The reason why denaturation of proteins makes them better substrates for proteolysis should be determined. Concept Introduction: Proteolysis can be defined as the breakdown of peptides or proteins into amino acids by the action of enzymes. It is classically catalyzed by the proteases that are cellular enzymes. It occurs by intra-molecular digestion. Denaturation of proteins means the degradation of proteins to a simpler level.

Chapter 23, Problem 1P

Interpretation Introduction

Interpretation:

The reason why denaturation of proteins makes them better substrates for proteolysis should be determined.

Concept Introduction:

Proteolysis can be defined as the breakdown of peptides or proteins into amino acids by the action of enzymes. It is classically catalyzed by the proteases that are cellular enzymes. It occurs by intra-molecular digestion. Denaturation of proteins means the degradation of proteins to a simpler level.

Expert Solution & Answer

Answer to Problem 1P

When the proteins become denatured, they are more accessible by the proteolytic enzymes as substrates for the proteolysis process than are natural proteins.

Explanation of Solution

A protein has a 3-dimensional structure that is not accessible to the proteolytic enzymes. It happens because the proteolytic enzymes cannot act on the peptide bond when the proteins become denatured. Denatured proteins are therefore more accessible as substrates for the proteolysis process than are the natural proteins.

How does a voltage-gated sodium channel work? Specifically, how and why does a change in voltage trigger their opening? Please be detailed

When sodium ions enter a neuron during depolarization, they trigger the opening of additional voltage-gated sodium channels nearby, creating a positive feedback loop where the influx of sodium ions further depolarizes the membrane, causing even more sodium channels to open and allowing more sodium ions to enter the cell, thus sustaining the depolarization process until the action potential peaks. But how and why exactly does the influx of sodium ions trigger more sodium channels to let in more sodium? Please explain
