BIOL 1107 Study Guide - Quiz Guide: Median Plane, Iodine Test, Amylase
Document Summary
Lab 21 - animal form and function i: external anatomy: body planes. Frontal - a lengthwise plane, perpendicular to the midsagittal plane that divides the body into dorsal and ventral halves. Transverse - a horizontal plane that divides the body into upper and lower halves. Sagittal - an off- center longitudinal plane creating unequal left and right halves. Midsagittal (median) - a longitudinal plane along the midline that divides the body lengthwise into externally symmetrical right and left halves: orientations. Continues in the duodenum through activity with the enzyme pancreatic amylase. Monitor the activity of the enzyme amylase on starch use the iodine test. I2ki reagent - positive (blue black), negative (yellow: protein breakdown by pepsin. Protein digestion begins in the stomach and continues in the duodenum. Presence or absence of protein can be detected with biuret reagent. Absence retains the original blue color of the reagent. Presence purple: digestion of fats.
