Respiration

In regards to both the mean change in respiration rate and the mean change in pulse rate, the results indicate no statistical significance in difference (Appendix 2.1 & 2.2). Consequently, the null hypothesis is rejected in favour of the alternative hypothesis stating that acute caffeine consumption does not increase heart and respiratory rate, and therefore does not elevate aerobic performance. These results are not consistent however with related research that asserts caffeine as a stimulant…

PURPOSE To determine how germination and temperature of environment effect respiration rate of seeds. BACKGROUND INFORMATION Cellular Respiration: Is the controlled release of energy from organic compounds in cells to form ATP. Sugar + Oxygen → Carbon dioxide + Water + Energy (ATP). In eukaryotic organisms, respiration occurs to maximize ATP production; this is contrary to anaerobic respiration, which occurs during the absence of a ready supply of oxygen (mostly in prokaryotic organisms).…

Cellular respiration is “The series of metabolic processes by which living cells produce energy through the oxidation of organic substances” (dictionary.com). These metabolic processes are fueled through O2 consumption. The equation of cellular respiration is as follows: C6H12O6 + O2 ---> CO2 + H2O + ATP (Pidwirny). The actual pathways of cellular respiration are glycolysis, pyruvate oxidation, and oxidative-phosphorylation (Campbell pg. 166). The big picture problem is the rate at which this…

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…

anaerobic respiration? “During anaerobic respiration, less energy is released than during aerobic. This is because the breakdown of glucose is not complete. What it does to your muscles is it releases much less energy than it needs. Due to this, anaerobic respiration produces an oxygen debt that is the amount of oxygen needed to oxidise lactic acid to carbon dioxide and water” (http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa/respiration/respirationrev4.shtml). “Anaerobic respiration…

Cellular Respiration Cellular respiration is a 3 step process that makes energy. Every organism on earth needs cellular respiration to survive because without energy an organism cannot survive. The chemical formula for cellular respiration is C6H12O6+6O2 > 6CO2+6H2O+38 ATP. So how do runners perform cellular respiration in a race? First the runner must breath in and air goes through the mouth and through the air way to get to the lungs. The lungs then take oxygen from the air and diffuse it…

Respiration and Excretion In this lab we tested to see if respiration was a form of excretion. We were testing for the excretion of salt and water. When testing for the excretion of water, we placed a test strip in our palms/hands and closed them to a fist for 1-2 minutes. We then took a blue test strip of silver nitrate and placed it into a zip lock bag for our control. We would also take to additional blue strips and place one into a zip lock bag and begin respiration process of exhaling…

Result to Mutation on the three Stages of Cellular Respiration Mary A Enriquez University of the Pacific November 11, 2014 2 Green Dr. Geoffrey Lin-Cereghino Abstract: The purpose of this lab is to determine which type of food source could possibly help strains grow on both permissive and restrictive temperature. Based on all the chemicals accumulating, we can determine the enzymes that are used to inhibit the three stages of cellular respiration. Introduction: For cells to…

Cellular respiration is a process that takes place in the mitochondria where a chain of metabolic reactions occur in order to generate chemical energy from nutrients such as carbohydrates. The key reactants of this process include oxygen and glucose which yield carbon dioxide and water. Photosynthesis is the process where light energy is converted into chemical energy. The key reactants in photosynthesis are water, light and carbon dioxide which yield glucose and oxygen. In this lab, several…

There are key differences between cellular respiration and photosynthesis that can help one learn about each process on a deeper level. Cellular respiration’s goal is to break down certain food molecules like sugars, fats, and carbohydrates and convert it to ATP or energy for the cell to use. For photosynthesis, its purpose is to obtain solar energy and convert that energy into chemical energy and glucose for food and an energy storage. Cellular respiration occurs in the mitochondria, which is…
