Enzyme Metabolism Intro

Question 1

What is he difference between Cofactors and Coenzymes?

Answer 1

Cofactors are organic molecules or ions that are required by an enzyme for its activities,(role as a catalyst) which includes Coenymes (enzymes are proteins)

Question 2

Coenzymes are divided into two types:

Answer 2

• Cosubstrate (loosly bound)

- Prosthetic Group (Tighlty Bound)

Question 3

Name 4 Biochemical pathways

Answer 3

• Glycolosis->ATP
• Krebs Cycle(Citric Acid Cycle)->
• Oxidative phosphorylation
• Glucogenesis->synthesis of glucose

Question 4

Apoenzyme

Answer 4

is an inactive form of an enzyme without a cofactor

Question 5

Haloenzyme

Answer 5

Active form of an enzyme (with cofactor)

Question 6

What is AMP

Answer 6

is a structural component of

Question 7

What is a catabolic pathway?

Answer 7

Large molecules are broken down into small ones (Energy is released)breaking down complex molecules

Question 8

What is an anabolic pathway?

Answer 8

energy is required to assemble small molecules into larger ones .
Building complex molecules

Question 9

Why are coenzymes needed?

Answer 9

1. Needed for organisms that cannot biosynthesize precursor molecules
2. Group transfer reagent
   - H+/Molecules

Question 10

What are Oxido-reduction coenzymes?

Answer 10

transfer hydrogens or electrons

Question 11

Transferases definition and example

Answer 11

Coenzyme A is an example of a transferase, which is a group transfer enzyme, that focuses on Acyl group transfers
originates from vitamin B5,thioester bond and is energy rich

Question 12

Name prosthetic examples:

Answer 12

1.CoenzymeA,

2.
