Provide 2 or more biological explanations of schizophrenia? 1) Genetic Factors Gottesman: Schizophrenia is more common in the biological relatives of a Schizophrenic‚ the closer the degree of genetic relatedness‚ the greater the risk. If a parent has schizophrenia the chance of child having it is 10% MZ twins have 48% chance risk of developing Schizophrenia if their twin has the disorder‚ whereas DZ twins 17% chance of having Schizophrenia if their twin has the disorder‚ that’s more than

Question: With the aid of specific examples‚ describe the concept of a hierarchy of biological organization. What is meant by the phrase “the whole is greater than the sum of its parts?” Answer: In an attempt to appreciate the world from a biological view of molecules‚ cells‚ and atoms; the study in which these properties build upon each other‚ called emergent properties‚ aid in understanding the human body and other life forms and the functions that nonliving matter contribute that assist

Enzymes are biological molecules‚ or proteins‚ that act as catalysts. Enzymes help complex reactions so that they may occur everywhere in life. For example‚ when you eat meat‚ the proteases work to help break down the peptide bonds that occur among the amino acids. Enzymes usually work to complete one specific job which makes them specific catalysts. They also won’t be found all over the body‚ enzymes are found in neural cells‚ intestinal cells‚ and saliva. Enzymes are among the many organic macromolecules

bung. 7. Take measurement of gas after 2 minutes. 8. Repeat. Investigating the effect of enzyme concentration on the rate of an enzyme-catalysed reaction. James Moore Conclusion: For the conclusion we see that in fact the hypothesis is correct. When independent variable increases so does the dependent variable. As the amount of enzyme concentration increases so will the rate of the enzyme catalysed reaction. In the human body substrate is always available therefore there is only one

relies on a substance for normal functioning”. The various addictions vary but several theories claim to give explanations to the modelling of addiction. Genetic theories‚ exposure theories (both biological and conditioning)‚ and adaptation theories. Biological model - According to this model‚ biological factors within the individual is the main cause for addictive behaviour. Neuro-chemical imbalances or having a genetic predisposition towards addictive behaviour are examples of the model. Therefore

Two biological processes which control our stress response involve the hypothalamus and the autonomic nervous system. When a human is under threat‚ the sympathetic branch of the automatic nervous system becomes active and sends a signal to the adrenal medulla. Similarly‚ when the body is no longer under threat‚ the parasympathetic branch sends the body into a more relaxed state. Therefore‚ the human body will automatically react when the body is under threat or stressed and then help itself go back

Describe two biological therapies for schizophrenia and then evaluate each in terms of effectiveness (8 + 16 marks): One biological therapy is the use of typical anti-psychotic drugs‚ such as Chlorpromazine. The main aim of this drug is to treat schizophrenia by reducing the amount of dopamine in the brain. This is because high levels of dopamine are thought to cause schizophrenia‚ therefore by reducing the amount of dopamine‚ the symptoms of schizophrenia should reduce. Typical anti-psychotic drugs

Conclusion…………………………………………………………………………....…….8 Works Cited ………………………………………………………………………………..9 Properties of Enzymes and Competitive Inhibitors. Abstract: Properties of enzymes were found in this experiment and some other factors‚ which affect enzyme activity. Enzymes are catalyst; they catalyze very specific reactions. Results relating to the active site of specific enzymes played a big role while performing this experiment. The purpose of this experiment was to fin how inhibitors affect

Abstract The main goal of the enzyme kinetics experiment was to see how the phosphatase-catalyzed hydrolysis of p-nitrophenyl produced p-nitrophenol in the presence of phosphate and fluoride ion inhibitors of various concentrations. The calculated Km constant was found to be 0.22 for all reactions. The Vmax values for each inhibition ion were 0.00986 for the phosphate ion and 0.00436 for the fluoride ion. The inhibitor constant‚ Ki‚ was determined to be 0.0967 for the phosphate ion. The inhibitor

TITLE: Enzymes AIM: To investigate the effect of temperature on the enzyme lipase INTRODUCTION: The phenomenon of catalysis makes possible biochemical reactions necessary for all life processes. Catalysis is defined as the acceleration of a chemical reaction by some substance which itself undergoes no permanent chemical change. The catalysts of biochemical reactions are enzymes and are responsible for bringing about almost all of the chemical reactions in living organisms. Without enzymes‚ these
