6/7 Photosynthesis and Cellular Respiration Review 1. _Energy__ is required for transport of certain materials‚ movement‚ growth‚ and reproduction. 2. Define autotroph and heterotroph. Name the organisms that make up each. Autotrophs use the suns energy to produce their food. Heterotrophs consume other organisms to obtain food. Plants Animals 3. ___Sun__ is the ultimate source of energy for all living things on Earth based on the cycle of photosynthesis and cellular respiration. 4. What

ADI Lab investigation: Photosynthesis Introduction and goals: In our experiment we worked with photosynthesis‚ which is the process of light energy‚ CO2 and H2O being turned into food for the plant. CO2+H2O+ Light energy=C6H12O+O2 is the formula for photosynthesis. Our group hypothesis was trying to determine weather o2‚ water‚ or the nutrients of the soil determine the mass of the water. The guided question was “Where does the mass that makes up a plant come from?” Methods:

The Effect of Temperature on the Rate of Yeast Respiration Abstract Carbon dioxide is a waste product of yeast respiration. A series of experiment was conducted to answer the question; does temperature have an effect on yeast respiration? If the amount of carbon dioxide is directly related to temperature‚ then varying degrees of temperature will result in different rates of respiration in yeast. The experiment will be tested using yeast and sugar at different water temperatures. I

HYPOTHESIS Using train conductors as representatives for all of human kind we can postulate with some accuracy the percent of the population of Earth that are complete and total assholes. If you have ever lived in a small town with train tracks running through it you will know that the conductor of the train is required to sound the whistle at every crossing. This is a 4-part whistle; 2 long‚ 1 short‚ 1 long. My hypothesis is that we can calculate what percentage of the population of planet Earth

Practical 5: determination of activation energy of an enzymed catalyzed reaction Introduction: enzymes are complex chemicals that control reactions in living cells. They are biochemical catalysts‚ speeding up reactions that would occur too slowly to be of any usefulness to an organism. Although in organisms‚ it is not necessary for the reactions to be at maximum rate at all times. Enzymes interact with other molecules to produce a stable system in which the products are made when they are

inorganic cofactor such as Magnesium to the rate of respiration of yeast was determined using Durham tube assembly with the substrate glucose. After thirty minutes‚ the test tube with the cofactor in the form of Magnesium sulphate MgSO4 showed the higher amount of carbon dioxide evolved which was measurable through volume and was one of the by- products of cellular respiration. This stated that the higher amount of CO2 evolved‚ the higher the rate of respiration. Thus‚ the hypothesis “If enzymes need cofactors

Photosynthesis is a crucial energy conversion process that occurs in the chloroplasts of eukaryotic cells. The rate of photosynthetic activity holds importance in environmental‚ horticultural and agricultural situations. (Boardman‚ N.K. 1977). Pigments in the chloroplasts thylakoid membrane absorb the electromagnetic radiation from a light source and release an electron into the electron transport chain. DCPIP’s chemical ability to favourably accept electrons‚ and undergo a colour change from

Cellular Respiration and Fermentation Facts to Remember 1. Cellular respiration is a catabolic series of reactions. 2. All living forms conduct some form of cellular respiration‚ either aerobic or anaerobic. a. Aerobic is in the presence of oxygen b. Anaerobic is in the absence of oxygen or none oxygen requiring. 3. The starting molecules consist of the biological molecules with carbohydrates (monosaccharides) as the first choice. The order of use is given below. a. Carbohydrates b.

maintain their function. In photosynthesis and aerobic cellular respiration energy is being produced to cycle carbon between the functions. There is the function of maintaining life‚ helping aid chemical reactions‚ using the cell to help aid reation. All of these recycling processes help creates energy that is then in return used to aid their specific function. The life processes of nutrition and respiration are related to photosynthesis and Aerobic Cellular Respiration. All organisms use material
