Suggest how increasing the temperature effects the rate of reaction of enzymes

Increasing the temperature of the reaction mixtures increases the average kinetic energy possessed by particles in the reaction mixture aka particles move faster. This increases the frequency of collision between enzymes and substrates particles hence increases the frequency of effective collision in the correct orientation thus increasing rate of enzyme substrate reaction.

However, if the temperatures increases too high, the bonds in the enzymes' structure (hydrogen bonds, hydrophobic interactions) will be disrupted, altering the 3D structural conformation of the active site of the enzyme. Substrates will no longer be able to recognise and bind to the enzyme hence the enzyme can be considered to be denatured, with a loss of function

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
