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…

Lcn2-deficient mice or WT mice fed an MCD diet. Significant changes to m/z signal intensities for various sphingomyelins, triglycerides, and glycerophospholipid species were observed, including elevations of phosphatidylinositol diphosphates and -triphosphates in MCD-fed mice, regardless of LCN2 status. Interestingly, two arachidonic acid containing glycerophospholipids were increased in Lcn2-deficient livers, suggesting that LCN2 loss interferes with arachidonic acid metabolism. Lastly,…

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…

What is UGT1A4? The majority of drugs are metabolized to form compounds that are more polar in structure than their parental precursors. The ultimate goal is to 1) increase the hydrophilicity of the presented compounds along with their molecular weight, 2) inactivate their biological effects and 3) facilitate their efflux from the cells, subsequently followed by excretion into bile or urine1. The metabolic enzymes in charge of this process are traditionally organized into two separate…

Active and passive transport move oxygen, water, and nutrients into cells and remove waste. Active transport requires a chemical energy because it moves from lower concentration to areas of higher concentration. It uses ATP to pump the molecules against the concentration, which requires cellular of solute. Passive transport moves from areas at a higher concentration to low concentrations, so it doesn’t require energy. Active transport takes place in the membranes of both the mitochondria and…
