Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine

The effect is named after John Ridley Stroop‚ who published the effect in English in 1935 in an article entitled Studies of interference in serial verbal reactions that includes three different experiments.[1] However‚ the effect was first published in 1929 in German‚ and its roots can be followed back to works of James McKeen Cattell and Wilhelm Wundt in the nineteenth century.[2][3][4] In his experiments‚ J. R. Stroop administered several variations of the same test for which three different

Discussion and Conclusions Many obstacles to my potential strategy are worth overcoming. Since the brand new policy is to add extra taxes on smoking and fining the smoking companies for their actions‚ then one is able to make sure that people comply or go out of business.

An investigation to see how much oxygen is given off when different concentrations of catalase are added with hydrogen peroxide. Aim: To see if changing the concentration of catalase (found in celery) with hydrogen peroxide affects the amount of oxygen given of. Background Information: (Hydrogen peroxide - H2O2 1/2O2+H2O) Enzymes: Hundreds of chemical reactions happen simultaneously inside living cells and it’s the job of enzymes to control and regulate the various metabolic

Part B: Practical Report The Effect of Temperature on Enzyme Activity Aim: To investigate how temperature effects the enzyme catalase. Hypothesis: If the temperature of water is increased then the enzyme will react quicker to form oxygen and water‚ when compared to cold water. Purpose: To design and conduct a plan of a practical about the effects of temperature on enzymatic activity with a partner. Introduction: An enzyme is a protein‚ which speeds up a specific chemical reaction without altering

Action potential to occur in a neuron. This will be achieved by firstly‚ defining the purpose of neurons in the body along with a description of the components within a neuron and how they enable information to be passed through the cell membrane and on to other neurons. Secondly‚ the resting potential of a neuron will be explored with relation to the concept of selective permeability and the purpose of the Sodium - Potassium pump. Thirdly‚ the molecular basis of the Action Potential will be
