Cellular Respiration In this lab the effects of different substrates on the rate of cellular respiration is being put to a test which is a very interesting experiment. The three major substrate solutions being used for this experiment are glucose‚ maltose‚ and alanine. The issues this experiment addresses are cellular respiration occur in different stages which are glycolysis‚ citric acid cycle‚ and fermentation. In this lab the experiment determines the effect of different substrates on

Yeasts’ capability of undergoing ethanol fermentation‚ its ability to ferment other sugars and artificial sweeteners‚ and how lactase influences yeasts ability to use lactose as a food source Kristina Naydenova Father Michael Goetz Purpose Part A: To investigate whether yeast has the ability to ferment glucose to produce carbon dioxide gas and ethanol. Part B: To investigate whether yeast has the ability to ferment other sugars and artificial sweeteners and how lactase influences their

and to compare the rate of cellular respiration in germinating and non-germinating soybeans. Fermentation breaks down sugars for a source of energy. Cellular respiration is the process used by cells to produce energy from nutrients. This process allows sugars and foods to be broke down in order to obtain energy from adenosine triphosphate (ATP). Cellular respiration is vital for survival of cells. Oxygen‚ which acts as the fuel is required for aerobic respiration. Oxygen helps breakdown food and turn

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

3 Yeast Metabolism Metabolism refers to the biochemical assimilation (in anabolic pathways) and dissimilation (in catabolic pathways) of nutrients by a cell. Like in other organisms‚ in yeast these processes are mediated by enzymic reactions‚ and regulation of the underlying pathways have been studied in great detail in yeast. Anabolic pathways include reductive processes leading to the production of new cellular material‚ while catabolic pathways are oxidative processes which remove electrons

is the movement of water across a membrane. It always navigates to the area of the membrane with a higher solute concentration. We take a closer look at the effects of osmosis in this lab through the examination of red blood cells (sheep)‚ plant cells (elodea)‚ and active transport in yeast. Under the microscope‚ we can determine the effects on plant and animal cells exposed to hypotonic‚ hypertonic‚ and isotonic sodium chloride solutions. Plant cells have a cell wall; however‚ animal cells do not

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. Photosynthesis produces NADPH2 in its workings‚ while aerobic respiration produces NADH+.

of this lab was to gain a complete understanding around the rate of cellular respiration within multicellular organisms‚ also to research and understand how to use a CO2. Background: Living systems require free energy and matter to maintain order‚ to reproduce‚ and grow. Energy deficiencies cause disruptions at the population and ecosystem levels as well. 1 mol of H2O produces 1 mol of CO2 through cellular respiration. Autotrophic organisms capture free energy from the environment through the process

and Respiration Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat: Photosynthesis is the process in which certain life forms are able to use sunlight to create energy. This energy is created by making carbohydrates from carbon dioxide and water in the presence of chlorophyll. Plants release large amounts of oxygen into the atmosphere as they produce much more than needed during the photosynthesis process. Aerobic respiration is an

Cellular Respiration: Using the Vernier LabQuest to detect CO2 gas production in germinating peas DESIGN Research Question: What is the effect of temperature on CO2 gas production in germinating peas? Background: The process of cellular respiration‚ which provides energy for cell growth and development‚ is an important part of life in germinating seeds. It converts the chemical energy of glucose into ATP. As a germinating seed respires‚ CO2 is produced as a byproduct. Therefore‚ the amount
