We classify foods into three groups based on their chemical compositions: Carbohydrates, Proteins, and Fats. The digestive and absorptive process differs among these groups due to their chemical structures.

For each of these macromolecules:

1) Come up with an example of each -- what's your representative food item of carbohydrate, protein, and fat.

2) Identify their chemical structures for monomer unit, and the macromolecule polymer.  

3) Determine the digestive reaction that splits the macromolecule into monomers: starch into glucose units; proteins into amino acids; and TAGs into free fatty-acids.

4) identify the digestive enzyme that catalyzes each of these reactions.

Explore the relationship between the human body systems, (musculoskeletal, GI, metabolic, cardiovascular and respiratory) and the flight environment.

Mirror Neurons and Behavior

Research scientists postulate that we imagine ourselves acting out or mirroring movements that we see. This ability seems to be genetic or hardwired since infants can imitate the movements of others. It is possible that mirroring actions is adaptive and may play a role in learning how to do things, and it may facilitate social interactions. More interesting than the actions is the thought that we may have special neurons in our brains that help facilitate imitation. These neurons have been named mirror neurons, and they can be found not only in human beings but also in nonhuman animals.

Answer the following questions:

• Mirror neurons have a distinctive shape and a specific location in the brain. What are the morphology (shape) and location of mirror neurons? Does their location seem to make sense, given that the neurons are thought to play a role in imitation?
• Some nonhuman animals have mirror neurons in their brains. Which other species have mirror neurons? Are these animals more social than animals that do not seem to have mirror neurons?
• When there is a relatively new discovery in the brain, that discovery is often used to explain current diseases and disorders. What are the applied research trends for mirror neurons in the scientific literature? Are there any particular disorders that are being connected to mirror neurons? What is it about these disorders that make people connect them to mirror neurons?

In this laboratory experiment, you wanted to see the effect of Amylase with starch. So you performed the following:

In tube 1 - Combine equal volume of Amylase with Starch solution

In tube 2 - Combine Amylase with water

In tube 3 - Combine water with Starch solution

Let all three tubes sit in a 37C waterbath for 20 minutes. After the 20 minutes incubation was over, then you would test for the presence of starch. In the meantime, what would you predict? Based on what you know about enzymatic digestion, what do you expect here in these tubes? After the incubation period we added Iodine solutions to each tube to test for starch. Here are the results:

In tube 1 - white cloudy solution

In tube 2 - Yellowish solution

In tube 3 - Dark red solution

Explain this result, what happened in each tube? Why is adding iodine important to detect the presence of starch?

2. In order for an effector to respond to a command via either of the endocrine or nervous system, it must be able to respond to a chemical (hormone or neurotransmitter). Explain how the effector is able to respond to these chemical signals (i.e. what must it have either in its membrane or inside its cells). Describe how this process of intercellular communication exemplifies the relationship between structure and function.
