Chapter 17, Problem 40P
Interpretation Introduction

(a)

Interpretation:

The amount of O2 absorbed by complete oxidation of added citrate is to be calculated.

Concept introduction:

The activity of the citric acid cycle can be observed by accounting the amount of O2. H. Krebs conducts the experiment on pigeon-breast muscle to investigate that the rate of citric acid cycle grows with the increased rate of O2 consumption.

The citric acid cycle is the third step of the biochemical energy production process. The cycle consists of the reactions from which the acetyl part of acetyl CoA is oxidized to form carbon dioxide and CoA-SH.

Interpretation Introduction

(b)

Interpretation:

On the basis of the result in part (a), consumption of oxygen in the presence of citrate is to be explained.

Concept introduction:

The activity of citric acid cycle can be observed by accounting the amount of O2. H. Krebs conducts the experiment on pigeon-breast muscle to investigate that rate of citric acid cycle increases with the increased rate of O2 consumption.

The balanced reaction of complete oxidation of citrate is,

C6H8O7+4.5O26CO2+4H2O

Macmillan Learning Cholesterol synthesis begins with the formation of mevalonate from acetyl CoA. This process activates mevalonate and converts it to isopentenyl pyrophosphate. Identify the atoms in mevalonate and isopentenyl pyrophosphate that will be labeled from acetyl CoA labeled with 14C in the carbonyl carbon. Place 14C atoms and C atoms to denote which carbon atoms are labeled and which are not labeled. H₂C COA 14C-labeled acetyl-CoA HHH [c] H H OH 014C - OH H HH H Mevalonate CH3 H H 14C H Η H H Incorrect Answer of o -P-O-P-0- Isopentenyl pyrophosphate с Answer Bank 14C
