
The conversion of ATP TO ADP is what type of reaction?
Reversable
10 of 18
What is the equation for the removal of a phosphate group from ATP?
ATP +water = ADP + Pi + energy
11 of 18
What is activation energy?
The energy needed to start a chemical reaction
12 of 18
What is phosphorylation?
The addition of phosphate to ADP
13 of 18
What is the equation for phosphorylation?
Energy + P1 + ADP = ATP + water
14 of 18
What are the three forms of phosphorylation?
Oxidative phosphorylation, photophosphorylation and substrate-level phosphorylation
15 of 18
Where does oxidative phosphorylation occur?
On the membranes of mitochondria during aerobic respiration
16 of 18
Where does photophosphorylation occur?
On the membranes of the chloroplasts during photosynthesis
17 of 18
When does substrate- level phosphorylation occur?
When phosphate groups are transferred from donor molecules to ADP to make ATP
