L.11 Metabolism

Question 1

Draw an ATP Molecule

Answer 1

Question 2

What kind of energy level is ATP

Answer 2

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

A negative number means releasing energy, therefore spontaneous.

Question 3

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

Answer 3

1. Resonance
2. Ionization
3. Charge Replustion

Question 4

Hoe does ATP provide energy?

Answer 4

ATP provides energy through hydrolysis and coupling to energetically unfavorable reactions

Question 5

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

Answer 5

An electron carrier

Question 6

What are the two types of electron carriers?

Answer 6

Soluble and membrane bound

Question 7

What are flavoproteins?

Answer 7

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

Question 8

Name 5 Electron carriers

Answer 8

NADH (Glycolysis, Fermentation, Citric Acid Cycle, Electron Transport Chain)

NADPH (Pentose Phosphate Pathway, Lipid biosynthesis, Bleach Formation, Oxidative Stress, Photisysntheis )

CoQ Ubiquinone (Electron Transport Chain)

Cytochromes (Electron Transport Chain)

Glutathione (Oxidative Stress)
