Latin Rigor Mortis Research Paper

Decent Essays

In Latin rigor means “stiffness” and mortis “of dead”, rigor mortis is one of the recognizable signs of death. Stiffening of the muscles is caused by chemical changes in the muscles after death, causing the limbs of the corpse to stiffen after death. This chemical change occurs with the absence of oxygen that is used to make ATP. With this loss of ATP the muscle is unable to relax. The muscle tissue is eventually broken down by enzymes during decomposition. 1. On Friday evening, Jack was spending many hours in the lab conducting experiments. At 11:00 pm, Jennifer, Jack’s wife, tries to surprise him with brownies when she finds the lab dark and Jack and Christie in the tissue culture room. Jennifer pushes Jack which caused him to hit his head on the chemical hood, falling limp. Christie then throws a clear liquid in Jennifer’s face and runs out. From 11:15pm Friday night to 8 am Monday morning it is assumed that jack remained unconscious and as did Jennifer. At 8am Monday morning, Dr. Grisholm found jack and Jennifer dead and called 911. Results then showed that Jack had died approximately five hours before being discovered while Jennifer died approximately thirty hours before being discovered. …show more content…

In a living organism only two ATP can be produced when there is no oxygen available, providing little energy. 3.A. During cellular respiration Glycolysis uses two ATP and produces four ATP per glucose molecule. 3.B. The set of reactions in Glycolysis occur in the Cytoplasm of the cell. 3.C. Oxidative Phosphorylation produces the most ATP during cellular respiration. This occurs when there is a transfer of electrons from NADH or FADH2 to O2 by a series of electron carriers. 3.D. The Kreb’s cycle produces the most NADH, making three per turn which makes six per glucose molecule. 3.E. NADH and FADH2 are the molecules needed to produce ATP by oxidative
