John is a sedentary 60-year-old male who wants to lose 15 pounds. His usual diet is moderate in protein, some vegetables like potatoes and carrots, and whole grains and cereals. He’s decided that to lose weight, he’ll cut down on carbohydrates in his diet, and increase the protein content. However, John doesn’t want to give up his Starbuck’s caramel latte in the morning, so the coffee and two boiled eggs are his usual breakfast. His favorite lunch is a cheese burger, sans bun, with two slices of tomato and half of a small order of French fries. For dinner, he usually has a chicken breast with a small side salad. John is losing weight, but he’s now experiencing constipation and severe cramping. Question 1: Analyze John’s current diet and explain how it can affect his GI microbiome and overall GI tract health. Discuss in your answer some dietary components promote the growth of beneficial GI tract bacteria and the benefits these bacteria convey. Support your answer with data, facts, key terminology, specific examples and other information drawn from the textbook and at least one other supplemental sources.

Provide a detailed explanation of the effects of obesity on macronutrient metabolism (carbohydrate, lipid and protein) during pregnancy and the resulting effects on fetal growth and development.

1) Why are quantum dots generally created for biological use having a core-shell design?

2) Design a probe and experiment where you could monitor the endogenous in vivo activity of a particular protease that cleaves the peptide sequence DEVD. Assume this protease is present at extremely low levels in the body.

1) What properties would you consider important for designing a fluorescent probe that could be used in vivo to study an enzyme activity found in blood vessels?

2) What is the difference between an epitope tag and a fusion protein? Describe how you might image dynamics of centrioles in live cells during cell division assuming you use a genetic approach involving creating a fusion protein. Use diagrams and words to explain what proteins you would use to do this and how you would design your experiment.

3) Show two different chemical labeling methods you could use to label high quality antibodies you have obtained from a company by using small organic fluorophores purchased from a chemical supplier. Draw the chemistry occurring on the antibody.

There are techniques in biotechnology that can create genetically engineered babies.

This technology can cure genetic diseases, such as Multiple Sclerosis, Hodgkin’s Disease, Cystic Fibrosis, Alzheimer’s, or Sickle Cell Anemia. However, it can also be used to give cosmetic characteristics or traits that would result in an unfair advantage, such as creating better athletes by giving them incredible strength. Write a 250-word Essay on how this technology should be used in the future. Should limits be placed on what can be done with this technology? How can such regulations be enforced?

OUTLINE

1) How should this technology be used in the future? - To prevent genetic diseases and assist the child in living a healthy life.

2) Should limits be placed on what can be done with this technology? - YES. This technology should not be used for superficial purposes, such as appearance concerns, building better athletes, and selecting the sex of the child.

3)How can such regulations be enforced? - By setting laws that require the procedures to only be used for health concerns and the prevention of genetic diseases.

Which of the following occurs in cellular respiration but NOT in photosynthesis?

oxygen is consumed

water is split

electrons pass through an electron transport chain

protons are pumped across the inner mitochondrial membrane

there is a negative free energy change

redox reactions are aided by enzymes
