b. Metabolism is the breakdown of foods to provide energy for the body. Breaking down the foods use cellular respiration which requires glucose and oxygen and produces carbon dioxide. The faster the metabolism, the more cellular respiration will occur which causes an increase in oxygen to be consumed. The effect of temperature will cause an increase on metabolic rate till a certain point where then the cell will become denatured because it is out of its range. In test variety A, the corn in the 22C had a higher oxygen consumption compared to the one placed …show more content…
The rate of oxygen consumption and metabolism will be much lower for the variety A seedling. The process of cellular respiration will be slowed down because it no longer has the energy carrier. Cellular respiration requires NADH to return to NAD+ for glycolysis to take place. Without NAD+ being available to take the electrons in glycolysis, it will stop the process of glycolysis, electron transport chain, and Krebs cycle which will cause the rate of metabolism and oxygen consumption to drop. It will also stop the production of ATP because NAD+ is used in the process of making ATP.

a. In step 1, the key metabolic process is photosynthesis. In photosynthesis, the plants use carbon dioxide and light energy and produces glucose and releases oxygen. Carbon dioxide is broken down in the Calvin cycle and is produced into a 3 carbon sugar organic molecule. In step 2, the process is cellular respiration. An animal would eat the organic molecule and break it down and take in oxygen and would produce carbon dioxide and water. The carbon dioxide is produced in the Krebs cycle and is released into the atmosphere in where it can be used for photosynthesis.

Increased carbon dioxide in the atmosphere results in greater acidification because the carbon dioxide is dissolved in the ocean which leads to carbonic acid being produced. Since carbonic acid is acidic, it causes the acidity of the ocean to increase. The increased acidity will lead to enzymes not working at the optimal pH because the change in pH will lead to decrease in efficiency of the enzymes in the ocean. Another effect of the increase of ocean acidity will cause the shells of the organisms to become harder to make and require more energy because the carbonic acid forms bicarbonate and causes less carbonate be available for the organisms to use to make their shells. Human activity can increase carbon dioxide by deforestation which removes the organisms that convert carbon dioxide into organic molecules. With less organisms available to do photosynthesis, there will be an increase in carbon dioxide. Another way human activity increases carbon dioxide is by burning fossil fuels. By burning the fossil fuels, it releases carbon dioxide into the
