Can the levels of nitrogen given to the plants during their growth phase induce the synthesis of nitrate reductase by plant tissue?

The first enzyme in the set of plant reduction reactions is nitrate reductase. What factors affect the transcription and translation of nitrate reductase?

Compare and contrast the activity of GLUT-1 and the glucose/Na transporter protein.

1. After several weeks of staining procedures, explain how fixation and staining reveals additional information about a microscopic object.

2. You have discovered a new kind of microbe, never observed before. What kind of questions about this microbe might be answered by light microscopy? What questions would be better addressed by electron microscopy

Please explain and work through the following genetics problem:

• An organization of the data set given below in a table.
• The determination of recombinant classes.
• The determination of the double recombinant class.
• All calculations and determinations of individual map distances.
• A final map with the correct placement of genes relative to one another and their map distances.
• Calculations of the coefficient of coincidence (with actual and expected DCOs) and calculation of interference.

A newborn girl appeared normal at birth, but within 24 hours she developed lethargy, hypothermia, and apnea. The attending physician suspects a metabolic disorder and orders a panel of labs.

Which diagnostic would be the best to distinguish between a urea cycle disorder and a disorder in ​β -oxidation? WHY IS THE OTHER ONES NOT AN OPTION

1. Blood glucose

2. Urinary acids

3. Serum fatty acids

4. Plasma glutamine

A full blood work up was ordered for this female and the data is presented below.

The initial blood ammonia level was elevated at 314 ug/dl (normal range = 17–80) and rapidly rose to 600 ug/dl.

The urine orotic acid level was markedly elevated at 473 umol/L creatinine (nl = 0–3). The plasma citrulline level was normal at 10 uM/L (nl = 12–55).

In this patient where orotic acid levels are elevated, list one urea cycle enzyme that is ​most likely deficient and one urea cycle enzyme that is ​least likely​​ to be impaired. EXPLAIN WHY NOT OTHER ENZYMES

Which of the following did NOT contribute to an increase in antibiotic resistance in bacteria? Question 24 options: A) Prescribing of antibiotics for viral infections B) Addition of antibiotic to common household products, such as hand soap C) Failure by hospitals to sterilize surgical tools D) All of the above contributed to antibiotic resistance in bacteria.

Discuss the Bauhaus movement as a 20^th century phase of European culture. In what ways did world events influence Bauhaus as an aesthetic and philosophical movement.

In RFLP, ladders are electrophoresed_________________.

The product rule in DNA type matching is important since

- it allows the determination of blood type of the suspect

- it allows for the determination of the sex of the suspect

- it allows for a better confirmation of the match between a suspect and the DNA evidence found

- it unequivocally demonstrates the population genetics of the suspect

- it determines the sequence polymorphism for a suspects DNA

a. What is fluid mosaic model of cell membrane and what is its functional importance?

b. Describe the differences between active and passive transport of material across membrane with examples.

1. Some enzymes, require other molecules, co-factors, to become activated and/or to function.

a. In general, describe what type of molecule a co-factor typically is, what it does and the common types of chemical interactions it forms with the enzyme. In your explanation, include the terms: apoenzyme and holoenzyme, and describe how a cofactor affects the enzyme-substrate affinity.

b. Compare/contrast the two main classes of cofactors, and describe an example of each (other than the ones presented in lecture). PS: “describe” means to explain how the cofactor interacts with the enzyme and what the effects are
