M3. Allosteric Enzyme & Feedback Control

Question 1

• Quaternary Structure (2 or more protein chains)
• 2 kinds of binding sites (for substances and for regulators)

Answer 1

Allosteric enzyme

Question 2

1. Substrate?
2. Regulatory?

Answer 2

1. Active site
2. Allosteric site

Question 3

Substance that bind at the regulatory sites of allosteric enzymes

Answer 3

Regulators

Question 4

2 types of Regulators:

Answer 4

1. positive regulator
2. negative regulator

Question 5

• increase enzyme activity
• active site changes to readily accept substrate

Answer 5

positive regulator

Question 6

• decrease enzyme activity
• active site changes such that substrate is less readily accepted

hindi pa ready sa committment, beh HAHAHA

Answer 6

negative regulator

Question 7

process of activation or inhibition of the first reaction is controlled by a product of reaction sequence

Answer 7

feedback control
