Question
Chapter 17.1, Problem 1CC
Summary Introduction
To determine: The disorder alkaptonuria is dominant or recessive. Garrod (1902) suggested that this condition is expressed when the faulty gene alleles are inherited from both the parents.
Concept introduction:
Alkaptonuria occurs due to the deficiency of the enzyme homogentisate 1, 2- dioxygenase. Thus, the body is unable to breakdown tyrosine and phenylalanine amino acids causing dark urine. In a research article by Garrod (1902) about alkaptonuria, he suggested that this disorder is caused when the abnormal allele is inherited from both the parents.

What are the steps for an enzyme to create a product in order:
1. The energy of activation is lowered so the reaction can happen quicker.
2. Substrate attaches to the active site.
3. The product is created and released from the active site.
4. The energy of activation is lowered so the reaction can happen slower.
5. A specific substrate attaches to the active site.

Cells sense internal amino acid levels to couple their metabolic state with their gene expres- sion programs. One key regulatory switch that amino acid levels control is expression of the genes required for ribosome biogenesis – all the proteins and RNA molecules that required to generate the small and large ribosomal subunits. Ribosome biogenesis is one of the most resource-intensive pro- cesses in proliferating cells. In order to couple ri- bosome biogenesis – which entails high level syn- thesis of hundreds of proteins – with the availabil- ity of amino acid precursors required to make those proteins, cells evolved a signaling network that converges on a key protein complex in the cell known as MTOR complex 1 (MTORC1). The net result of the signaling network shown in the diagram is that mTORC1 is ultimately activated by the presence of leucine and arginine in the cell (the blunt arrows represent inhibitory interactions; the details are not important here). When MTORC1 is active,…arrow_forward
