Chapter 5, Problem 13Q
Summary Introduction

To explain: How do the white sectors arise in the second colony of yeast cells when the yeast Ade2 genes are not expressed.

Introduction: The yeast Ade2 encodes one of the enzymes that required for the adenine biosynthesis. The gene expression is repressed when adenine is present while it is slightly increased under conditions of the amino acid starvation. When the gene is expressed, the yeast colony will be in white and when the gene is not expressed, the colony will have a red pigmentation.

Summary Introduction

To explain: How propagation of the transcriptional state of the Ade2 gene occurs from mother to daughter cells.

Introduction: The yeast Ade2 encodes one of the enzymes that required for the adenine biosynthesis. The gene expression is repressed when adenine is present while it is slightly increased under conditions of the amino acid starvation. When the gene is expressed, the yeast colony will be in white and when the gene is not expressed, the colony will have a red pigmentation.

If a bacterium using aerobic respiration was to degrade one small protein molecule into 8 molecules of pyruvic acid, how many ATP would that cell make? Assume there is no other carbon source.   Units cannot be entered in this style of question but the units of your answer should be in molecules of ATP.
If a bacterium using aerobic respiration was to degrade a 30 mM solution of citric acid, how many ATP would that cell make?  Assume no other carbon source is available.  Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.
How much ATP will be produced during the following metabolic scenario: Aerobic respiration of a 5mM lipid solution that is made up of one glycerol and an 8-carbon fatty acid and 12-carbon fatty acid. Recall that when glycerol breaks down to Glyceraldehyde-3-phosphate it costs one ATP but your get an extra FADH2. Every two carbons of a fatty acid break down to one acetyl-CoA. (pathways will be provided on the exam) Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.
