Aerobic cellular respiration and oxygenic photosynthesis are two cellular processes that have evolved in similar ways. Cellular respiration is responsible for the process of ATP‚ meanwhile oxygenic photosynthesis is the process of turning light energy into food. It is evident that both of these processes have their own reactants‚ products‚ and biochemical pathways. Both of these processes have evolved from their primitive original state‚ but it is important to understand that oxygenic photosynthesis

The Rate of Diffusion in Different Temperatures Purpose: To see if the temperature of a solution will change the rate blue diffuses in it. This will be tested by timing how long it takes dye to diffuse in warm water‚ cold water‚ and room temperature water. Hypothesis: I think that the dye will diffuse at a faster rate in the warm water than in the cold water. I believe that the room temperature water will have the dye diffuse faster than the cold water but slower than the warm water. Variable:

313 Introduction The aim of this experiment is to explore the factors which affect the movement of materials in and out of the cells. The dark red or purple colour of Beetroots is caused by a pigment called betalain that is found within the vacuole of the beetroot cells. The pigment remains intact within the cell if the cells are not “stressed” by the external environment. In this exploration‚ two factors that affect the movement of the betalain out of the beetroot cells will be explored – surface

Temperature and enzyme activity Aim: To determine the effect of which the temperature of the enzyme has on the rate of the enzyme catalysed reaction. Hypothesis: The rate of reaction of an enzyme catalysed reaction will increase as the temperature of the enzyme approaches the optimum temperature. Surpassing the optimum temperature will result in a drop in enzyme activity. Materials: 6% hydrogen peroxide Liver suspension 10 test tubes 4 beakers Thermometers Measuring cylinders Test

Chapter 7 and 8 discuss and give in depth details on photosynthesis and cellular respiration. They are the exact opposites in what they set out to complete in the cells of a leaf. Photosynthesis takes light energy and separates it in the chloroplasts to create glucose. Cellular respiration breaks down glucose to provide energy for the cell. The similarities between them include overlap in some of the enzymes and products and reactants utilized. The differences include the cycles and steps taken to

this energy through the processes of photosynthesis and cellular respiration. In photosynthesis‚ organisms harness light energy obtained from the sun to produce organic compounds. On the other hand‚ cellular respiration breaks down the organic compounds produced from photosynthesis to harvest the energy needed to carry out the energy-consuming activities of the cell. As complementary processes‚ photosynthesis and cellular respiration provide each other with the raw materials needed for each reaction

Photosynthesis and cellular respiration Introduction: Photosynthesis is the process which used by plants to capture light energy and use it to do chemical reactions that change carbon dioxide and water into oxygen and energy (ATP)‚ carbohydrates just like sugar. Cellular respiration is the process that releases energy by breaking down glucose and other food with oxygen. Plants cells do photosynthesis and cellular respiration both ‚but animal cells can only do the cellular respiration. In photosynthesis reaction
