Kinetic and potential energy/ chemical energy/laws of thermodynamics

Question 1

kinetic energy

Answer 1

energy associated with movement

Question 2

potential energy

Answer 2

energy is stored

Question 3

Relationship between potential energy and strong bonds

Answer 3

The stronger the bond the less potential energy it has stored

Question 4

Relationship between stable bonds and potential energy

Answer 4

The more stable a bond is the less potential energy it has

Question 5

The chemical structure of ATP

Answer 5

1. adenosine: base adenosine
2. 5 carbon sugar ribose
3. 3 phosphate group

Question 6

The first law of thermodynamics

Answer 6

energy can not be created or destroyed

Question 7

The second law of thermodynamics

Answer 7

the amount of disorder increases when energy is transformed

Question 8

Entropy

Answer 8

is the degree of disorder

Question 9

Effect of carbon dioxide in an enviorment?

Answer 9

Turns the environment acidic because more H+ protons are released

Question 10

In an exergonic reaction

Answer 10

• G= negative
• Spontaneous reaction
• Products have more free energy then the reactants

Question 11

Enthalpy

Answer 11

the total energy available

Question 12

In chemical reactions if products have shorter, stronger covalent bonds than the reactants

Answer 12

• the potential energy in the bonds decreases
• the change in energy turns to light/heat

Question 13

Energy coupling

Answer 13

The use of an exergonic reaction to fuel an endergonic reaction
1. endergonic reaction
2. exergonic process (ATP hydrolysis)
3. End with a negative kcal

Question 14

ADP; energy donor or acceptor

Answer 14

energy acceptor

Question 15

ATP; energy donor or acceptor

Answer 15

energy donor
