Interpretation Introduction

(a) Interpretation:

The reason that the glucose consumption must increase in the hypoxic tissues to provide the same amount of ATP that could be produced from glucose in normoxic tissues.

Concept introduction:

Hypoxia can be defined as the medical condition when the tissues of the affected person are starved of the oxygen. The hypoxia can be of four different types, namely the hypoxemic type, anemic type, stagnant type, and the histotoxic type. In the extreme cases, when no oxygen is present in the body tissues, it is known as anoxia.

Interpretation Introduction

(b) Interpretation:

The process by which the increase in the LDH expression will increase the glycolysis rate.

Concept introduction:

The LDH is known as the lactate dehydrogenase. This enzyme is present in almost all the cells of the body of all the living organisms. This enzyme converts the sugars consumed into energy through the process of glycolysis.

Interpretation Introduction

(c) Interpretation:

The reason that the increase in the PDK expression leads to a decreased rate of mitochondria respiration.

Concept introduction:

PDK, or the pyruvate dehydrogenase kinase is an enzyme, which is used to inactivate the pyruvate dehydrogenase enzyme. This inactivation is done by this enzyme by phosphorylating the pyruvate dehydrogenase using the ATP.

9) Below, there is a representation of an SDS-PAGE gel. Assuming the samples in the MW standard have masses of: 66 kDa, 45 kDa, 36 kDa, 29 kDa, 24 kDa, 20.1 kDa, and 14.2 kDa, a) Figure 4: indicate where each of the measurements were taken and label as in II.6. figure 2 above. b) As in II.7. Table 1 above create Table 2 using the data below. Determine the r.f. values for the MW standards, plot the relative mobility versus the log of the mass for the standards, and use the best fit straight line to determine the molecular weights of the proteins in the whey, peak 1, and peak 2 lanes. (5 pts—this will be scaled up appropriately if your gel did not develop properly) dye MW Whey Peak 1 Peak 2
