Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide

Balloon Respiration Lab Introduction/ Background Cellular respiration is a process that releases chemical energy from glucose and other carbon-based molecules to produce ATP when oxygen is present. The formula for cellular respiration is C6H12O6+ 6O2= 6CO2= 6H2O. The process of respiration contains three main parts‚ glycolysis‚ Krebs cycle‚ and the Electron Transport Chain. The process of glycolysis takes place in the cytoplasm and is considered an anaerobic process which splits glucose into two

Cellular respiration‚ which synthesis ATP‚ begins with glycolysis‚ wherein a six-carbon glucose is broken down into two three-carbon molecules called pyruvate. This process requires the input of two ATPs to produce two pyruvates‚ two NADHs‚ and 4 ATPs. The NADHs are synthesised when NAD+‚ delivered by B vitamins‚ become bound to hydrogen and energised electrons1. Following glycolysis is the Krebs cycle and electron transport chain respectively. The Krebs cycle uses the two pyruvates produced in glycolysis

1.Explain the process of Cellular Respiration in order. Where does each step occur in a cell‚ which steps require oxygen‚ and how many ATP are produced in each step? Cellular respiration is the breakdown of glucose in the presence of oxygen to yield ATP. Glycolysis is the first stage in the breakdown of glucose and It occurs in the cell’s cytoplasm. It does not require oxygen (anaerobic). This step also occurs in two steps‚ the energy investment step‚ and the energy yielding step. This process yields

The Effect of Temperature on the Rate of Yeast Respiration Abstract Carbon dioxide is a waste product of yeast respiration. A series of experiment was conducted to answer the question; does temperature have an effect on yeast respiration? If the amount of carbon dioxide is directly related to temperature‚ then varying degrees of temperature will result in different rates of respiration in yeast. The experiment will be tested using yeast and sugar at different water temperatures. I

Name: Cellular Respiration—An Overview All cells need energy all the time‚ and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example‚ as you sit and read this sentence‚ you are breathing in oxygen‚ which is then carried throughout your body by red blood cells. But‚ some cells grow in envi¬ronments without oxygen (yeast

Cellular Respiration and Photosynthesis Photosynthesis is the process by which plants‚ some bacteria‚ and some protistans use the energy from sunlight to produce sugar‚ which cellular respiration converts into ATP‚ the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy‚ is associated with the actions of the green pigment chlorophyll. Most of the time‚ the photosynthetic process uses water and releases the oxygen. Cellular respiration

Problem: Does prior exercise affect the ability to squeeze a clothespin? Hypothesis: After exercise‚ people will be able to squeeze the clothespin faster than those without prior exercise. Materials: For this experiment a timer and a clothespin were used. Methods: To begin this experiment an individual was asked to squeeze a clothespin as many times as possible within one minute and the results were recorded. Then this same individual was asked to exercise (run in place‚ preferably)
