    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

    Misael Acosta Photosynthesis Lab Report Ms. Rocha AP Biology 4th Period II. Intro/Background 1. In order for oxygen to be present photosynthesis must occur. Photosynthesis takes in light and CO2‚ and through a series of steps produces oxygen. Photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. Examples include the production of O2 or the consumption of CO2. All the oxygen within the leaf disks will be removed before being placed

    Title: Rate of Photosynthesis Introduction: Photosynthesis occurs in plants where the light energy changes to chemical energy. This process occurs in the chloroplast of the plant cell in order to have gas exchange in the organism. Purpose: To measure the effect of light intensity on the rate of photosynthesis in the leaf cells. Hypothesis: The higher the concentration of the sodium bicarbonate solution‚ the faster the leaf of the plant will rise to the surface of the water in the beaker‚ the

    The purpose of this lab was to investigate whether veins affect photosynthesis rate. It was predicted that having veins would decrease the rate because chloroplast might be less frequent due to the vascular tissue. For this experiment‚ 4 groups were set up: veins and no veins in CO2 solution‚ and veins and no veins in distilled water‚ the distilled water groups served as controls. These 4 groups were placed under a light bulb in order for photosynthesis to occur. No disks experience movement in the

    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

    pigments of spinach leaves can be separated. The knowledge gained in this experiment is relevant to understanding how the process of photosynthesis works. A Real-world application for this includes the harvesting of clean energy sources‚ as scientific advances have led the way to artificial photosynthesis on the path to replace fossil fuels (Nath‚ 237). Photosynthesis converts light received from the sun into chemical energy known as ATP. Visible light is absorbed by the pigments found in plants. Carbon

    Lab Report: Photosynthesis Name: Purpose of this Lab What is the goal of this lab? What question are you trying to answer‚ or what problem are you trying to explain? In this lab I will perform experiments to explain photosynthesis. I will answer questions like what does photosynthesis do and how does photosynthesis work? Hypothesis After reading the lab instructions (but before starting the lab) record your best educated guess about what will happen in the experiment. Explain

    strong‚ a foundation known as photosynthesis. When photosynthesis is functioning as it should‚ in its fullest capacity‚ all organisms benefit from it in some way. Furthermore‚ scientists aim to better understand the photosynthetic process to help enhance the efficiency and quality of life on Earth. By fully understanding the function of photosynthesis‚ some environmental adjustments can then be made to refine the photosynthetic process. In this lab specifically (Lab No. 7)‚ we isolated specific color

Alyssa Wright VARIABLE: LIGHT INTENSITY AIM: to investigate the effect of light intensity (lux) on the amount of oxygen produced (number of bubbles) HYPOTHESIS: I predict that the rate of oxygen produced increases‚ as the light intensity increases‚ but only to a point. I predict this will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen
