part one

Question 1

oxidation

Answer 1

the loss of electrons

Question 2

reduction

Answer 2

gain of electrons

Question 3

substrate-level phosphorylation

Answer 3

uses ATP that is formed directly by the transfer of a phosphate group to ADP using an enzyme

ATP is created

Question 4

oxidative phosphorylation

Answer 4

uses ATP that is formed indirectly by the transfer of a phosphate group through redox reactions

ATP is created

Question 5

how are substrate-level phosphorylation and oxidative phosphorylation different

Answer 5

-substrate-level phosphorylation- is when ATP formed directly by the transfer of a phosphate group to ADP using an enzyme
-oxidative phosphorylation- is when ATP is formed indirectly by the transfer of a phosphate group through redox reactions
