Chapter 23, Problem 4P
Interpretation Introduction

(a)

Interpretation:

The reason for the requirement of ATP hydrolysis by the 26S proteasome should be determined.

Concept introduction:

Proteasome is a composite of proteinases that are involved in the breakdown of specific intracellular proteins. ATP hydrolysis is a catabolic process that helps in releasing the chemical energy from the high-energy phosphoanhydride bonds in ATP. Energy is liberated by splitting these bonds.

Interpretation Introduction

(b)

Interpretation:

The reason for small peptides can be hydrolyzed deprived of the ATP use should be determined.

Concept introduction:

Proteasome is a composite of proteinases that are involved in the breakdown of specific intracellular proteins. ATP hydrolysis is a catabolic process that helps in releasing the chemical energy from the high-energy phosphoanhydride bonds in ATP. Energy is liberated by splitting these bonds.

At a pH equal to the isoelectric point (pl) of alanine, the net charge of alanine is zero. Two structures can be drawn that have a net charge of zero, but the predominant form of alanine at its pl is zwitterionic. CH3 H,N CH3 ** H¸N-C H Zwitterionic H Uncharged OH Select statements that explain why alanine is predominantly zwitterionic at its pl. pk of alanine's amino group is more than its pl. pk of alanine's carboxyl group is more than its pl. PK of alanine's carboxyl group is less than its pl. pk of alanine's amino group is less than its pl. Correct Answer What fraction of alanine is in the completely uncharged form at its pl? 1 in 2.2 × 107 1 in 1.6 × 10² 1 in 4680 1 in 9460
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
