Would a defect in dynein or in kinesin cause a zebra fish embryo to remain darkly colored after daybreak? Introduction: Kinesin is a class of motor proteins which is found in the eukaryotic cells. It moves along with the microtubule filaments and helps in carrying molecules from center of the cell. It transports molecules from center of the cell to the periphery. Dynein is a class of cytoskeletal motor protein and it moves along with the microtubules in the cells.

To determine:

Would a defect in dynein or in kinesin cause a zebra fish embryo to remain darkly colored after daybreak?

Introduction:

Kinesin is a class of motor proteins which is found in the eukaryotic cells. It moves along with the microtubule filaments and helps in carrying molecules from center of the cell. It transports molecules from center of the cell to the periphery. Dynein is a class of cytoskeletal motor protein and it moves along with the microtubules in the cells.

Expert Solution & Answer

Explanation of Solution

Motor proteins are small accessory proteins which are present in cells along with the microtubules and microfilaments. It helps in the movement of substances within a cell. There are two types of motor proteins; dynein and kinesin.

Kinesin helps in the transportation of cellular material towards the plus end of the microtubules which is located at the periphery of the cell, while dynein carries cellular material towards the minus end of the cell, which is located at the centrosome in the interior of the cell. Its movement is accomplished by the energy driven from ATP.

Melanophores are similar to melanocytes which controls pigmentation in skin. In zebra fish, during night, the melanin granules in the skin of fish embryo are dispersed throughout into the melanophores and make its skin darkly colored. However, in the morning, the melanin pigment granules are aggregated at the center of the cell causing the light color of the embryo. Kinesin helps in the movement of melanophores granules out towards the plus end of the microtubules dispersal during night, while dynein helps in the movement of granules back towards the minus end during aggregation in the day time.

Conclusion

A small defect in dynein causes the melanin granules to remain dispersed as it helps in the aggregation of granules towards the minus end of the microtubule during day time. However, the kinesin helps in dispersion during the night time. This camouflage property helps the zebra fish to prevent their young developing organisms from predators.

If a bacterium using aerobic respiration was to degrade one small protein molecule into 8 molecules of pyruvic acid, how many ATP would that cell make? Assume there is no other carbon source. Units cannot be entered in this style of question but the units of your answer should be in molecules of ATP.

If a bacterium using aerobic respiration was to degrade a 30 mM solution of citric acid, how many ATP would that cell make? Assume no other carbon source is available. Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.

How much ATP will be produced during the following metabolic scenario: Aerobic respiration of a 5mM lipid solution that is made up of one glycerol and an 8-carbon fatty acid and 12-carbon fatty acid. Recall that when glycerol breaks down to Glyceraldehyde-3-phosphate it costs one ATP but your get an extra FADH2. Every two carbons of a fatty acid break down to one acetyl-CoA. (pathways will be provided on the exam) Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.
