The pathway for the reverse electron flow in an organism that spends ATP from fermentation to form NADH. Introduction: The electron transport system (ETS) is the last pathway involved in the cellular respiration that occurs in mitochondria. The ETS is involved in the formation of ATP (adenosine triphosphate) molecules upon complete hydrolysis of organic molecules. Fermentation is a process where the organic molecules are broken down by microorganisms such as bacteria or yeast.

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

Use drawings, flow charts, or a table to compare and contrast the energy inputs and outputs during each phase of aerobic respiration vs. fermentation. Be sure to directly discuss inputs and outputs of BOTH processes. Include all phosphorylated compounds and high-energy electron carriers, and briefly EXPLAIN HOW these are produced at each stage of respiration. WHERE does each stage happen? Explain HOW energy from high energy electron carriers is converted to ATP during respiration in mitochondria or aerobic bacteria.

Consider how the Hill Reaction might be used to investigate how the wavelength of light influences the rate electrons move in the electron transport chain of the chloroplast. a) Design an experiment to compare the effects of blue light and green light on the Hill Reaction. (Assume that you have filters that you can attach to your light source to control the wavelength of light.) b) Based on your knowledge of photosynthesis, how would you expect the color of the light to effect the movement of electrons? c) Draw a line graph of your expected results.
