Food chains and webs not only describe the order organisms are eaten, but they also describe the flow of energy in an ecosystem. We and all things are made of energy, so the way that energy change forms and pass from one thing to another is one way to describe an ecosystem, and more in general it is a correct way to explain how life on Earth works.
When glucose is taken into the cell, the fluids or solutions in the cell become more concentrated (due to the absorbed glucose) than the fluids outside the cell. When this happens, a natural process called osmosis takes place .
Osmosis is defined as the movement of molecules of a solvent (in this case water) through a semi-permeable membrane (in this case the cell membrane) from a less concentrated solution to a more concentrated one in a bid to to equalize the concentration on both sides of the membrane.
<span>Water will therefore leave the less concentrated solution outside the cell, pass through the cell membrane and into the more concentrated solution.</span>
Answer:
a) both processes first break down glucose into pyruvic acid
Explanation:
Cellular respiration is the process through which cells of living organisms derive their energy. Cellular respiration can be carried out with oxygen (aerobic) or without oxygen (anaerobic). The oxygen actually acts as a final electron acceptor in the last stage of aerobic respiration process (ETC).
Cellular respiration starts with GLYCOLYSIS, which is the process whereby glucose is broken down to pyruvic acid. Glycolysis occurs in the cytoplasm and does not require oxygen to occur. In a complete respiration, the step progresses into the Kreb's cycle and Oxidative phosphorylation, which occurs in the mitochondria.
Hence, GLYCOLYSIS (break down of glucose to pyruvic acid) is a common process to both aerobic and anaerobic.
