Q2: Energy Coupling

Question 1

A process where energy generated from one reaction is used to drive the second reaction.

Answer 1

energy coupling

Question 2

It is the pairing of two biological reactions where one generates energy as in its process while another consumes energy to continue its process.

Answer 2

energy coupling

Question 3

Energy-releasing reactions (thus, energetically-favorable)

Answer 3

exergonic reactions

Question 4

Energy-demanding reactions (thus, energetically-unfavorable)

Answer 4

endergonic reactions

Question 5

True or False

Endergonic and exergonic refer to changes in internal energy of molecules (ΔH).

Answer 5

False

Question 6

True or False

Endergonic and exergonic refer to free energy changes (ΔG), which also results to change in entropy (ΔS).

Answer 6

True

Question 7

The measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work.

Answer 7

entropy

Question 8

It is an energetically favorable reaction is directly linked with an endergonic reaction through a shared intermediate, where a product of one reaction is “picked up” and used as a reactant in the second reaction.

Answer 8

reaction coupling

Question 9

2 types of metabolisms going on inside the cells

Answer 9

• anabolism
• catabolism

Question 10

A type of metabolism that require energy to happen.

Answer 10

anabolic reaction

Question 11

A type of metabolism that produces energy when it happens.

Answer 11

catabolic reaction
