Aerobic respiration in yeast Research question: What was the effect of anaerobic respiration in different environments determined the increase in size of a dough by the temperature? Hypothesis: It is hypothesized that if the temperature increases the dough will become bigger and bigger. Independent variable: (change) • Temperature • Height of the dough Dependent variable: (doesn’t change) • Amount of vegetable oil • Time • Volume of yeast solution Control variables: Variable

This scientific report will be based on cellular respiration‚ or fermentation. In specific‚ how the type of sugar affects the rate of fermentation. The aim of this experiment was to find which type of sugar was best suited to produce ethanol. In the experiment‚ four different sugars were used‚ they included sucrose‚ glucose‚ lactose and fructose. This research is still relevant today‚ as alcohol is still consumed and is required on a large scale. This makes it crucial to companies to find the best

cellular respiration. Cellular respiration is a metabolic process by which oxygen is used in the mitochondria to break down glucose in order to release stored energy. The process uses glucose and oxygen to generate carbon dioxide‚ water and ATP. The ATP produced is the main source of energy in organisms. Cellular respiration can occur via two processes: aerobic and aerobic respiration. Aerobic respiration is far more common‚ and efficient than anaerobic respiration. Aerobic respiration produces 38

Investigation Into Temperature Sensors Introduction In this project I will be investigating how it is possible to use a temperature sensor to keep a greenhouse from changing temperature too much. This is intended to help plants live and grow in their optimum temperature. This will create a perfect temperature for the enzymes in the plants to work in‚ and therefore resulting in a maximum growth/production rate. This could be useful for gardeners who wish to grow plants as quickly as possible

Heat and Temperature Heat is often described by the average individual as being the change in temperature from hot to cold. “Often the concepts of heat and temperature are thought to be the same‚ but they are not.” Heat and Temperature‚ para. 2) Perhaps the reasoning behind the incorrect reasoning is that humans associate the two together because when heat is applied to an object the temperature rises. The kinetic theory of matter better explains the underlying cause as to what takes place

AUTOMATIC TEMPERATURE CONTROLLED FAN H ere is a circuit through which the speed of a fan can be linearly controlled automatically‚ depending on the room temperature. The circuit is highly efficient as it uses thyristors for power control. Alternatively‚ the same circuit can be used for automatic temperature controlled AC power control. In this circuit‚ the temperature sensor used is an NTC thermistor‚ i.e. one having a negative temperature coefficient. The value of thermistor resistance at

Cellular respiration is the process of converting chemical energy of organic molecules such as glucose into a form of energy usable by organisms. This energy is mainly produced in the mitochondrial matrix and takes form in the molecule adenosine triphosphate [also known as ATP]‚ which is made up of an adenosine with a three phosphate tail group. The reason why ATP produces energy is due to the loss of the third phosphate group. The third phosphate‚ when released‚ releases the bond energy and supplies
