List and identify the seven classes of essential nutrients. For each, give at least two major functions it performs in the body and two key food sources. Define subcutaneous far, visceral fat, and percent body fat. Also identify and describe three methods for assessing body weight and body compositions. describing the types of diabetes, preventive […]

A 2-day-old Caucasian boy develops tachypnea and cyanosis with a blood pH of 7.1. A serum bicarbonate (HCO 3) is measured as 12 mM, but the (P O2) and (P CO2) are not yet available. Recall the pK a of 6.1 for carbonic acid (reflecting the HCO 3/CO2 equilibrium in blood) and the fact that […]

What are the roles of the cornea, the iris, the pupil, and the lens in human vision? What is accommodation? Explain how it produces a focused image on the retina. What are the different classes and subclasses of photoreceptros? How do they convert light into neural signals? What are some ways that eyes vary across […]

Term Description Acid Electrons are shared equally between atoms, leaving no charge. Covalent Bond High amount of H+ atoms in water Base Same number of protons but different numbers of neutrons Electrons High pH Hydrophilic Contains no charge. Isotopes Electrons are shared between two atoms. Neutrons Contains a negative charge. Non-polar Electrons are shared unequally […]

The standard free-energy, delta G°’, for a given chemical reaction is positive. However, the reaction proceeds spontaneously in-vivo without energy coupling. Explain this phenomenon using the Gibb’s free energy equation

Determine what type of mutation is described by each of the following scenarios. Note that answers may be used more than once or not at all. Prompt 1DNA polymerase inserts a mismatched base Answer for prompt 1 DNA polymerase inserts a mismatched base Prompt 2two bases are deleted from a gene Answer for prompt 2 […]

Can you design an experiment to determine how the molecules found in milk (lactose, fats, and proteins (whey and curd) respond to freezing temperatures? Make sure to clearly describe your control group, your experimental group, and what you would measure!”

2. You have stock solutions of fully protonated 0.500 M glutamine (pK1 2.2 and pK2 9.1), 0.350 M NaOH, 0.350 M HCl and deionized water. Determine what pH ranges glutamine would be a suitable buffer. Using the stock solutions as needed, describe what you mix and at what volumes to make 500 mL of a […]

I am mostly focused on parts (b) and (d), which I typed out. For (b), I can tell the first pair of graphs is a sequential reaction (when Cysteine is saturated), but it appears ping-pong for the others because the slopes are roughly parallel. I know sequential has to reactants binding (so I guess that […]
