Lecture 12-13

Question 1

entropy

Answer 1

complexity of system (more/less order)

Question 2

low entropy

Answer 2

= more ordered

Question 3

high entropy

Answer 3

= less orderd

Question 4

free energy

Answer 4

amount of energy in a system that is free to do work
- is difference b/w total energy in a system and the degree of entropy it has

Question 5

exergonic

Answer 5

negative delta G= give up free energy
- energy released
- spontaneous at 37 degrees

Question 6

endergonic

Answer 6

+ delta G = gained free energy
gain charge
energy required
nonspontaneous

Question 7

spontaneity

Answer 7

tendency of a physical or chemical change to proceed spontaneously

Question 8

glucose and entropy?

Answer 8

glucose is transformed from a less stable and more complex state (LOW entropy) to a more stable and less complex state (HIGHER entropy)

Question 9

release of energy in small packets

Answer 9

by pulling a small amount of energy off at each step of a cascade type reaction to generate the small pack of energy without releasing tons of heat

Question 10

what molecule couples’ endergonic and exergonic rxns

Answer 10

ATP

Question 11

ATP cycle
