I believe it is "All living organisms are composed of cells."
Aerobic respiration is a biological process that takes energy from glucose and other organic compounds to create a molecule called Adenosine TriPhosphate (ATP). ATP is then used as energy by nearly every cell in the body -- the largest user being the muscular system. Aerobic respiration has four stages: Glycolysis, formation of acetyl coenzyme A, the citric acid cycle, and the electron transport chain.
The first step of aerobic respiration is glycolysis. This step takes place within the cytosol of the cell, and is actually anaerobic, meaning it does not need oxygen. During glycolysis, which means breakdown of glucose, glucose is separated into two ATP and two NADH molecules, which are used later in the process of aerobic respiration.
The next step in aerobic respiration is the formation of acetyl coenzyme A. In this step, pyruvate is brought into the mitochondria to be oxidized, creating a 2-carbonacetyl group. This 2-carbon acetyl group then binds with coenzyme A, forming acetyl coenzyme A. The acetyl coenzyme A is then brought back into the mitochondria for use in the next step.
The third step of aerobic respiration is called the citric acid cycle -- it is also called the Krebs cycle. Here, oxaloacetate combines with the acetyl coenzyme A, creating citric acid -- the name of the cycle. Two turns of the citric acid cycle are required to break down the original acetyl coenzyme A from the single glucose molecule. These two cycles create an additional two ATP molecules, as well as six NADH and two FADH molecules.
The final step in aerobic respiration is the electron transport chain. In this phase, the NADH and FADH donate their electrons to make large amounts of ATP. One molecule of glucose creates a total of 34 ATP molecules.
Hope this helps!
Answer:
The correct answer is ''shield volcano.''
Explanation:
Shield volcanoes are those whose diameter is much greater than its height. They are formed by the successive accumulation of very fluid lava flows. So they are of considerable height and slight slope. Its topography is smooth and its top forms a poorly defined depression. Lava ejected during an eruption is largely basaltic in composition and has a very low viscosity (it is liquid). Because of this, lava flows easily and spreads over a large area.
Shield volcano eruptions generally involve lava that travels great distances and spreads out in thin layers. As a result, the volcanic mountain that is built over time by repeated lava flows has a broad, smooth profile leading away from a bowl-shaped depression at the top known as a caldera.
