the term given to the movement of air in and out of the lungs; the rate of pulmonary ventilation is defined as the tidal volume multiplied by the number of breaths taken per minute. Tidal volume is the volume of air breathed in or out during one cycle of quiet breathing. There are a few different factors that can affect the pulmonary ventilation rate but the most common and often most noticeable variation in pulmonary variation rate occurs during exercise. During normal quiet respiration‚ the average

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

__________________________ Lab Partner: _____________________________________________________________________ Investigating Factors that Affect the Rate of Enzyme Activity See Textbook Pg 61. Enzymes are very large complex organic molecules that are synthesized by the cell to perform specific functions. These biological catalysts are important because they speed up the rate of the reaction that would otherwise be too slow to support life. Catalase is an enzyme present in the cells of plants‚ animals and aerobic

Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC‚ which is the body temperature‚ where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working. Introduction:Enzymes are

Thus‚ I decided to test my theory by adapting a class beetroot experiment to my investigation. The aim of this experiment is to investigate the effect of alcohol concentration on a biotic cell membrane. The human body cannot live long with damaged cells because they are the building blocks of life. Cell membranes are phospholipid bilayers meaning they are
