It is affected by those things. Precisely how ... well, if you knew the answer to that, you'd probably know how to solve the protein folding problem, and there would be big money and fame in that. In other words: I'm not going to be able to explain it in a paragraph or two. Suffice to say that it is affected by those (and other) things.

∙ 14y agoDifferent Enzymes are effected differently. Most Enzymes have an optimum pH and Temperature though if the fall above or below this the rate at which an enzyme induces or canalizes reaction may be lowered or stopped completely(I am not aware if it can have a reverse effect, I do not believe so).
For example: The enzyme Pepsin has an optimal range of pH 1.5-3 anything outside this and Pepsin (a digestive enzyme in the stomach) will not work at full capacity. Temperature also affects Pepsin; it works best at 98.6oF to 107.6oF. After Pepsin reaches boiling, it stops working completely.

∙ 13y agoSome side chains are either basic or acidic. Changing the pH changes the protonation state of these side chains, making them either more or less hydrophilic, which in turn affects whether it is energy-favorable for them to be on the interior or exterior of the protein.
That's about as simple as I can make the answer.

∙ 11y agoEnzymes are proteins.Normally reacting speed is doubled when temperature is increased from 10 celcius.But only upto 40celcius.If temperature is above 60celcius reaction stops. Each enzyme has a optimum pH.Some work best in basic medium while some work in acidic.Many enzymes have a optimum pH between 6-7.

How does heat affect the enzymes in a chemical reaction?
At excessive temperatures, enzymes usually denature or break down into other molecules, thus failing to preform their specific function.Other than that, heat does not affect enzymes much but it does increase the speed of the reaction.
Why do enzymes stop working at high temperatures in the process of photosynthesis?
Enzymes stop working at high teperatures during photosynthesis because the heat changes their shape. If the enzymes shape is altered then it can not catalize what it is supposed to.
How does heat affect cells or organisms?
heat supports life and affects the speed of function
What factors affect the activity of enzymes?
Enzymes work best in the pH and temperature that they are " designed " for. A pepsin enzyme works best in the low pH environment of the stomach, while amylase works best at mouth temperature and ~ 7 pH. Heat and out of range pH can denature enzymes and not only affect their activity but inactivate them.
How can heat affect enzyme?
Heat would make most enzymes unnecessary as added heat would allow (many) reaction to achieve activation energy without the need of a helping enzyme. In a biological system most enzymes are proteins and as heat denatures proteins the effect would be to destroy their functionality.
What is effected of excess heat or temperature on an enzymes?
With a lot of heat, the enzyme will be denatured meaning it will lose its shape and therefore its function.

Why would a washing powder of high pH or low pH be difficult to handle?
actors such as temperature and pH can affect an enzyme's rate of reaction because enzymes are sensitive to pH and heat. Most enzymes can only function in a particular temperature or pH range, and as the enzyme works out of its normal temperature and pH range, it will denature (change in shape so that the active site no longer fits with the substrate and the enzyme can't function).
How does low temperatures affect enzymes?
cold temperatures cause enzymes to inactivate, meaning they are no longer useful. at height temperatures enzymes denature, meaning they are also no longer useful. The difference is that at low temperature, when an enzyme inactivates it can always be heated, and used again. Yet after an enzyme is denatured by heat it is destroyed, this is because the heat causes the enzymes to lose its shape, making it imposible for the substrate to react with the enzyme.
What happen to an enzyme when it is boiled?
That all depends on the enzyme. The majority of enzymes found in the human body would denature (distort and lose its specific active site shape) when exposed to too much heat and stop functioning. Some enzymes can withstand incredible temperature like the enzymes used by simple volcanic organisms. Most enzymes will have evolved to work the most efficiently in their native environment.
How does heat affect cells or organisms?
heat supports life and affects the speed of function
How does heat and cold can affect a chemical reaction?
Heat generally speeds up the reaction, while cold will slow it down. The enzymes in the cold are frozen.
What is the effect of excess heat or pH on an enzyme?
it can change the shape of enzymes & active site so the enzyme is unable to work

A pepsin enzyme works best in the low pH environment of the stomach, while amylase works best at mouth temperature and ~ 7 pH.

Process causing protein shape to change in response to heat?
Denaturation- The change in shape of proteins and loss of their function when exposed to heat, acids, bases, and/or heavy metals
How can heat affect enzyme?
Heat would make most enzymes unnecessary as added heat would allow (many) reaction to achieve activation energy without the need of a helping enzyme. In a biological system most enzymes are proteins and as heat denatures proteins the effect would be to destroy their functionality.
