Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the process that breaks down food to use as energy. The three main stages are glycolysis‚ citric acid cycle‚ and electron transport (Simon‚ Reece‚ & Dickey‚ 2010). • What is the role of glycolysis? Include the reactants and the products. Where does it occur? During glycolysis‚ a team of enzymes

How does photosynthesis impact the flow of energy and the cycling of nutrients‚ you ask? Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis provides the base for the one way flow of energy through the biosphere. Plants convert energy from the sun into sugars‚ which provide fuel for themselves and for other organisms. Photosynthesis also cycles carbon and oxygen nutrients through the

Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the process by which cells harvest energy that is stored in food. The three stages are glycolysis‚ citric acid cycle‚ and electron transport. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis which mean splitting sugar‚ with oxygen it is

Glycolysis Two stage process Stage 1 – trapping and destabilising glucose in order to produce 2x3c molecules (5steps in the process). Requires energy (2 ATPs) Stage 2 – oxidation of the 3c molecules to pyruvate (5steps in the process). Energy generated (4tps and 2 NADH) Stage 1 Step 1 – trapping glucose‚ glucose enters via facilitated diffusion through specific transport proteins. The family of transporters is known as GLUT‚ GLUT 3 (brain‚ nerve tissue) Low Km allows relatively constant rate

Why Oxygen is Important Oxygen plays a vital role in the treatment of patients. Oxygen is the molecule that helps the cells in our body produce ATP through a process known as cellular respiration. Also it is the number one drug of choice for the American heart association. Finally it is a priority according to the universal care protocols in the protocol book given to flight medics in USAAAD at Fort Polk. In short Oxygen is important for the medics to use. To start off with oxygen helps sustain

CHAPTER 7 LECTURE SLIDES Respiration • Organisms can be classified based on how they obtain energy: • Autotrophs – Able to produce their own organic molecules through photosynthesis • Heterotrophs – Live on organic compounds produced by other organisms • All organisms use cellular respiration to extract energy from organic molecules Cellular respiration • Digestion – enzymes breaking down large macromolecules into smaller ones. • Cellular respiration is a series of reactions

THE PROCESS OF FERMENTATION THROUGH DIFFERENT KINDS OF SUGARS In order to produce ethyl alcohol fermentation‚ we had to determine what sugars used‚ such as glucose (a single sugar) sucrose (table sugar) and lactose (milk sugar) will react with yeast to produce ethyl alcohol fermentation. My hypothesis is that the sugar lactose would produce the highest amount of bubbles and ferment. INTRODUCTION: The significance of fermentation is a lengthy process that has been practiced by humankind

prosper. Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae. Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves‚ and little to none occurs in stems.. The upper and lower epidermal cells do not

Photosynthesis: Plant cells vs. Solar Cells Chevon Allen 01/23/2010 SCI-115 Professor Garcia Photosynthesis and the semiconductor-based solar cell are very similar process with different ways of reaching the same goal. In photosynthesis‚ plant cells harness the solar energy of the sun with carbon dioxide to transform water molecules into hydrogen‚ oxygen‚ and electrons. Just like photosynthesis‚ Semi conductor based solar cells harness the solar energy of the sun for the same purposes
