Amylopectin The absorbance value(x) read from cuvette containing starch and water represents the total amount of starch-iodine complex. The absorbance value(y) read from cuvette containing starch‚ water and α-amylase at the respective temperature or pH represents the amount of starch-iodine complex which is left after the enzyme has hydrolyzed the starch.In order to get the amount of product;P (maltose and glucose) formed‚ need to subtract the (y) value from the (x) value.

huge amounts of energy‚ and their molecules are spread out as much as possible. With very little pressure‚ when compared to liquids and solids‚ those molecules can be compressed. It happens all of the time. Combinations of pressure and decreasing temperature force gases into tubes that we use every day. You might see compressed air in a spray bottle or feel the carbon dioxide rush out of a can of soda. Those are both examples of gas forced into a smaller space than it would want‚ and the gas escapes

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

All living things have catalase present in them. Catalase is a common HYPERLINK "http://en.wikipedia.org/wiki/Enzyme" enzyme found in nearly all living organisms that are exposed to oxygen‚ where it HYPERLINK "http://en.wikipedia.org/wiki/Catalyst" catalyzes the decomposition of HYPERLINK "http://en.wikipedia.org/wiki/Hydrogen_peroxide"

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

Introduction: The purpose of this experiment is to measure the effects of changes in temperatures and pH on enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚
