In cell biology‚ a mitochondrion (plural mitochondria) is a membrane-enclosed organelle found in most eukaryotic cells.[1] These organelles range from 0.5 to 1.0 micrometer (μm) in diameter. Mitochondria are sometimes described as "cellular power plants" because they generate most of the cell’s supply of adenosine triphosphate (ATP)‚ used as a source of chemical energy.[2] In addition to supplying cellular energy‚ mitochondria are involved in other tasks such as signaling‚ cellular differentiation

The purpose of this lab was to use a spectrophotometer to find the concentrations of glucose in varying samples of Gatorade. The varying executions included changing the temperature of reaction (room temperature instead of 40 degrees centigrade)‚ changing the time for reaction (20 minutes in the water instead of 45 minutes)‚ and changing the amount of enzyme added (0.1mL of enzyme. The results in from this lab gave data points with respect to ferricyanide. Fortunately‚ ferricyancide and glucose have

The Bioamine Theory of Depression In this essay a review of the literature in relation to the Bioamine Hypothesis of Depression will be carried out‚ and an explanation made that shows that the bioamine theory is no longer thought of as being a satisfactory explanation of depression. Also in the is essay the Mental Health Nurses role will be looked at and the implications of such a biological theory has on nursing practise. If such a theory were to be true what treatment would someone with depression

This means‚ if taken orally DMT requires a monoamine oxidase inhibitor‚ also known as a MAOI‚ or the body will render the chemical inactive. DMT is referred to as a‚ “businessman’s lunch‚” because of its quick on set and short lived trip‚ which is probably why it has become popular amongst club goers and

Evaluate the biological treatments of depression. (16 marks) Antidepressants such as monoamine-oxidase inhibitors (MAOIs) and trycyclics (TCAs) are effective in reducing depressive symptoms. Antidepressants have been tested in trials with placebos and have found to be effective in reducing symptoms of severe depression in around 65% to 75% compared with around 33% for placebos – Gitlin 2002. Gitlin carried out a clinical trial testing selective serotonin re-uptake inhibitors (SSRIs) and placebos
