Second examination (100 points) Ise this reaction to answer questions 1-2. H2O 02 HNCH-COH CH2 CH2 NADH + H NAD 8.4kcalmol Phenylalanine Tyrosine 1. Phenylketonuria (PKU) is an autosomal recessive genetic trait resulting in lack of the enzyme necessary to metabolize phenylalanine. PKU leads to brain damage, seizures, and mental retardation. A PKU test is done on all newborns and PKU can be managed with a diet low in phenylalanine What type of enzyme is phenylalanine hydroxylase? a) isomerase; b) ligase; c) lyase; d) oxidoreductase; e) transferase. 2. Phenylalanine is a) an amino acid; b) a fatty acid, c) a monosaccharide; d) a nucleoside; e) protein. 3. The products of the light-dependent reaction necessary for plant synthesis of carbohydrates a) ATP and NADPH+H+; b) O2 and water; c) water and light; d) CH12Os and Oz; e) chlorophyll molecules. Six molecules of CO2 made from radioactive carbon atoms (C) and radioactive oxygen atoms (as "c O2) are given to a plant. How many molecules of radioactive molecular oxygen ("O) are given off by the plant? a) 0; b) 2; e) 6; d) 18; e) 36. (o) Which one of the following summary conversions yields the most new ATP molecules under acrobic conditions? a) 3NADH +H 3NAD+3H2O c) glucose- 2 ethyl alcohol + 2CO2 d) 2 pyruvic acid 2 acetyl CoA c) 2 cytochromere +4H 2H2O+ cytochrome Yeast are facultative anaerobes. Assume your friend is trying to make beer at home. He tells you he has a large number of yeast cells but no alcohol. What is the most likely explanation? a) too much sugar; b) not enough sugar; c) too much light; d) too much 02; e) not enough O2.

Explanation / Answer

oxidoreductase

amino acid. Phenylalanine is an -amino acid with the formula C 9H 11NO 2

ATP and NADPH+. The two products of the light-dependent reactions of photosystem are ATP and NADPH.

It will give 6 molecules of radioactive O2. This is because moles of CO2 is equal to the moles of O2 in the photosysthesis reaction.
