To identify the form of fructose that enters the glycolysis metabolic pathway as an intermediate. Concept introduction: In the glycolysis metabolic pathway, a glucose molecule is converted into two pyruvate molecules. Two ATP molecules and NADH coenzymes are formed along with pyruvate. An intermediate is defined as the transient species that is formed from the reactants in the preceding step and gets consumed in the subsequent steps to generate the products. An intermediate is formed within a multi-step reaction mechanism. In the phosphorylation reaction, the molecule is attached to the phosphoryl group. The transfer of a phosphoryl group ( PO 3 2 − ) is catalyzed by a kinase enzyme. In the glycolysis process, the phosphate group comes from ATP, ADP or some higher energetic phosphate molecules. In the isomerization reaction, a molecule transformed itself to another molecule, having the same number of atoms with a different arrangement. In the cleavage reaction, the covalent bond in the large molecule is cleaved and the molecule is dissociated into two or more fragments.

Interpretation Introduction

Interpretation: To identify the form of fructose that enters the glycolysis metabolic pathway as an intermediate.

Concept introduction: In the glycolysis metabolic pathway, a glucose molecule is converted into two pyruvate molecules. Two ATP molecules and NADH coenzymes are formed along with pyruvate.

An intermediate is defined as the transient species that is formed from the reactants in the preceding step and gets consumed in the subsequent steps to generate the products. An intermediate is formed within a multi-step reaction mechanism.

In the phosphorylation reaction, the molecule is attached to the phosphoryl group. The transfer of a phosphoryl group (PO32−) is catalyzed by a kinase enzyme. In the glycolysis process, the phosphate group comes from ATP, ADP or some higher energetic phosphate molecules.

In the isomerization reaction, a molecule transformed itself to another molecule, having the same number of atoms with a different arrangement.

In the cleavage reaction, the covalent bond in the large molecule is cleaved and the molecule is dissociated into two or more fragments.

Dr. Mendel asked his BIOL 260 class what their height was and what their parent's heights were. He plotted that data in the graph below to determine if height was a heritable trait. A. Is height a heritable trait? If yes, what is the heritability value? (2 pts) B. If the phenotypic variation is 30, what is the variation due to additive alleles?

Experiment: Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp. A=0.624g,102-115° B=0.765g, 80-105° C=1.135g, 77-108 What is the percent yield of A,B, and C.
