Question 5

What is Thermodynamics?

Answer 5

The study of energy and energy transformations.

Question 6

What are the two laws of Thermodynamics?

Answer 6

-First Law- Energy can be transformed between forms but cannot be created or destroyed
- Second Law- All energy transformations increase the entropy of the universe

Question 7

What is Entropy?

Answer 7

Entropy- The measure of disorder in a system

Question 8

What is an Exergonic Reaction?

Answer 8

Release of free energy; the product contains more energy than the reactant.

Question 9

What is a key example of an exergonic reaction?

Answer 9

Cellular respiration because it produces heat.

Question 10

What is a Endergonic Reaction?

Answer 10

stores free energy

Question 11

what is an example of an endergonic reaction?

Answer 11

photosynthesis because solar energy is being pushed into the cell

Answer 16

Phosphorylation

Question 17

what is Phosphorylation?

Answer 17

-The process in which ATP is continuously being getting regenerated
