Theory IBO | Using respirometers A respirometer is a device used to measure the rate of respiration of a living organism by measuring its rate of exchange of oxygen and...
Theory IBO | Summary of Energy and Respiration 1 Organisms must do work to stay alive. The energy input necessary for this work is either light, for photosynthesis, or the chemical potent...
Theory Photosynthesis overview Photosynthesis is a series of reactions in which energy transferred as light is transformed to chemical energy. Energy from light is trapped...
Theory Photosynthetic Pigments Photosynthetic pigments are pigments presented in chloroplasts or photosynthetic bacteria. They capture light energy necessary for photos...
Theory The light-dependent reactions, Photophosphorilation Chlorophyll molecules in photosystern I (PSI) and photosystern II (PSII) absorb light energy. The energy excites electrons, raising their en...
Theory Chloroplasts Photosynthesis takes place inside chloroplasts . These are organelles surrounded by 2 membranes, called an envelope . Chloroplasts are fou...
Theory The light-independent reactions (Calvin cycle) The light-independent reactions take place in the stroma of the chloroplast, where the enzyme ribulose bisphosphate carboxylase , usual...
Theory Michaelis Menten Equation Michaelis Menten equation is used to study the kinetics of enzymatic reaction. Usually, the rate of reaction (a.k.a. velocity) is measured a...
