Energy, reaction and enzymes

Question 1

Potential Energy

Answer 1

Energy related to position

Question 2

Chemical Potential Energy

Answer 2

Energy in molecular form ( Based on position of electrons)

Question 3

Electrons far from atom- Low potential Energy
Electrons near atom- High potential Enegery

Question 4

Gibbs free energy

Answer 4

The energy within a molecule available to work (Free energy)

Question 5

Endergonic

Answer 5

1-Input of energy( Free energy increases)
2-Energetically unfavorble ( More effort)
3- Include anabolic reaction( Building)

Question 6

Exergonic

Answer 6

1-Release of energy (Free energy decreases)
2- Energetically favorable (less effort)
3-Includes catabolic reaction( Breaking down)

Question 7

Biological reaction- Reactants

Answer 7

take part in and undergo change in reactions

Question 8

Biological reaction- Product

Answer 8

Present at the end of reaction

Question 9

Activation energy

Answer 9

1- Energy input required to reach transition state

Question 10

Enzymes

Answer 10

1- Have a binding site=Active site
2- Have a unique and specific shape

Question 11

Enzyme regulation- Allosteric Regulation (other)

Answer 11

1- Bingding somewhere else not the active site
Activator or Inhibitor

Question 12

Enzyme Regulation-Competative Inhibition

Answer 12

Bind to active site

Question 13

Role of cofactors

Answer 13

Cofactors- Assist in Biochemical and transformation
Inorganic ions
can bing elsewhere

Question 14

Role of Coenzymes

Answer 14

Bind to active site and imporive subtrate binding
