Anaerobic respiration is responsible for the CO2 during the process In order for bread to be made it needs to have CO2 and anaerobic respiration is there for that How Weight each ball of dough. There are two types of respiration – aerobic (which needs oxygen) and anaerobic (which doesn’t need oxygen). Respiration is a redox reaction that processes A CO2 Gas Sensor Probe is used to measure the amount carbon dioxide produced as the cellular respiration occurs which is proportional to how much of the molecule is decomposed. Time We need a timer PROBLEM STATEMENT: The table summarises some differences between the two types of respiration. If we see graph 1 we can see that the line that indicates de results for water at 40° is increasing as time passes. During bread production, yeast starts off respirating aerobically, creating … Write the equation of aerobic repiration and anaerobic respiration in the yeast cells and muscle cells. The substrate which I chose to further investigate was fructose. Aerobic respiration occurs in presence of oxygen in mitochondria whereas, anaerobic respiration occurs in absence of oxygen in cytoplasm. Aerobic respiration requires oxygen, and anaerobic respiration does not. Although this kind of respiration is less efficient in producing energy, because it produces only two ATP molecules in comparison to the 38 molecules produced during aerobic respiration, however, this form of respiration is very primitive and had actually started from the time when oxygen was missing in our atmosphere. Instead of oxygen reaction with the hydrogen to continue the processes such as the electron transport chain and … : Glucose ---->Latic Acid+Energy. It is quite common in fungi (e.g., Rhizopus, Yeast) and bacteria. By looking at the formula of anaerobic respiration in fungi (yeast) & bacteria: We can see that yeast contains glucose, because if the product is CO2 , the have to contain glucose. o Enzyme concentration (in this case, yeast). 2. Carbon dioxide is a waste product of yeast respiration. Also it is worthwhile mentioning that yeast feeds on sugar very well, and so that I decided to use glucose. Anaerobic Respiration. Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain. As yeast respires, an increasing volume of CO2 in the flask is produced, increasing pressure and causing the stained water drop to move along the tube. Carbon dioxide is a waste product of yeast respiration. Aim: To measure the rate of anaerobic respiration in yeast at different temperatures using a gas syringe. Hypothesis: 2% yeast solution This seemed like the perfect lab to add in order to compare aerobic and anaerobic respiration with yeast.
