ATP Flashcards
What is the immediate source of energy in a cell?
ATP
By what process do plant and animal cells do to release energy?
respiration
What is ATP formed from?
Adenine, ribose sugar and three phosphate groups
What does ATP stand for?
Adenosine triphosphate
what is adenosine formed from?
adenine, ribose sugar
What is AMP formed from?
Adenine, ribsoe sugar and one phosphate group
What is ADP formed from?
Adenine, ribose sugar and two phosphate group
Where is energy stored in the ATP molecule?
Bonds between the phosphate groups
The energy is released via what type of reaction in the ATP molecule?
Hydrolysis
When energy is needed by the cell, what is ATP broken down into?
ADP and phosphate
What type of reaction resynthesises ATP from ADP and Pi?
Condensation
What is the term used to describe the inorganic phosphate joining to other compounds and making them more reactive?
phosphorylation
what is the name of the enzyme that converts ATP to ADP?
ATP hydrolase
What are the products of ATP hydrolase activity?
ADP, inorganic phosphate and energy
What is another name for the enzyme ATP hydrolase?
ATPase
what type of reaction does an ATPase catalyse?
Hydrolysis
what is the name of the enzyme that converts ADP to ATP?
ATP synthase
as well as ADP, what does ATP synthase require for the formation of the ATP?
Inorganic phosphate and energy from respiration
what type of reaction does ATP synthase catalyse?
condensation
which of the following statements best explains why ATP is useful for storing energy?
the bonds between the three phosphate groups are highly unstable and when broken release a considerable amount of energy
What is the immediate energy source and why?
ATP because of the instability of the phosphate bonds
which of the following energy sources cannot be stored in large quantities?
ATP
Which of the following porcesses is not powered by energy derived from ATP?
movements of solvents into a cell by osmosis
