Respiration and Photosynthesis Respiration and photosynthesis are reactions that take place in the environment which complement each other, in the other case can be seen as a same reaction but happening in reverse of each other (Tang, 2005). In photosynthesis the ingredients/ requirement for it to place is water and carbon dioxide as they release oxygen and glucose as the products. Respiration to take place requires glucose and oxygen to yield carbon dioxide and water. Since the product of…

Fatty acids and oil are organic substances, which are composed of carbon, oxygen and hydrogen. When carbon, oxygen and hydrogen are chemically combined with a carboxyl group, a long chain is formed, called as fatty acids. Alternatively, when fats react with water, they break into fatty acids and glycerin. Three chains of fatty acids when react with glycerol molecule, they combine to form triglycerides. Molecules of triglyceride are the basis of fats and oil. The difference in their chemical…

1. Did the carbon dioxide concentration in the classroom change as you monitored it during the Preliminary Activity? Why did it change (or not change)? Yes the carbon dioxide concentration in the classroom did change as we monitored it during the preliminary activity. It had dropped and become stagnant then dropped even lower before rising back to stagnant levels. This may be because there may have been a slight ventilation in the room at around 125 seconds. 2. What is the role of carbon…

What are the processes involved in cellular respiration? How do enzymes perform an important role in the mitochondria? How does the mitochondria use chemiosmotic gradients? How did the mitochondria evolve? The mitochondria are organelles found within eukaryotic cells, that produce energy for the cell. There are many chemical processes and important molecules involved in the mitochondria. Cellular respiration is the chemical process that makes the energy needed for the cell in the form of ATP.…

Total Energy Cost Laboratory Introduction: There are three energy systems that produce ATP. First is the ATP-PC system (high power and short duration), Glycolytic System (moderate power and moderate duration), and the oxidative aerobic system (low power and long duration). In this lab, a subject weight lifted for one minute. At the start, the Phosphagen system immediately took place. This system, also called the ATP-PC system is the quickest way to re-synthesize ATP, and is a rapid supply of…

In order to obtain energy through food, organisms perform the process of cellular respiration in which they break down a molecule of sugar and use it to produce many molecules of ATP, which is the chemical energy nearly all organisms use. However, this process is aerobic, meaning it only occurs in the presence of oxygen. When an organism needs to produce ATP without oxygen, such as during intense periods of exercise, it uses fermentation to convert food into energy. In fermentation, the molecule…

Lipocalin-2 (LCN2) is a small secreted adipokine that binds and transports small hydrophobic molecules such as fatty acids and steroids. In addition, LCN2 limits bacterial growth by sequestering iron-containing siderophores. In mammalian liver, LCN2 protects against inflammation, infection, injury and other forms of cellular stress. Because previous work indicated that LCN2 is a key modulator of hepatic fat metabolism and homeostasis, we performed a comparative profiling of the proteins and…

I’m aware that all exercise is not created equal and this is where aerobic and anaerobic exercise come in. Although the two may differentiate, both burn fat as well as boost metabolism. During aerobic exercise, oxygen is carried through our breath to the muscles giving them sufficient intake of energy needed to sustain long periods of light activity without needing to take energy from another source. During anaerobic exercise, there is no oxygen being carried to the muscles, therefore these…

Competition is a prevalent factor in biology that plays an integral role in the diversity of a biomes community and natural selection for species. Plants are among the most diverse groups of organisms and it all started 475 Ma ago, when spore-producing plants were the first to emerge from the sea to begin the colonization of terrestrial ecosystems. Ever since late Silurian (425 Ma), land plants have been competing, evolving and diverging to give rise to new species, while nearly all plant…

Purpose The purpose of this lab is to determine the effect of light intensity on the rate of cellular respiration in seaweed. Introduction The relationship between respiration and photosynthesis in plants is a constant one. During photosynthesis plants use light energy, often from the sun, combined with carbon dioxide and water to produce energy. The byproducts of this action are glucose and oxygen. Contrarily, respiration is the combination of glucose and oxygen to produce water and carbon…
