Question

Consider the following metabolic reaction:

phosphoarginine + ADP ?> arginine + ATP
Which of the following statements is TRUE?
i) This reaction is a substrate level phosphorylation reaction
ii) This reaction is catalyzed by an isomerase
iii) This reaction is a phosphate transfer reaction
iv) This reaction is a redox reaction
v) This reaction is a coupled reaction
a) i and iii are true
b) iv and v are true
c) i, iii, and v are true
d) i, ii, iii, iv and v are all true
e) i and ii are true

Answer 1

C

Step-by-step explanation:

* A phosphate level phosphorylation reaction is one that results in the generation of ATP.

*The reaction involves a phosphate transfer to ADP to form ATP.

*A coupled reaction in biochemistry is a form of reaction in which a form of energy is produced from another form of energy e.g. generating ATP (a higher energy compound) from ADP (a lower energy compound).
