    reproduction. Photosynthesis & cellular respiration are the main pathways of energy flow in living things. Photosynthesis is a process by which plants and some other organisms convert‚ light energy from the sun‚ CO2 from the air & H2O from the earth‚ into chemical energy stored in molecules like glucose. Cellular respiration is a process in which O2 is delivered to cells in an organism & metabolic process in cells leads to the production of ATP by the breakdown of organic substances. Cellular respiration

    Photosynthesis is the process of transforming light energy into chemical energy that is used to build carbohydrates. Light reactions occur in the thylakoid membrane of the chloroplast‚ sunlight and water are the substrates for this reaction. The conversion of light energy can go through two pathways: noncyclic and cyclic. In noncyclic light transport‚ both Photosystems II and I are involved producing ATP and NADPH. Photosystem II absorbs 680 nm of light energy‚ with the oxidation of water; chlorophyll

    Respiration” and “Photosynthesis” All life depends on two chemical reactions “Respiration” and “Photosynthesis”. These two processes are quite crucial because they are a source to nearly all life on Earth. Both of these processes are quite similar yet differentiate vastly. In this essay I’ll be comparing and contrasting “Photosynthesis” and “Respiration”. I’ll start by discussing what actually happens

    Cellular Respiration Cellular respiration is a chemical process that produces adenosine triphosphate‚ or otherwise known as ATP for energy that is also needed to survive. It leaves waste products‚ carbon dioxide and water‚ which is needed for photosynthesis‚ a process that only plants use. Production of ATP through the process of cellular respiration occurs in the mitochondria of the cytosol inside plant and animal cells. Cellular respiration occurs in three stages‚ Glycolysis‚ which happens in

    Abstract The effect of nature of substrates on the rate of cellular respiration in yeast was determined by using the Smith fermentation tube method. Mixtures of 15ml distilled H2O‚ 10% yeast suspension and 15ml of the following solutions (all at 10% concentration):1- starch‚ 2 – lactose‚ 3 – sucrose‚ 4 – glucose‚ 5 – fructose‚ 6 – distilled water ‚ were poured in six smith fermentation tubes. Cotton balls were plugged in the openings of the tubes and the tubes were kept upright and observed for

    INTRODUCTION Cellular respiration is a biochemical pathway in which cells produce ATP or energy and carbon dioxide as metabolic waste by breaking down the chemical bonds of food molecules. Cellular respiration is a type of aerobic respiration which needed oxygen in order to produce ATP which occurring in the mitochondria. Meanwhile‚ in the absence of oxygen‚ the cells will undergo anaerobic respiration to produce ATP in the cytoplasm. Anaerobic respiration can be divided into two parts which are

    In photosynthesis‚ light energy is transformed into chemical energy‚ thus chemical energy is the product. This is different from respiration because respiration transforms chemical energy into energy usable by cells; in this case chemical energy is the source. Photosynthesis occurs in the chloroplasts‚ using the chlorophyll inside of the chloroplasts‚ while respiration occurs in the mitochondria. Photosynthesis produces oxygen as a by-product‚ while aerobic respiration requires oxygen to even work

    Cellular Respiration Lab Report Wednesday 8:00 A.M. Lab March 2nd‚ 2005 I. Introduction In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease
