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 are reactants that enter enzyme-controlled reactions?
substrate
What is the effect of excess heat or temperature on an enzyme-?
With a lot of heat, the enzyme will be denatured meaning it will lose its shape and therefore its function.
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.
What must be held constant when testing the effect enzyme concentration on enzyme activity?
temperature,pH and substrate concentration
What are reactants that enter enzyme-controlled reactions?
substrate
What three conditions can effect enzyme reactions?
1. Temperature (high temperature might denature an enzyme) 2. Concentration of substrate 3. Presence of a catalyst
What is the effect of excess heat or temperature on enzyme?
Each enzyme has its ideal temperature
What is a special protein that effect the rate of chemical reactions?
An enzyme
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
What can effect the shape of an enzyme molecule?
Temperature
What is the effect of excess heat or temperature on an?
Each enzyme has its ideal temperature
What is the effect of excess heat or temperature on an enzyme-?
With a lot of heat, the enzyme will be denatured meaning it will lose its shape and therefore its function.
Is temperature important to enzyme reactions?
Yes because if the heat is to hot it can damage the enzymes
