Objects Experiment A: There will be six test tubes are set up‚ which contains one control variable and five different types of substrates: Cyclohexanol‚ (1‚ 4) - Cyclohexandiol‚ (1‚ 2) - Cyclohexanediol‚ Catechol‚ Resourcinol. The darkness of these five test tubes will be the depended variables. Experiment B: There will be eleven test tubes are set up‚ which contains one control variable and ten different types of substrates concentrations : 10%‚ 20%‚ 30%

Part 1 dilutions participated as a trail run to gather around the “full enzyme” that was used for the other parts of the experiment. Part 2 readings were in the time span of 10 minutes and the final results show a spontaneous increase in the first minutes of the absorbance readings. They then showed a steady reading towards the end of timing. The amount of enzyme is decreasing as the dilution occurred. The activity it catalyzes measures the amount of enzyme present in the reaction (Introduction to

PARKINSON’S DISEASE NAME: INSTITUTION: Introduction Parkinson ’s disease is a regarded as a common neurodegenerative condition. The etiology of the disease has not completely been understood‚ but the condition has been associated with a confluence of factors. The first is the loss of a number of neurotransmitters‚ most notably dopamine that produces neurons in the pars compacta of the substantia nigra. It has also been linked to the combined effects of environmental exposures and aging

Dopamine and the related substances norepinephrine (NE) and epinephrine (EPI) comprise a small but important group of neurotransmitters and hormones called catecholamines. * Catecholamine contains two chemical similarities: a core structure of catechol and a nitrogen-containing group called an amine. The catecholamines‚ in turn‚ belong to a wider group of transmitter called either monoamines (transmitters that possess one amine group) or biogenic amines * EPI – adrenergic. NE- noradrenergic

new enzyme formed is called dopamine. Dopamine is then hydroxylated‚ and turns into norepinephrine. Lastly‚ norepinephrine is methylated to form epinephrine. Through the process of chemical synthesis epinephrine can be produced by the reaction of catechol and chloroacetyl chloride. This then reacts with methylamine. This is reduced to a hydroxylic compound. The result of this is epinephrine. Using tartaric acid‚ epinephrine can be separated. I chose to research epinephrine because of the difference

With a variety of new world monkeys‚ the capuchin monkeys have their own characteristics that differentiate them from others. The capuchins are apart of the superfamily of Ceboidea and from there branch out into the family Cebidae. They are mainly distributed in tropical and subtropical regions in Central and South America(). In these tropical areas the habitats that capuchins can be found in range from deep rainforest to dry forest with a height elevation from sea level to 2700 meters high(). Capuchin

Introduction: With the execution of this experiment‚ we began to go deeper into the Cell and Molecular Biology course. The main focus of the experiment would be how the Restriction Endonucleases cleave the strands of DNA. For this experiment‚ pBR322 was the specimen to use. Restriction Endonucleases work by cleaving the sugar phosphate backbone of specific DNA sites. Restriction enzymes that have been isolated from bacteria have a defensive role. This idea is illustrated when an attacking foreign

Drug Abuse inside the Mind and Body Brittney Rojo COMM/156 17 February‚ 2013 Professor Nicholas Delzotto Since 1980‚ the number of drug addictions resulting in death has risen 540 percent. (Florida Institute of Technology Counseling and Psychological Services‚ n.d.). Drug abuse is a process that progresses through patterns of repetitive behavior through rewarding feelings that come with substance use. Often unintentional‚ users see drug experience as a recreational crutch. Although

Neurotransmitters are brain chemicals that transmit information throughout our brain and body. They transmit nerve signals electrically and chemically between neurons. Neurotransmitters can affect mood‚ sleep‚ concentration and weight. The two kinds of neurotransmitters are: inhibitory and excitatory which‚ respectively‚ calm and stimulate the brain. Dopamine is an inhibitory neurotransmitter so when dopamine reaches the receptor sites‚ it blocks the neuron from firing. Dopamine is produced in multiple
