How does caffeine affect the body?

Smatresk--Dean of the College of Science at the University of Texas at Arlington--offers this explanation: Caffeine--the drug that gives coffee and cola its kick--has a number of physiological effects. At the cellular level, caffeine blocks the action of a chemical called phosphodiesterase (PDE). Inside cells, PDE normally breaks down the second chemical messenger cyclic adenosine monophosphate (cAMP). Many hormones and neurotransmitters cannot cross the cell membrane, and so they exert their actions indirectly via such second messengers; when they bind to a receptor on the surface of a cell, it initiates a chemical chain reaction called an enzyme cascade that results in the formation of second messenger chemicals. Historically, cAMP was the first second messenger ever described. Thus, when caffeine stops the breakdown of cAMP, its effects are prolonged, and the response throughout the body is effectively amplified.

How to make a line graph in Excel (Scientific data) How do you cite website material that has no author, no year, and no page numbers? Because the material does not include page numbers, you can include any of the following in the text to cite the quotation (from pp. 170–171 of the Publication Manual): A paragraph number, if provided; alternatively, you could count paragraphs down from the beginning of the document.

How do you cite website material that has no author, no year, and no page numbers?

An overarching heading plus a paragraph number within that section. A short title in quotation marks, in cases in which the heading is too unwieldy to cite in full. Because there is no date and no author, your text citation would include the title (or short title) "n.d. " for no date, and paragraph number (e.g., "Heuristic," n.d., para. 1). The entry in the reference list might look something like this: Heuristic. Writing in Psychology: Experimental Report Writing.

Summary: Written for undergraduate students and new graduate students in psychology (experimental), this handout provides information on writing in psychology and on experimental report and experimental article writing.

Writing in Psychology: Experimental Report Writing

Contributors:Dana Lynn Driscoll, Aleksandra KasztalskaLast Edited: 2013-03-11 09:54:55 Experimental reports (also known as "lab reports") are reports of empirical research conducted by their authors. You should think of an experimental report as a "story" of your research in which you lead your readers through your experiment. As you are telling this story, you are crafting an argument about both the validity and reliability of your research, what your results mean, and how they fit into other previous work. These next two sections provide an overview of the experimental report in APA format. General-specific-general format. APA Lab Report Format.pdf. TS-Bio-Lab-Report-3.pdf. Lab_Reports_for_Biology.pdf.

The Plasma Membrane fluid mosaic model, semi-permeable (selectively permeable), double layer of phospholipids with embedded proteins Jobs of the cell membrane Isolate the cytoplasm from the external environment Regulate the exchange of substances Communicate with other cells Identification Phospholipids (fats) contain a hydrophilic head and a nonpolar hydrophobic tail, which creates a barrier.

The pages here are meant to be used as a lecture supplement for anatomy and physiology students. Many students have told me that these pages have been helpful to them, so I encourage you to go through them and learn from them as well. These web pages were originally written for a partial-distance education course, but that is no longer offered. From this home page, you can link to any topic, listed as a Unit page.
