Activity 1: Direct Heart Stimulation 1. Did you see any change in the trace? No change in the trace 2. Why or why not? This is because it needs more simulation 3. Did you see any change in the trace? I did see a change in the trace 4. Why or why not? There is double stimulation 5. Describe the change you see in the trace. How does it differ from the baseline trace? The trace increased from the baseline trace 6. What effect do the repeated stimuli have on the heartbeat trace

voltage at which you first saw an action potential? 3.0 V 3. How does this tracing compare to the one that was generated at the threshold voltage? The tracing travel in the same fashion but the tracing were different with an increase threshold voltage 4. What reason can you give for the change? Increase voltage 5. Record this maximal voltage here: 6.0 V Activity 2: Mechanical Stimulation 1. When the glass rod is touching the nerve‚ what do you see on the oscilloscope screen? The nerve’s action

( Check Nutrition Unit 21) Define metabolism and describe the two forms; Anabolism and Catabolism and give examples of each? Metabolism: Every time food is swallowed‚ the body works hard to process the nutrients that have been consumed. Long after the food is digested‚ the nutrients the body has now eaten become the building blocks and the fuel of the body to keep it going. The body gets the energy it needs from food‚ and this is called metabolism. Metabolism is a collection of chemical reactions

Fischer Lab Time/Date: 7:00 PM/Wednesday Activity 1 Metabolism and Thyroid Hormone Part 1 1 Which rat had the fastest basal metabolic rate (BMR)? The normal rat had the faster basal metabolic rate‚ because it was not missing its pituitary gland or its thyroid gland. 2 Why did the metabolic rates differ between the normal rat and the surgically altered rats? How well did the results compare with your prediction

does this change correlate to changes in the nerve? There was little change in effect of increasing the voltage. The action potential increased slightly. There was a small increase in the repolarization and a slightly lower resting potential. 4. How did the action potential generated with the unheated rod compare to that generated with the heated rod? The action potential generated with the unheated rod was similar to that generated with the heated rod. The heated rod made a slightly larger

area of LOW to High solute concentration. 3. Because water moves toward the HIGH concentration of solutes. 4. We know the pressure will increase in the albumin beaker because it is more impermeable than glucose. The pressure in the beaker containing the albumin increased despite the increased concentration of glucose because albumin has a much greater molecular weight. Activity 4 1. Increasing the size of an opening allows more space for movement. For example‚ the more you open the nozzle

Induced Fit Model (Hudon-Miller‚ Enzymes‚ 2013) Why Does Aldolase B Deficiency Lead to HFI? • Understanding what happens to Glucose and Fructose in the liver is the first step. • Glucose enters the liver cell and Glucokinase is in the cytoplasm and adds a Phosphate (Pi) to make G-6-P to keep the glucose in the liver cell‚ which then becomes G-1-P and can be

Metabolism “Metabolism is the set of chemical reactions that happen in living organisms to maintain life. These processes allow organisms to grow and reproduce‚ maintain their structures‚ and respond to their environments” (Metabolism). Metabolism breaks down the food that we eat‚ transforming it into energy for our bodies. Metabolism is broken down into two categories Anabolism and Catabolism‚ which help aid in the chemical reaction process. Specific proteins in the body control the chemical
