Unformatted text preview: Cell Energy Worksheet SCI/230 Version 7 1 Associate 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 in which cells produce the energy they need to survive. The three stages are: • Glycolysis • Krebs Cycle/The Citric Acid Cycle • Electron Transport Chain • What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis is the initial process of most carbohydrate catabolism. The generation of high-energy molecules as cellular energy sources as part of anaerobic and aerobic respiration. This process in the cell can have oxygen present and sometimes may not. Production of pyruvate for the citric acid cycle as part of aerobic respiration. The production of a variety of six- and three-carbon intermediate compounds, which may be removed at various steps in the process for other cellular purposes....

The Creation of the Ocean Floor 2 The Creation of the Ocean Floor The ocean is a mysterious place where scientists continue to unravel the secrets it holds within. The creation of the ocean floor is a continual motion of plate boundaries moving and shifting the sea bed. With the shifting of these plate boundaries natural disasters such as earthquakes, tsunamis, and volcanic eruptions can occur. The theory of plate tectonics has been around since 1960; the theory of continental drift includes several knowledgeable arguments in defense of one or another. In an interview with Jacques Cousteau in 1996, he said “I said that the oceans were sick but they're not going to die. There is no death possible in the oceans. There will always be life but they're getting sicker every year” (Win Wisdom, 2011). Plate Boundaries Three different plate boundaries include Divergent, Convergent, and Transform plate boundaries. A divergent boundary occurs when two tectonic plates move away from each other. Along divergent boundaries, lava spews from long fissures, geysers spurt superheated water, frequent earthquakes strike along the rift, and beneath the rift magma (which is molten rock) rises from the mantle. The magma oozes up into the gap and hardens into solid rock, forming new crust on the torn edges of the plates. The magma from the mantle solidifies into basalt which underlies the ocean floor. At divergent boundaries oceanic crust is created.
