Cheyne-Stokes respiration

The energy currency for almost all living organisms is a compound called ATP, or adenosine tri-phosphate. This compound is made of up one adenine and three phosphate molecules which link together to form a structure like this: Adenosine Notice that the three bonds within this molecule become increasingly longer the farther away the phosphate is from the adenosine. This is to represent the fact that the bonds weaken as the distance between the adenosine and phosphates increases. This is…

iii) Light intensity, cm-2 Formula of light intensity = (1/distance2) = cm-2 Eg : for 10cm = 1/((10.00cm)²) = 1/(100 cm²) =0.0100 cm-2 Distance of leaf discs from the light source (±0.05) cm Light intensity (cm-2) 10.00 0.0100 15.00 0.0044 20.00 0.0025 25.00 0.0016 30.00 0.0011 35.00 0.0008 Table 6: The table shows the…

Adenosine Triphosphate (ATP) is the body’s main source of chemical energy. It is produced by breaking down nutrients such as glucose, fatty acids and proteins, which are all found in food. At the start of the race, anaerobic pathways are used to provide a quick source of energy. Most of this energy is derived from the catabolism of fats. Since lipids are more reduced than carbohydrates, they are capable of storing more energy per unit weight. Triacylglycerols are the lipids used for energy…

Renae Hallinan is an elite netballer, playing for the Adelaide Thunderbirds in the ANZ Championship League and the Australian Diamonds in the World Championships. Renae is required to work at a fast pace with an extremely high level of skill, as considerable demands are placed upon her anaerobic energy systems, with aerobic fitness assisting in her recovery between bursts of play. Netball games consist of four 15 minute quarters. There is a 3 minute break between the first and second quarter and…

The mitochondrion is an organelle which produces ATP or energy for all cells. The ATP produced by the mitochondria can be used to measure certain physical activities of fruit flies. In this experiment the development, climbing, flight, and in vitro activity of Drosophilia Melanogaster flies were tested. Three different strands of flies were used. One strand was the wild-type (wt) fly, which had normal mitochondria without any mutations. Another stand was the W501 strain (hybrid) which had…

Introduction: Investigating the effects of light intensity, NH4CL, and DCMU on the rate of electron transport in spinach thylakoid membranes was the purpose of this lab. Photosynthesis is the process that routinely drives electron transport across the thylakoid membrane but can be impacted when additional factors are added. Two phases known as the light reactions and the Calvin cycle makeup photosynthesis. Plastoquinone shuttle, water oxidation, and NADP+ reduction are the major factors of the…

Cellular Respiration is a cycle that can be found in all living organisms. The significance of Cellular Respiration is that it creates energy by breaking down larger molecules. For instance, the breaking down of a glucose molecule through the Glycolysis cycle. Although, cellular respiration includes both aerobic, with oxygen and anaerobic, without oxygen processes. According to Campbell’s Biology Cellular Respiration is, “[t]he catabolic pathways of aerobic and anaerobic respiration, which break…

The process of carbohydrate absorption after consuming food happens in a variety of pathways within the body. The first step to absorption is the process of digestion. This process begins in the mouth. Here, the enzyme a-amylase breaks down the food through the saliva. The process then moves to the small intestine where the digestion products are then absorbed through the intestinal wall into the blood stream and then moved across to other body cells. This then forms glucose and the disaccharide…

Glycolysis results in 2 pyruvates and 2 NADH , which are rich in energy and are used later to power ATP. Typically Oxygen is needed for cellular respiration but in glycolysis it is not necessary which makes it an Anaerobic process. In the absence of Oxygen, the pyruvates created through Glycolysis are rerouted through Fermentation. In the absence of Oxygen in order to keep Glycolysis going it will…

Anaerobic and aerobic exercise were determined to effectively influence muscle oxygen uptake at the cellular level. Evaluating and measuring the effectiveness of the two types of exercise on oxygen uptake would inform the advantages and disadvantages they have on muscles. Significant amounts of oxygen are consumed by the human muscles when moderate intensity aerobic work is performed. Contradictorily, anaerobic exercise causes the body to break down stored glycogen in muscles for energy.…
