Beta Vulgaris Lab Report

Pages 3
Beta Vulgaris, better known as the beet plant contains a red pigment known as betalain in the vacuole of the cell. If the membrane of a beetroot cell is manipulated, it will burst and betalain will be released. Detergents and soaps can affect the amount of betalain released from the cell depending on the concentration of the detergents in the water because they contain ingredients that break down the fatty membrane of the cell.
In this experiment, the permeability of a beet cell membrane will be tested at different concentrations of soap and detergents. Small samples of the beet will be placed in different concentrations of detergents and soap. A a colorimeter will be used to measure the amount of betalain released from the cell. If the beetroot cell was placed in plain water, the cell would not be disturbed, therefore the cell would not release any pigment. If there is a high concentration of detergents and soap, the membrane will be more disturbed and as a result, it will release more betalain. The higher the concentration of detergents and soaps that the beet cell is in, the more betalain that is released into the water. …show more content…
Soaps generally consist of natural materials and have fewer byproducts. Soaps are also biodegradable and have a minimal negative impact on the environment. Detergents however were initially created in World War II when there was a shortage of oils that was crucial to make soap. As a result, people used synthetic oils to provide soldiers an alternative way to cleanse themselves. Synthetic products were cheaper and eventually, the American society began to use detergents to clean clothes instead of soap. Since detergents are more harsh than soap, they may cause more damage to the cell

EFSA Scientific Report (2009) 231, 1-107 © European Food Safety Authority, 2009 Review of the potential health impact of β-casomorphins and related peptides SUMMARY Proteins are a very diverse family of large organic compounds involved in many important biological processes. Following their enzymatic hydrolysis during food processing or digestion, proteins may release fragments from their primary amino acid sequence. These fragments are called peptides, and many of them are known to be physiologically active. The possible beneficial effects of bioactive peptides have attracted increasing interest in recent years. On the other hand, there are also reports suggesting that some food-derived peptides might adversely affect human health. Among these, β-casomorphin-7 (BCM7), a peptide sequence present in the milk protein β-casein, has been suggested to...

Microbiology Made Ridiculously Simple

...Preface A well-developed knowledge of clinical microbiology is critical for the practicing physician in any medical field. Bacteria, viruses, and protozoans have no respect for the distinction between ophthalmology, pediatrics, trauma surgery, or geriatric medicine. As a physician you will be faced daily with the concepts of microbial disease and antimicrobial therapy. Microbiology is one of the few courses where much of the "minutia" is regularly used by the practicing physician. This book attempts to facilitate the learning of microbiology by presenting the information in a clear and entertaining manner brimming with memory aids. Our approach has been to: 4) Create a conceptual, organized approach to the organisms studied so the student relies less on memory and more on logical pathophysiology. The text has been updated to include current information on rapidly developing topics, such as HIV and AIDS (vaccine efforts and all the new anti-HIV medications), Ebola virus, Hantavirus, E. coli outbreaks, Mad Cow Disease, and brand-new antimicrobial antibiotics. The mnemonics and cartoons in this book do not intend disrespect for any particular patient population or racial or ethnic group but are solely presented as memory devices to assist in the learning of a complex and important medical subject. We welcome suggestions for future editions. 1) Write in a conversational style for rapid assimilation. 2) Include numerous figures serving as "visual memory tools" and summary charts...

...THE NERVOUS SYSTEM  The nervous system allows the animal to quickly detect, communicate and co-ordinate information about its external and internal environment so it can make efficient appropriate responses for survival and/or reproduction. The two major parts of our nervous system are the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is made of the brain and spinal cord.   The cranial nerves, spinal nerves and ganglia make up the PNS. The cranial nerves connect to the brain. The cranial and spinal nerves contain the axons (fibres) of sensory and motor nerve cells.   Nerve cells areas are also known as neurons. Neurons are the basic unit of the nervous system. They carry information or impulses as electrical signals from one place to another in the body. There are 3 types of neurons: Sensory Neurons- Sensory neurons carry electrical signals (impulses) from receptors or sense organs to the CNS. Sensory neurons are also called afferent neurons. The cell body of sensory neurons is outside the CNS in ganglia.   Motor Neurons- Motor Neurons Carry Impulses From The CNS To Effector Organs Motor Neurons Are Also Called Efferent Neurons. The Cell Bodies Of Motor Neurons Are Inside The CNS.   Interneurons- These are also called intermediate, relay, or associative neurons. They carry information between sensory and motor neurons. They are found in the CNS.  TOP The Structure of Neurons A Neuron consists of THREE MAIN PARTS:     A. CELL...
