ATP Flashcards
Plants and animals need energy for
Biological processes to occur
Plant and animal cells receive energy from
glucose
A cell can’t get it’s energy directly from glucose, so in respiration, the energy released from glucose is used to make
ATP
What does ATP stand for
Adenine triphosphate
What is ATP made from
The nucleotide base adenine, ribose sugar, three phosphate groups
ATP is a nucleotide derivative because it’s a
modified form of a nucleotide
Once made ATP diffuses to the
part of the cell that needs energy
The energy in ATP is stored in
High energy bonds between the phosphate groups
How is ATP energy released
Via hydrolysis reactions
When energy is needed by a cell, ATP is broken down into
ADP and Pi(inorganic phosphate)
What does ADP stand for
Adenine Diphosphate
What reactions turns ATP to ADP+Pi
Hydrolysis reaction
What reaction does ATP hydrolase catalyse
ATP—> ADP+Pi
ATP hydrolysis can be coupled to other energy-requiring reactions in the cell, what does this mean
That the energy released can be used directly to make coupled reaction happen rather than being lost as heat
What is a coupled reaction
A chemical reaction having a common intermediate in which energy is transfered from one side of the reaction to the other.
