Why enzyme controlled reactions work better at room temperature?

The way enzymes work is by providing a bonding site at which various compounds (substrates) can come in contact and easily react with each other through some mechanism. If the temperature of the system is increased slightly, the substrates will have more energy and will thus collide more frequently, allowing for more reactions. However, if the temperature increases significantly, such as to the boiling point of water, they become extremely deformed, and since their function was dependent on their shape, this cripples their ability to catalyze reactions. While a few bonding sites may still be active, many will not, and those that are will have lost some of their functionality due to the change in shape

What are reactants that enter enzyme-controlled reactions?
substrate
What effect do temperature and pH have on enzyme controlled reactions?
enzyme require an optimum temperature and ph level to be active. temperature at which most enzymes are active is around 35-40 degree celcius. above this temperature the enzyme loses it globular structure and thus the substrate will not be able to bind with it. some enzymes are active in alkali ph while others are active in acidic temperature. but most of the enzymes are active in neutral ph and this helps to maintain its globular structure.
What factor do enzymes play in controlling reactions in metabolic pathways?
What is the role of enzymes in metaboli pathways A metabolic pathway is a particular sequence of enzyme-controlled reactions.
How could you determine the correct temperature range and salt concentration and pH for a specific enzyme?
Do a controlled experiment in which you get an enzyme and set them up in different temperature, salt concentration and pH levels and see which reacts the best.
How does increasing the temperature affect the rate reaction of an enzyme?
it generally helps because the temperature is the average kenetic engergy. that means that the substrates and enzymes can move faster and spread more quickly. the only problem is that enzymes can denature at higher temperatures. this means that at so high of temperature the enzymes lose their shape and then they can't bond to the substrates to catalyse the reaction.

substrate
What factors increase the rates of enzyme-controlled reactions?
** TEMPERATURE ** pH LEVEL ** PARTICLE SIZE ** SUBSTRATE CONCENTRATION
What is the series of enzyme-controlled reactions that build complex material from simple material?
Anabolism
What kind of chemical reactions speed up enzyme catalysis?
This varies per enzyme and what it catalyzes but chemical reactions that result in an increase in temperature often speed up enzyme catalysis.
Why above a certain temperature enzyme-catalysed reactions actually go more slowly if the temperature is raised?
because the enzyme is becoming denatured

Is temperature important to enzyme reactions?
Yes because if the heat is to hot it can damage the enzymes

What is the role of enzymes in metaboli pathways A metabolic pathway is a particular sequence of enzyme-controlled reactions.
Is temperature a factor that affects enzyme activity?
yes. at low temperature enzymes won't work as effectively, and at high temperature enzymes are denatured.

What is required in most of the Chemical reactions involved in metabolism?
A protein enzyme so that it will occur at body temperature.
3 variables that can cause an enzyme to lose its ability to function?
An enzyme is a catalyst for chemical reactions. Three variables that can cause an enzyme to lose its ability to function are temperature, pH level and concentration.
