- E. coli cells require organic compounds, such as glucose as its carbon and energy source, and prefer to live in an fully oxygenated environment. Which of the following is the most accurate way to describe E. coli based on its trophic properties? O Chemolithoautotroph Phototroph Anaerobic bacterium O ChemoorganoheterotrophWhy is nitrogen a limiting nutrient for so many organisms, and what is it used for? (consider the four types of organic molecules)We have seen that energy is essential for life on earth. All organisms need energy to maintain their cellular processes. There are two basic ways of generating energy de novo, at the base of food webs. Describe the two primary ways that autotrophic organisms generate energy, including the original source of energy and the primary organisms that carry out each process.
- You are observing an organism. It appears to extract energy stored in inorganic molecules like ammonia, nitrites and hydrogen sulfide; it uses carbon dioxide as its primary carbon source. What kind of organism is it? (Hint: think nutrition groups)of biologically available nitrogen? What inorganic nitrogen pool is composed of N2 and in the ultimate source (one word)All of the following are ways microorganisms adapt to limited nutrients except: synthesize increased amount of enzymes for uptake and metabolism of limited nutrients form metabolically active highly resistant endospores synthesize enzymes needed to use a different nutrient acetic acid adjust the rate at which they metabolize nutrients
- What is the mode by which organisms acquire nitrogen from the surroundings How do we maintain a steady supply of amino acids in the body? please answer allBiological Oxygen Demand (BOD) is a measure of? How much oxygen needed is needed for growth of aerobic bacteria The extent to which rivers or lakes are polluted with inorganic industrial waste compounds How much oxygen is needed for survival of aerobic bacteria The extent to which rivers or lakes are polluted with organic waste compoundsWhy is nitrogen fixation so energetically costly?
- Why must nitrogen fixation occur in an anoxic (i.e., oxygen-free) environment? a)Because H2 is an additional product of nitrogen fixation, and the combination of H2 and O2 would cause the cell to combust. b)Oxygen poisons the dinitrogenase enzyme by entering the FeMo cluster c)Oxygen competes as an electron acceptor in the ETC, so electrons cannot be passed to N2. d)Oxygen "steals" electrons from the dinitrogenase reductase, producing free radicals.Discuss the concept of apparent free space. What role does apparent free space play in the uptake of nutrient ions?why are underground storage organs like onions, carrots, cassava, potatoes, etc high in carbs and water and low in fat and proteins? And why is this important?
