Starting with a fatty acid located in the cytosol of the cell, explain “mechanistically” how an iron deficiency may result in reduced acetyl CoA production from beta oxidation of palmitic acid

compare and contrast the mucosa's between the esophagus and small intestine

pick two of the nervous system pathologies to discuss from the list below.  

For each selected pathology, you should provide the following information: an explanation of the underlying functional or structural deficit present in the condition, predicted deficits based on your knowledge of the normal function and structure of the nervous system (these are educated guesses based on your understanding of nervous system function), and an explanation of at least three signs/symptoms that are seen with this condition (based on sources found during research you have conducted into the chosen conditions). Your discussion MUST include an explanation describing how the deficit produces the observable signs/symptoms AND a statement describing how your chosen conditions affect homeostasis within the body.

Choose two of the following nervous system pathologies to discuss:

Parkinson’s disease

Tay-Sachs disease

Multiple sclerosis

Polio

Hydrocephalus

Guillain-Barré syndrome

Bell’s palsy

State the important distinction between the terms 'serving size' and 'portion'. why do you think that portion sizes of many foods have generally gone up for many people? What might be at least one reason (that might even sound fairly logical) that foods with higher energy densities, and sometimes correspondingly lower nutrient densities, are eaten with greater frequency in many people's diets? .

. If the curve for sufficiency of intake of a given nutrient were narrower (tighter) and the distance between the UL and both the RDA and EAR thus less, how would this impact an individual's approach to attaining an adequate, but not excess, amount of such nutrient?

• Compare and contrast the structure, mechanical properties, and functions of arteries, arterioles, capillaries, venules, and veins in the cardiovascular system.

Imagine that you are part of a research team that specializes in diagnosing disorders associated with malfunctioning cellular organelles and structures.Medical doctors consult your group to help diagnose particularly difficult cases.  Read the patient history, physical examination and lab results to provide a cellular explanation for the case below. In the answer box type the tell the malfunctioning organelle (4 points) AND Rationale for Diagnosis (6 points) (explanation of how history, physical examination and laboratory results suggest diagnosis). Be sure to give all details as rationale counts majority of points.

Patient History:    

• 2-day old male, Low birth-weight (4pds. 5 ounces), Difficulty suckling/swallowing, Seizures, Gastrointestinal bleeding

Physical Examination

• Enlarged liver, Low muscle tone/inability to move, Glaucoma, Facial deformities, Impaired hearing
• Jaundiced skin

Laboratory Results

• High levels of hydrogen peroxide in cells
• High levels of fats and amino acids in cells

Patricia Jones, age 50 years, was diagnosed with idiopathic pulmonary fibrosis (IPF) two years ago. IPF is a chronic, progressive lung disease with no cure. It results in fibrotic scarring and thickening of lungs tissue, impairing oxygen delivery. Despite her diagnosis, patricia continues to work full time at her job, taking the commuter train daily. However, over the past few weeks the demands of activities of daily living have become increasingly difficult. She complains of being tired, persistent dry cough, and extreme shortness of breath when climbing a flight of stairs. She had to take a medical leave from her job. The following information was obtained at her recent physical examination.

FEV₁ = volume of air expired in the first second of forced expiration; FVC, forced vital capacity

After these results were obtained at rest, Sue was asked to exercise on a stair climber. After only 2 minutes, she became extremely fatigued and had to discontinue the test. The arterial blood gas measurements were repeated, with the following results.

1. Idiopathic pulmonary fibrosis is a restrictive pulmonary disease. Define lung compliance and explain how lung fibrosis affects lung compliance. Use this information to explain Patricia's decreased total lung capacity, decreased functional residual capacity (FRC), and decreased residual volume at rest.
