7.1 Energy in Living Systems

Question 1

dephosphorylation

Answer 1

removal of a phosphate group from a
molecule

Question 2

Hydrolysis

Answer 2

the process of breaking complex macromolecules apart

Question 3

. Phosphorylation

Answer 3

addition of a high-energy phosphate to a
compound, usually a metabolic intermediate, a protein,
or ADP

Question 4

substrate-level phosphorylation

Answer 4

A phosphate group is removed from an intermediate reactant in the pathway, and the free energy of the reaction is used to add the third phosphate to
an available ADP molecule, producing ATP

Question 5

Chemiosmosis

Answer 5

a process of ATP production in cellular metabolism,
-used to generate 90 percent of the ATP made during glucose catabolism

Question 6

oxidative phosphorylation

Answer 6

The production of ATP using the process of chemiosmosis (because the involvement of oxygen)
