1

Draw an ATP Molecule

2

What kind of energy level is ATP 

ATP is a mid-level energy molecule providing -30.5 KJ/mol

A negative number means releasing energy, therefore spontaneous.

3

How are the high energy phosphates groups in ATP stabilized upon hydrolysis?

  1. Resonance
  2. Ionization
  3. Charge Replustion

4

Hoe does ATP provide energy? 

ATP provides energy through hydrolysis and coupling to energetically unfavorable reactions

5

Many oxidation-reduction reactions involve __________ to transport high-energy electrons.

An electron carrier

6

What are the two types of electron carriers?

Soluble and membrane bound

7

What are flavoproteins?

Are one subclass of electron carriers that are derived from riboflavin B2.
