Chapter 14, Problem 9P
Summary Introduction

To determine: The location of the 14C label in the starting glyceraldehyde 3-phosphate.

Introduction:

Glycolysis is a series of enzyme catalyzed reactions that yield two molecules of the three carbon compound pyruvate along with the free energy which is conserved in the form of NADH and ATP. In the given experiment, 14C -labeled glyceraldehyde was added to the yeast extract. After a short time, fructose 1, 6-bisphosphate labeled with 14C at carbon 3 and at carbon 4 was isolated.

Summary Introduction

To explain: The source of second 14C label in fructose 1, 6-bisphosphate.

Introduction:

In the given experiment, 14C -labeled glyceraldehyde was added to the yeast extract. After a short time, fructose 1, 6-bisphosphate labeled with 14C at carbon 3 and at carbon 4 was isolated.

Draw a tripeptide of your choosing at pH 7. Have the N-terminus on the left and the C-terminus on the right. Then: Draw a triangle around the α-carbons. Draw a box around the R-groups. Circle the atoms capable of hydrogen bonding. Highlight the atoms involved in the formation of the peptide bonds. What type of structure have you drawn? (primary, secondary, tertiary or quaternary protein structure).
2. For the flow of fluid over a flat membrane of length 10cm, determine the length-average mass transfer coefficient. The relevant properties of the system are u=0.01cm²/s, D=5 x 106 cm²/s, and v = 5.0 cm/s.
Background Freezing isn't the only challenge in cryopreservation - thawing can be just as difficult. A microwave oven seems like a nice solution, since it deposits energy quickly and microwaves are non-ionizing radiation (they do not cause DNA mutation). However, water absorbs microwaves more effectively than ice does, meaning that the portion of an organ that has already melted will get warmer at a higher rate than the remaining ice – the opposite of what we want! - The transmission of radiation through a weakly absorbing material such as ice or water can be modeled by Beer's law, which assumes that the rate of absorption at a depth x is proportional to the local radiation intensity I(x) times an absorption coefficient, which is often written as μ or a or just µ). Noting that absorption decreases the intensity, we can write a differential equation a Solving the differential equation with the boundary condition on the surface being gives the relationship For a standard microwave oven…
