The following kinetic data were obtained for an enzyme in the absence and in the presence of an inhibitor at a 5 mM concentration. You can assume that the same amount of enzyme was present in each assay, [ET]

Determine the Km and Vmax values for the enzyme in the presence and presence of the inhibitor. (Show your graphical results!) Report Km or Vmax values in mM or mM/min as appropriate, and indicate which type of inhibition is demonstrated by the inhibitor? You MUST explain your reasoning
Trace a drop of blood from tissue cells of the left knee to capillaries of the right arm. Be sure to stop at the lungs along the way! Keep track of the left and right sides of the heart, and mention all the valves through which the blood travels.
Two closely related species of wolf spiders live together in northern California. However, meadow wolf spiders are only observed in meadows and forest wolf spiders are only observed in the forest. Both species are found near forest-meadow edges.
A 20-year-old athlete, Ms. G., had arthroscopic knee surgery. Over the next week she noticed mild swelling, increasing pain, and a small amount of redness at the incision site.
Discuss how does the toxicity of microbial agents affect the human body and how efficient are synthetic agents and how are they used in medicine?
Determine which of the following statements is accurate regarding the evolution of drug resistance in a virus?
When chromatin from any eukaryote is digested with micrococcal nuclease and fractionated using electrophoresis, DNA fragments of approximately two hundred base pairs in length are observed.
What is the frequency of heterozygotes (Aa) in a population in which the frequency of all dominant phenotypes is 0.25 and the population is in H-W equilibrium?
What effect do you think EBV would have on B cell function. What phenotypes would you expect in the F2, and in what actual numbers (not ratios) will you expect to find out them.
A biologist was testing E. coli for thymidine requirement. She found a thy- point mutant and wanted to study reversion to thy+. She grew 20 cultures of the thy- mutant strain and plated them onto 20 plates that contained media
Think about the two linked traits in a population in which half of the individuals are double heterozygotes with genotype AB/ab and the other half are double homozygotes.
What would be the biological advantage for organisms/cells that have alternative energy pathways such as fermentation?
A is recessive and confers a black coat, A is dominant to a and confers an agouti coat, and A Y is dominant to both and confers a yellow coat.
