Question 16
Question
The enzyme responsible for making ATP is [blank_start]ATP[blank_end] [blank_start]synthase[blank_end].
Question 17
Question
How does ATP differ from other energy storage molecules, such as starch or glycogen?
Answer
-
It's a less stable molecule, so not used for long-term storage.
-
It is known as the universal energy currency because it releases energy in greater quantities.
-
Energy release from ATP is a multi-step process.
-
ATP is a polymer which has only one type of monomer.
Question 18
Question
What type of reaction is required to release energy from ATP?
Answer
-
Hydrolysis
-
Condensation
-
Polymerisation
-
Combustion
