Coupling Reactions

Question 1

Bioenergetics

Answer 1

Transfer of energy from potential to kinetic

Question 2

Exergonic

Answer 2

Same as exothermic, releases energy

Question 3

Endergonic

Answer 3

Same as endothermic, consuming energy

Question 4

Coupling reactions is when….

Answer 4

when two reactions come together to make a reaction more favourable

Question 5

Biopolymers formation are usually….

Answer 5

intrinsically unfavourable reactions

Question 6

The reactions that are coupled is (….) and (…) reaction

Answer 6

endergonic, exergonic

Question 7

Endergonic reactions are….

Answer 7

unfavourable, which is why formations are usually unfavourable

Question 8

The addition of ATP to a biopolymer formation is used to….

Answer 8

make the reaction favourable as the hydrolysis of ATP releases more energy than the formation which makes the total energy favourable

Question 9

Kinetic vs Thermodynamic

Answer 9

Kinetic - energy needed to go over the activation energy
Thermodynamic - energy lost from the start to the end of reaction
