Biochemical reactions (German) - week 5

Question 1

Define a chemical reaction

Answer 1

Changes in molecular structure performed through work

Question 2

Name the 5 common biochemical reactions

Answer 2

1. Making and breaking Carbon bonds
2. molecular re arrangements
3. free radical rxns
4. group transfers
5. REDOX rxns

Question 3

What is a condensation rxn?

Answer 3

(Aldol & Claisen ester) 2 molecules join to create a larger molecule, while also forming a byproduct

-Type of making or breaking carbon bond rxn

Question 4

What is a free radical?

Answer 4

A molecule containing an unpaired electron

dopamine quinone formation & Vit. E

Question 5

What is a REDOX RXN

Answer 5

paired of reactions that move electrons to perform work (Reduction requires energy & Oxidation releases energy)

Remember: OIL RIG

Question 6

What are the 4 ways to transfer e-

Answer 6

1. Direct e- transfer
2. H atom transfer
3. Hydride ions (H-)
4. Combination w/ O2

Question 7

What is free energy?

Answer 7

Free energy is released or consumed to perform work. Anytime a reaction occurs within the body the body uses or releases free energy

Question 8

How is ATP involved in group transfers?

Answer 8

The more ATP involved in group transfer, the more EFFICIENT it is.

Question 9

Why are Redox reactions important to biological systems?

Answer 9

Allow for such processes like aerobic respiration to occur. Allow for work to occur and help the body metabolize
