Cell Metabolism Part 2 Concept Review

a. primarily stored between the alpha and beta

phosphates

b. equal to −57 kcal/mol

c. harnessed as heat energy by the cell to perform

work

d. providing energy to coupled reactions

a. sucrose

b. ATP

c. glucose

d. ADP

a. They increase ΔG of reactions

b. They are usually made of amino acids

c. They lower the activation energy of chemical

reactions

d. Each one is specific to the particular substrate(s)

to which it binds

a. Binds to an enzyme away from the active site

and changes the conformation of the active site,

increasing its affinity for substrate binding

b. Binds to the active site and blocks it from

binding substrate

c. Binds to an enzyme away from the active site

and changes the conformation of the active site,

decreasing its affinity for the substrate

d. Binds directly to the active site and mimics the

substrate

a. A hug between two people

b. A key fitting into a lock

c. A square peg fitting through the square hole and

a round peg fitting through the round hole of a

children’s toy

d. The fitting together of two jigsaw puzzle pieces.
