Document Summary

Midterm is an hour, mix of mc and short answer maybe fill in the blanks. How drugs effect our body at a cellular level and shows at a physiology level. In depth with receptor pharm and tox page 2 pharm and tox page 3 pharm and tox page 4 pharm and tox page 5 pharm and tox page 6. It is the study of the effects of chemical substances on the function on living systems. Know the chemical structure , if there is side effects. Drugs are either synthetic, obtained by animals or plant, or product of genetic engineering pharm and tox page 7. 3000bc just said here is a potion drink this, could be 100 different chemicals in it. Around 1600 apothecaries, knew a little bit more about the chemicals. Say listen i have a head ache and they would say this route extract will help the head ache.

1. True or False: A postsynaptic potential isexcitatory (EPSP) if the ion involved has a reversal potential(Eion) that is more depolarized than the resting membrane potential(Vm or Vrest), even if that Eion is hyperpolarized to the thresholdfor firing an action potential.

2. An EPSP causes adepolarization of 15 mV on a proximal dendrite. At the same time,an IPSP causes a hyperpolarization of 10 mV in a different proximaldendrite.

Vm is -65 mV, and threshold for firing an action potential is-55 mV.

In this case, will an action potential be generated?

		A. No, because the net effect on the membrane is -60 mV, whichis below threshold.
		B. Yes, because the EPSPs travel faster than IPSPs, so thehillock (trigger zone) will be stimulated to -50 mV, which exceedsthreshold.
		C. Maybe. We don't have enough information to answer this.
		D. It depends on factors like "how much will the gradedpotentials decay before they arrive at the hillock". In short, ifthe axon hillock (trigger zone) is depolarized beyond -55 mV, theanswer is "yes". If not, then "no".

Virtual Lab #1 - http://www.reading.ac.uk/virtualexperiments/ves/preloader-photosynthesis-full.html

Bubbles are given off by the plant through photosynthesis. By measuring the rate at which the bubbles are produced it is possible to tell how fast the plant is photosynthesizing. Read and follow the directions on how to use this lab simulator. Press start and record the bubbles per minute for each of the following light distances.

Then graph your data (be sure to label each axis)!

10. Keep your settings from 9c (25Â°C, light intensity of 20, increased CO2).

a. What were the bubbles per minute at this setting? ______ bpm

b. Now increase the temperature to 40Â°C. What were your bubbles per minute? ______ bpm

c. Based on your data, how does an increase in temperature affect the rate of photosynthesis?

11. Return to your settings from 9c (25Â°C, light intensity of 20, increased CO2).

a. What were the bubbles per minute at this setting? ______ bpm

b. Now decrease the temperature to 10Â°C. What were your bubbles per minute? ______ bpm

c. Based on your data, how does a decrease in temperature affect the rate of photosynthesis.

12. Alter the variables in order to determine which combination leads to the highest rate of photosynthesis. Which combination of settings produced the highest number of bubbles per minute? a. Temperature: ________

b. Light: ________

c. CO2: ________
