Essay on Body Temp and Reaction Time - 1848 Words

Can Your Body Tell the Time of Day? (NOTE: If you have thought of a statistics project that you would prefer to tackle instead of the one described below, contact me. I’ll try to make an equivalent project using your particular topic of interest.) Objective: You will measure how body temperature and reaction time vary throughout the course of a day, as well as related questions. In particular, you must address each of the questions below. ï‚ · Question 1: At what time of the day is the body temperature highest? When is it lowest? How much difference is there? Are body temperatures between midnight and noon significantly different than body temperatures between noon and midnight? Question 2: At what time of the day does reaction time peak?†¦show more content†¦Introduction: In order to stay healthy and to function efficiently, living things must coordinate their internal processes with the external world. The most obvious feature of our environment that most creatur es have to respond to is the daily cycle of light and dark. Biological processes that follow this 24-hour cycle, such as our sleep-wake cycle, are said to follow a circadian rhythm. One of the best-known circadian rhythms in humans is the daily change in body temperature. We tend to be at our coolest in the early morning and at our warmest in the late afternoon and early evening. Other circadian rhythms include hormone levels, alertness, muscle strength, and heart rate. The controlling regulator for these cyclic processes within the body is thought to be the hypothalamus, which is in the brain. Figure 1. Overview of circadian cycles in humans. This diagram depicts some of the circadian patterns that occur in humans. Note that the clock is on a 24-hour cycle, so that 3:30 p.m., for example, is noted as 15:30. The hormone melatonin, which is a key regulator of the internal circadian clock, peaks in concentration at 21:00 (9:00 p.m.). (Wikipedia, 2008.) Data Collection Requirements: You need to collect both measurements of temperature and reaction time throughout the day. Variables of interest must include (but are not limited to): age of participant, gender of participant, time of day measurement isShow MoreRelatedMetabolism : A Machine Fueled By Activity And Temp1287 Words   |  6 PagesActivity and Temp. Introduction What is metabolism? Metabolism is all of the chemical reactions involved in maintaining the living state of the cells and the organism. The Major point of this experiment was to see how and if the chemical processes of metabolism could impact body temperature. However first it must be explained what body temperature is actually measuring. When we measure body temp. We are actually measuring the body’s ability to make and give off heat. When our body is hot the bloodRead MoreEnzyme Activity1327 Words   |  6 Pagesthe effect of temperature, pH, and substrate concentration on Enzyme activity? Purpose: Enzymes are proteins that speed up chemical reactions in cells. They break down molecules called substrates. Each enzymes have only one substrate that breaks down. Enzymes are produced in the cells of the body and affect the rate of almost all the chemical reactions which take place in living organisms. The rate of enzymes activity is influenced by temperature, pH, and substrate concentration. The purposeRead MoreIntroduction. Circadian Or Diurnal Rhythms Are Metabolic1646 Words   |  7 PagesCircadian or diurnal rhythms are metabolic or behavioural rhythms, in animals and plants, that occur usually within a 24-hour cycle (Abercrombie et al. 1990). The changes in body temperature over the course of a day (24 hours), or in the case of females, over a month, is one of the most documented human circadian rhythms. Body temperature as well as circadian rhythms in humans is controlled by the hypothalamus, a small region of the brain that forms part of the autonomic nervous system. The hypothalamusRead Moreenzymes1044 Words   |  5 PagesIndependent Variable pH Controlled Variables temperature, amount of substrate (sucrose) present, sucrase + sucrose incubation time Effect of Temperature on Enzyme Activity Dependent Variable amount of product (glucose and fructose) produced Independent Variable temperature Controlled Variables pH, amount of substrate (sucrose) present, sucrase + sucrose incubation time Effect of Substrate Concentration on Enzyme Activity Dependent Variable amount of product (glucose and fructose) produced Read MoreThe Establishment of a Chemical Equation Using the Method of Continuous Variation.1627 Words   |  7 Pagesused per mole of acid.

This test relies on the interaction between components of the immune system called antigens and antibodies. Antibodies are proteins produced by the body to identify and neutralize any foreign substances that may be encountered, such as viruses and bacteria. The substances to which antibodies are produced are known as the antigens as they stimulate an immune response. If antibodies are being detectedRead MoreThe Effect Of Different Temperatures On The Reaction Rates Of Enzymes2033 Words   |  9 PagesTemperatures on the Reaction Rates of Enzymes B. Introduction / Background Enzymes are proteins that are in every living organism. Cells need them to survive and to function. Enzymes are catalysts that help to speed up the rate of reactions that otherwise would take longer periods of time to occur. However they do not change during the reaction. A chain of amino acids forms them. There are over a hundred different enzymes in the human body. Each enzyme is responsible for a certain reaction that occursRead MoreInvestigating The Relationship Between Temperature And The Rate Of Lipase1933 Words   |  8 Pagesto find the temperature at which the lipase will be denatured. Introduction: Enzymes are proteins that act as a catalyst to speed up chemical reactions. A catalyst is a substance that increases the rate of chemical reaction but is not consumed or changed by the reaction. A catalyst reduces the activation energy needed to initiate and sustain the reaction. Enzymes molecules have a small region that is functional, known as an active site. Substrate molecules are held within the active site by temporaryRead MoreProduction of Acetone1934 Words   |  8 Pagesoxidation of Propene (Wacker-Hoechst). The process is analogous to the oxidation of ethylene to acetaldehyde by theWacker process. The catalyst solution typically contains 0.045M Palladium (II) chloride, 1.8M Copper (II) Chloride, and acetic acid. The reaction usually is carried out in two alternating stages. In the first stage, air is used to oxidize the metal ions to the +2 oxidation state. In the second, air is removed and propene added. Palladium (II) oxidizes propene, and the resulting Palladium (I)
