Summary Introduction

Case summary:

A woman with phenylketonuria (PKU) is pregnant. The fetus is heterozygous and still is not equipped to metabolize phenylalanine that reaches the fetus through mother’s blood.

Characters in case:

Pregnant mother with PKU and her heterozygous fetus.

Adequate information:

The heterozygous fetus is unable to metabolize phenylalanine.

To determine: The consequence of maternal PKU on the fetus, the reason for the fetus to be heterozygous, and advice should be given to the woman with PKU if she wants to have a child.

Given information:

8. Aerobic respiration of a 5 mM solution of tripeptide that is composed of the following three amino acids; alanine, leucine and isoleucine. Alanine breaks down to pyruvate, leucine breaks down to Acetyl-CoA and isoleucine breaks down to succinyl-CoA. Alanine NADH FADH2 OP ATP SLP ATP Total ATP Leucine Isoleucine Totals Show your work using dimensional analysis here: 4
9. Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. fatty acids glycerol 18 carbons 12 carbons 0=
