You are working as exercise physiologist for a company and your job includes tests to measure fat oxidation rate (lipid metabolism) during exercise. One individual, who is on a normal diet, did not follow recommendations for fasting and consumed a high fat meal 1-2 hr prior to testing. The fat oxidation response of the individual during prolonged moderate intensity exercise was 30% higher than normal compared to subjects of same age, sex, exercise capacity, and daily diet.

What are possible causes for higher rate of fat oxidation during exercise? Explain the mechanisms involved. Focus on determinants of lipid utilization during exercise

Physical education, exercise science, and sport are defined as one field. In today's society, should they be collectively considered one field or separately as multiple fields? Why? What factors can you use to support your stance?

A single sensory neuron informs the CNS of a very large stimulus using multiple APs in rapid succession. True False

Name three (3) characteristics of red blood cells which make them well suited to carry oxygen to tissues?

1. The three-dimensional shape of a protein determines its function. Briefly explain these terms as they relate to protein shape and provide a supporting example for each: denature, conformational change, genetic mutation. Each example must include a specific protein.

2. Compare and contrast simple diffusion and facilitated diffusion. In other words, how are they similar and how are they different? Provide supporting examples for each.

3. (a) What is the osmolarity of a solution containing 85 mM C6H12O6, 120 mM KCl, and 24 mM CaCl2? Show your calculations. (b) What would happen to human blood cells put in the solution above? Explain.

2. Cytoskeleton of neuron is very important to neuron function. Alzheimer’s disease is an example of central nerve system disease related to cytoskeleton dysfunction. How are proteins of “tau” and “amyloid” related to Alzheimer’s disease (AD)? Please elaborate this question as much as possible.

In about 6 paragraphs explain the actions of different types of hormones in our bodies and how people view hormones in general

How is sensory information coded? That is, how can your CNS distinguish the type of stimulus, the location of the stimulus, and the intensity of the stimulus?

How did the valve influence the experimental results? Is possible, indicate the difference in water displaced( in ml) with the valve versus without the valve. does the valve enhance water flow? Why?
