Question
Chapter 33, Problem 14P
Interpretation Introduction
Interpretation:
The mechanism of the reaction between opsin and 11-cis retinal should be determined.
Concept introduction:
The retinal is a conjugate chromophore of the human eye. The retinal in normal conditions is present in the 11-cis-retinal configuration. In the presence of light, it is straightened and converted into the all-trans-retinal configuration. This opsin pushes the retina that triggers chemical signaling cascade andresults in the perception of the light by the brain.

- B- Vitamins are converted readily into important metabolic cofactors. Deficiency in any one of them has serious side effects. a. The disease beriberi results from a vitamin B 1 (Thiamine) deficiency and is characterized by cardiac and neurological symptoms. One key diagnostic for this disease is an increased level of pyruvate and α-ketoglutarate in the bloodstream. How does this vitamin deficiency lead to increased serumlevels of these factors? b.

Draw out the structures and names of all compounds neatly by hand and the pathways responsible for metabolizing them. Some examples are: Glycolysis/gluconeogenesis, PPP, Glycogenesis/glycogenolysis, Krebs, ETC, selectamino acid pathways (Ala, Glu, Asp) Lipogenesis/lipolysis. Citrate/MAS/glycerol phosphate shuttlesystems, and the Cori/Glc-Ala cycles. Rules:-Draw both a mitochondrial area of metabolism and a cytoplasmic area of metabolism.-Draw the liver and its roles in glucose recycling (Cori cycle/Glc-Alanine recycling)-Avoid drawing the same molecule twice (except for separate mitochondrial/cytoplasmic populations. i.e. Design the PPP/Glycolysis so that GAP is only drawn once)-Label Carbon 4 of glucose and highlight where you would expect to find it in EVERY compound in whichit is present.-Have one or two locations for NADH/NADPH/ATP/GTP/CoQH2 – many arrows will come to/from thesespots.arrow_forward
