Topic 8. Diagram of Exothermic reaction. Competitive Inhibition. Non-Competitive Inhibition. For example, ethanol has been used to act as a competitive inhibitor for antifreeze poisoning. Fomepizole, which is an inhibitor of alcohol dehydrogenase, has also been used for antifreeze poisoning. The main ingredient in antifreeze is called ethylene glycol.
Catalase is an enzyme found in the cells of many tissues of living organisms. It speeds up a reaction that breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances--water and oxygen.
If the cells did not break down the hydrogen peroxide, they would be poisoned and die. In this lab, you will study the catalase found in liver cells.
The following data has been recorded from the breakdown of hydrogen peroxide by beef liver over a 10 minute time period. Please fill in the following table and calculate the rate of reaction at each time interval. Please show one sample calculation for the rate of mass decrease over time.
Please graph your change in mass over your change in time to show the rate write in the proper labels on the axis, including units. Calculate the overall rate of reaction for the second time period.
What do you notice as the time increases? Why do you think this is the case? Guidance: Enzyme inhibition should be studied using one specific example for competitive and non-competitive inhibition Theory of Knowledge: Many metabolic pathways have been described following a series of carefully controlled and repeated experiments.
IB Biology - Curriculum Notes. Diagram of the Light Dependent Reaction. This creates two molecules called triose phosphate TP. To what extent is the creation of an elegant protocol similar to the creation of a work of art? An electronic version of the leaf that creates oxygen and hydrogen from water and sunlight has already been invented and will be developed for use in the next decade. After the electron carriers are reduced they transport their electrons and hydrogens to the ETC, where the opposite reaction occurs oxidation.
Diagram Krebs Cycle. Electron Transport Chain and Chemiosmosis. Diagram ETC. Role of Oxygen. Metabolism — the chemical reactions that occur in organisms in order for them to maintain life, such as the synthesis of ATP during cellular respiration.A population is a group of organisms of the same species who live in the same area at the same time. A community is formed by populations of different species living together and interacting with each other.

DP Biology Guide. IB Command Terms. Year 1 Review. Essential idea : Cell respiration supplies energy for the functions of life. The energy is held in the bonds between atoms, in particular the high energy bond that joins the second and third phosphates. ATP is the energy currency of the cell.
Hence the efficiency of respiration is measured by the yield of ATP. U1 Cell respiration is the controlled release of energy from organic compounds to produce ATP. U2 ATP from cell respiration is immediately available as a source of energy in the cell.International Baccalaureate IB. Oh, IB Biology.
